First record of necrophagy by Scybalocanthon nigriceps Harold (Coleoptera, Scarabaeidae, Scarabaeinae)

First record of necrophagy by Scybalocanthon nigriceps Harold (Coleoptera, Scarabaeidae, Scarabaeinae). The S. nigriceps specimen was observed making small cuts and removing portions of the carcass of a frog Haddadus binotatus (Spix) in February 24, 2011, in Serra do Japi, São Paulo State, Brazil. This note presents another record of necrophagy for Scybalocanthon.

Description of immature stages of Hoplia mexicana Harold and H. squamifera Burmeister (Coleoptera, Melolonthidae, Hopliinae)

ABSTRACT Third stage larvae and pupae are described based on specimens collected in Mexico: Oaxaca (Cerro Zempoaltepetl), and Chiapas (Amatenango), respectively. Pupal characters are described for the first time for American Hopliinae. Habitus images and figures of diagnostic characters as well as comments on the differences between these larvae and those of Hoplia callipyge LeConte, 1856 and H. equina LeConte, 1880, the only Hopliinae larvae previously known in New World, are also included.

Sôbre os inimigos naturais da lagarta das palmáceas Brassolis sophorae sophorae (L.) (Lep., Brassolidae)

Brassolis sophorae (L.) (Lep., Brassolidae) is an old and important pest of some Brazilian Palmae, among which Cocos nucifera L. and Copemicia cerifera Mart, are the most valuable economically. Eggs are attacked by Anastatus reduvii (Howard) (Eupel-midae) and Telenomus sp. and Telenomus nigrocoxdlis Ashmead (Scelionidae), the larvae being destroyed by Withemia pinguis (F.) (Tachinidae). Six other insects devellop inside the pupae : Xanthozona melanopyga (Wiedmann) and Belvosia sp. (Tachinidae) and the Hymenoptera Brachymeria annulata (F.), B. incerta (Cres-son), Spilochalcis nigrifrons Cameron and S. morleyi Ashmead (Chalcicidae), the last of them being principally treated in this paper. A species of Sarcophagidae (Sarcophaga lambens Wiedmann) was also noted, some flies being gotten from a single pupa. In Piracicaba (State of S. Paulo, Brasil), according to the Author's observations, B. sophorae principal enemy is X. melanopyga, to which our attention has to be directed in a biological fight against the mentioned Brassolidae. The reported Telenomus sp. is also very harmful to B. sophorae eggs. In the whole zone of its distribution, the hosts of B. sophorae caterpillars are Palmae plants, appearing sporadically feeding on banana and sugar cane leaves.

Notas sôbre Pholus vitis (L., 1758) (Lep., Sphingidae)

The Brazilian entomological literature mentions some species of Sphingidae living on Vitis vinijera leaves, one of which is Pholus vitis (Linnaeus, 1758), of the subfamily Macroglos-sinae. The last instar caterpillar as well as the pupa are described in this note, some biological informations being also given.
