30 ENTOMOLOGICAL SOCIETY 



— Mr. Emerton, upon invitation, gave a short talk, stating 

 that he had come to Washington to work over some material 

 in the Arachnida and to study the collection of Mr. Banks. 



— Doctor Dyar exhibited specimens of mosquitoes belonging 

 to the genus Deinocerites, and spoke of the fact that these are 

 known to breed only in mangrove swamps at the tide-water 

 level and in the holes of crabs. 



— Mr. Quaintance spoke of the recent destructive outbreak 

 of Enarmonia prunivora Walsh in apple orchards. This lepi- 

 dopterous pest had been supposed to be connected in some way 

 with the plum curculio (Conotrachelus nenuphar Hbst.) and 

 had been bred from black knot. The first brood lives in the 

 calyx of the apple and there pupates. The second brood often 

 lives entirely outside. The species has been taken from Onta- 

 rio south, and as far west as British Columbia. 



— Mr. Burke exhibited four species of the coleopterous 

 genus Trachykele. One of these was found in cedar of Leba- 

 non at New Orleans. Another came from Mexico and a third 

 from California ; he gave notes upon the species and remarked 

 that they all apparently feed upon cedar of some kind, one 

 species ruining cedar which is used for fence posts. 



— The following papers were offered for publication : 



NEW TROPICAL AMERICAN NEUROPTERA. 



By Nathan Banks. 



About a year ago Prof. F. Campos, of Guayaquil, Ecuador, 

 sent me a small collection of neuropteroid insects from that 

 country. Several species in the collection are new, and the 

 descriptions of these forms constitute this paper. I have added 

 the description of a new ant-lion fly from Lower California. 

 Three of the new species from Ecuador belong to the peculiar 

 genus Dimares, only two species of which were previously 

 known. 



Dimares bellulus, n. sp. 



Face yellowish, with a transverse brown band from eye to eye, con- 

 nected in middle to the brown above, thus forming two pale spots 

 below the antennae ; a large blackish spot between and above antenn^ne ; 

 vertex pale yellowish, with brown streaks, a median pair close together
