Mr. Caudell mentioned that he had observed a Calosoma 

 larva engaged in eating the purslane larva before referred to. 

 The beetle larva seemed to be blind. Dr. Howard, speaking of 

 the sight of insects, said that it was by no means proved that in 

 sects with eyes see as do human beings. He referred to the work 

 of Von Beethe on the Psychology of Ants, Bees, and Wasps as 

 bearing out this statement. 



The paper for the evening was by Dr. Dyar, and was enti

A REVIEW OF THE SPECIES OF HAPLOA. 



By HARRISON G. DYAR. 



The genus Haploa comprises a series of closely allied forms of 

 broad- winged Arctiidae, formerly referred to the European genus 

 Callimorpha. It has been the subject of considerable discussion 

 among American entomologists. Professor J. B. Smith gave a 

 good account of the genus, and brought the history of its litera 

 ture down to 1887 in an article published in the Proceedings of 

 the U. S. National Museum of that year. He recognized nine 

 species. Since then the following has appeared : In 1887 Mr. 

 H. H. Lyman published in the Canadian Entomologist, making 

 eight species. His conclusions were much the same as those of 

 Prof. Smith, and the differences of these authors were finally 

 reconciled, the result being shown in Smith's List of the Lepidop- 

 tera of Boreal America, 1891, with nine species clymene, colona, 

 lactata, lecontei, contigua, suffusa, confusa, fulvicosta and ves- 

 talis. In 1893 Neumoegen and Dyar published in the Journal of the 

 New York Entomological Society, recognizing but seven species, 

 lactata being attached to clymcne and fulvicosta to lecontei as 

 varieties. Two older names, suppressed by Smith and Lyman, 

 were revived, and a new name proposed for one of the immacu 

 late forms. Vestalis was not identified. In 1896 I published in 

 Entomological News a short article intended to show what was 

 known of the larvae of these forms ; little enough it is. I recog 

 nized six species, following the revision published with Mr. 

 Neumoegen, but correcting the confusion that we had fallen into 

 in regard to the white forms. I recognized vestalis as the white 

 form of lecontei, and fulvicosta as that of reversa (suffusa], 

 which Neumoegen and Dyar had unnecessarily renamed. In 

 1897 I published in Canadian Entomologist on a good series of 

 the formfulvicostQ) describing the larva and showing that the 

 genitalic characters used by Prof. Smith were too variable to be 

 reliable. In 1899 Prof. Smith published in Entomological News 

 a description of Haploa triangular is, and in 1901 Mr. H. D. 

 Merrick named a new variety of H. lecontei in the same journal.
