NOTES ON LUCANID^. 



By John W. Angell, New York. 



Pseudolucanus mazama var. nov. bicostatus: Differs from the 

 typical form of mazama by the more elongate elytra, which are 

 markedly costate, the two costas being broad and rather flat. The 

 narrow form of bicostatus at once distinguishes this variety from 

 others which show faint indications of costse. Type one male in 

 my collection given to me by Mr. R. P. Dow, from Ft. Wingate, 

 N. M. (John Woodgate collector). Length 30 mm. 



Platycerus pedicillaris vs. thoracicus: In Memoirs of the Cole- 

 optera, V, p. 374, Col. Thos. L. Casey says : " After carefully 

 reading the description of (P.) pedicellaris Mollenkamp, de- 

 scribed from California (Ent. Zeit., V, 191 1, p. 304), I am unable 

 to find any notable difference between it and P. thoracicus Csy. 

 It is highly probable, therefore, that it is . a synonym of that 

 species." 



In this connection I should say that I have in my cabinet one 

 of the original cotypes of P. pedicellaris Mollenkamp, sent to me 

 by F. W. Nunenmacher, the collector, and two specimens of P. 

 thoracicus, identified by Col. Casey himself, and the difference is 

 very marked. Thoracicus is finely punctured, flat in body, and 

 easily discernable as a member of the quercus group; while P. 

 pedicellaris has elytra coarsely striate and is much stouter in 

 body, resembling in general appearance P. keeni Csy. This, I 

 think, indicates specific distinctness. 



LIVING PUP^ FOR SALE. 



The sale of Saturniid cocoons collected by members of the 

 Brooklyn Entomological Society, proceeds to go to its publication 

 fund, insures that during the coming season experiments in 

 hybridism and other biological research will be greater than ever 

 before. 



We can still supply cecropia and cynthia in unlimited quanti-
