I received this specimen through the kindness of Prof. T. 

 D. A. Cockerell. 



Pkithyms intnidcns (F. Sm.) Handl. 



A i» male of this species from the collection of the British 

 Museum is before me. It bears two locality labels — ^"Santa 

 Cruz" and "San Geronimo, Guatemala (Champion)." This 

 species is much like laboriosus in general appearance, the only 

 noticeable diflFerence between it and the specimens of that spe- 

 cies withottt any yellow on the dorsimi of the abdomen being 

 the shaded lower portions of its pleura and the greater amotmt 

 of yellow in the pile of the frons above the bases of its an- 

 tennae. It can be readily separated from laboriosus structur- 

 .illy. however, by its much finer pile and by the much finer and 

 -l-.r cr punctuation of the dorsum of its abdomen, the abdo- 

 men being scantily clothed and shining much like that of varia- 

 biHt. 



Pshhynn bicolor Franklin. 



A specimen before me. from Xucumanatlan. Guerrero, 

 Mexico (7,cxx> ft. ah.), seems much like the type of this spe- 



c'v- pt that the disc of the dorsum of its thorax is not 



r. . darkened, its second dorsal abdominal segment has 



no yellow pile whatever on its hind comers, the yellow on the 

 li" ers of its third segment does not extend toward the 



II ric along the hind margin and its fourth segment has 



no yclk>w pile whatever in the middle. The punctuation of 

 the dorsum of its abdomen is about like that of intrudens, be- 

 ing much finer and sparser than that of insularis. This speci- 

 men may represent a new species, but I prefer not to give it a 

 new name until I know more about the variations of the Mexi- 

 can and Central American Psithyri. 



I have the following new habitat records for New World 

 species of Bomhns and Psithyrus : 



1. ITnrthMi ttrricoU Kirby. FarRO. No. Dakota, torty-two speci- 

 mens, represent ins all three castes: Detroit. Minnesota, three 

 workers: Lake Park. Minnesota, four males and one worker 

 (all by O. A. Stevens).
