Female. 

 Bassus carpocapsae Cushman, Proc. Ent. Soc.Wash., vol. 17, 1915, p. 142. Male. 



Type. — In the United States National Museum. 



Most similar to laticinctus, but distinguished especially by the dif- 

 ferences noted in the key. Face short and very broad ; labial palpi 

 short, the third segment minute; malar space not distinctl}^ half the 

 eye height; temples very narrow, strongly receding; ocell-ocular hne 

 about twice the diameter of an ocellus : frontal impressions very small 

 and shallow; antennae usually 32 to 38 segmented, very slender; 

 scape rather slender; first flagellar segment not distinctly as long as 

 the scape and pedicel combined; head scarcely hollowed out behind; 

 parapsidal furrows strong, f oveolate ; propodeum rather short, convex, 

 strongly declivous behind, entirely coarsely rugose; mesopleural fur- 

 row usually distinctly foveolate; areolate of fore wing triangular, 

 petiolate; medius obsolescent basally; first abscissa of mcdiella fully 

 as long as the second; abdomen stout; first tergite short and broad 

 at apex, longitudinally striate; second and following tergitcs polished; 

 ovipositor sheaths about two-thirds as long as the bod}". Head 

 black, with narrow ferruginous superior orbital lines, and sometimes 

 with face and cheeks mostly ferruginous; thorax black; legs testace- 

 ous, the posterior coxae often more or less black; posterior tibiae 

 dusky at extreme tips, less broadly so than in laticinctu'^ ; posterior 

 tarsi more or less dusky; wings slightly dusky; abdomen varying 

 from black, with second and most of third tergites testaceous, to 

 entirely testaceous with only slight duskiness on the fu-st tergite. 



In addition to the type series, which contains specimens from 

 Massachusetts, Delaware, Virginia, Maryland, and Pennsylvania, 

 most of which weie reared from Carpocapsa pomonella Linnaeus, the 

 National Museum has five specimens recorded as a parasite of the 

 same host of Dover, Delaware, under Quaintance No. 9287 (E. R. 

 Selkrigg) . 



34. BASSUS LATICINCTUS (Cresson) 



Microdus laticinctus Cresson, Canad. Ent., vol. 5, 1873, p. 53. 

 Microdus ocellanae Richardson, Canad. Ent., vol. 45, 1913, p. 211. 

 Microdus earinoides Du Porte (not Cresson), Rep. Quebec Soc. Protection 

 Plants, vol.7, 1915, p. 76. 



Type. — The type of laticinctus is in the Philadelphia Academy of 

 Science; that of ocellanae is in the Canadian National collection at 

 Ottawa. 



Closely related to carpocapsae, but undoubtedly distinct and sepa- 

 rable by the differences noted in the key and in the above character- 

 ization of carpocapsae. It also somewhat resembles annulipes, and 

 has sometimes been identified as earinoides Cresson, which is a syn-
