5c. Ischnus inqiiisitorius assimilis (Uchida), new status 



Hahrocryptus assimilis Uchida, 1930, Journ. Fac. Agr. Hokkaido Imp. Univ., 

 vol. 25, p. 313; ?. Type: ?, Kiminai, Sachalin (Sapporo). 



Male: Unknown. 



Female: Postpetiole and second tergite a little less mat than in 

 other Nearctic subspecies. 



Black. Eye with a whitish orbital mark dorsally; palpi fuscous; 

 scape, pedicel, and basal part of flagellum dark brown, the rest of 

 flagellum black with a white band that covers 3.5 to 4 segments; 

 tegula dark brown; second trochanters brown to ferruginous; femora 

 fulvoferruginous, the apical 0.3 ± of hind femur faintly infuscate in 

 specimen from Sachalin, moderately infuscate in specimen from 

 Alaska; tibiae fulvoferruginous, the apex of hind femur faintly in- 

 fuscate in specimen from Sachalin, distinctly infuscate in specimen 

 from Alaska; front and middle tarsi fulvoferruginous, somewhat 

 infuscate apically; hind tarsus bro^vTl, its second and third segments 

 whitish, the third segment with a subapical brown area in the specimen 

 from Alaska. 



This subspecies is distinct from the subspecies pectoralis in that it 

 has no ferruginous on the coxae or thorax (in the female, at least). 

 Some specimens of pectoralis from Yukon and Alaska approach 

 assimilis and may be considered intermediates. If there is any 

 ferruginous on the coxae and thorax, the specimens have been classified 

 as pectoralis, though some other distinction may later prove to be more 

 natural or useful. 



Specimens: 9, in rotary trap, Matanuska, Alaska, June 20, 1944, 

 J. C. Chamberlin (Townes). 9, Karafuto, Sachalin, Siberia, C. 

 Watanabe (Townes). This latter specimen was compared with 

 Uchida's tj^pe.

 poral orbit, vertical orbit, band on flagellum, tegula, dash on upper

 (rarely these are joined), usually collar, rarely lower edge of pronotum, 

 subtegular ridge, spot on scutelluni, postscutellum, spot on upper 

 division of metapleurum, often an irregular subapical transverse band
