east; records are available from Illinois, 

 Michigan, New York, Pennsylvania, V^ir- 

 ginia, West Virginia and Wisconsin. 



Pycno psyche guttifer (Walker) 



Halesus guttifer Walker (1852, p. 16); cf , 9. 

 Pycnopsyche similis Banks (1907^, p. 122); 

 cT. 



Larva and Case. — Similar to those of 

 subfasciata. 



Adults. — In size and color similar to 

 subfasciata; the dark marks of the front 

 wing quite variable in size, shape and degree 

 of darkness. Eighth tergite of male with 

 postero-Iateral corners produced into long 

 lobes w^hich bear a dense cushion of black 

 spines along the apex. Male genitalia, fig. 

 676, with tenth tergite produced into nar- 

 row sclerotized hooks, claspers with apex 

 long, flattened and oblique at tip, aedeagus 

 very similar to that of subfasciata. Female 

 genitalia with tenth segment narrowed to- 

 ward apex, the dorsum forming a pair of 

 narrow flanges, the ventral margin incised. 



Dr. Betten has collected this species from 

 Lake Forest, Illinois, but we have not taken 

 it in our recent survey. The streams around 

 Lake Forest have changed greatly since Dr. 

 Betten collected there in about 1905-06, and 

 it is entirely possible that the colony of gutti- 

 fer which he located has become extinct in 

 that area. 



The species is widely distributed through 

 the Northeast; records are available for 

 Georgia, Illinois, Michigan, New Hamp- 

 shire, New York, Nova Scotia, Ontario, 

 Saskatchewan, South Dakota and Tennes- 

 see. 



states; records are available from Georgia, 

 Michigan, North Carolina and West Vir- 

 ginia. 



Pycnopsyche indiana (Ross) 



Stenophylax indiana Ross (1938^, p. 121); 

 0^,9. 



This species has not yet been taken in 

 Illinois, although it occurs nearby in south- 

 ern Indiana. It is possible that some of the 

 unidentified Pycnopsyche larvae which we 

 have obtained from southern Illinois streams 

 may belong to this species, but we have not 

 yet been able to differentiate the larvae of 

 indiana from other related species in the 

 genus. 



Records for the species, which are very 

 limited, include only Rogers, Indiana, and 

 Athens, Ohio; this may indicate that the 

 range of the species is south and west of the 

 main range of subfasciata, to which it is 

 most closely allied. 



Pycnopsyche luculenta (Betten) 



Stenophylax luciilentus Betten (1934, p. 345); 

 cf, 9. 



Although we have not yet taken this spe- 

 cies in Illinois, we have reared it in south- 

 ern Indiana close to Illinois, so that it may 

 be found in this state with future collect- 

 ing. The larvae are apparently indistin- 

 guishable from others in the genus. It is 

 widespread in distribution, although appar- 

 ently local, and seldom collected. Records 

 are available for Indiana, New York and 

 North Carolina. 



Pycnopsyche antica (Walker) 

 Neuronia antica Walker (1852, p. 9); 9. 



This species has not yet been taken in 

 Illinois, but J. S. Ayars has taken it in the 

 extreme southwestern corner of Michigan 

 at Almena, not far from Illinois. 



As pointed out by Betten & Mosely ( 1940, 

 p. 144), there is some question regarding 

 the identity of Rambur's species scabripen- 

 nis, under which name the present species 

 has usually been listed in North American 

 literature. Collections from North Carolina 

 indicate that the male here illustrated is the 

 one associated with the type of antica. Its 

 range extends through some of the eastern 



Caborius Navas 



Allophylax Banks (1907^, p. 119); preoccu- 

 pied. Genotype, by original designation: 

 Halesus punctatissimus Walker. 



Caborius Navas (1918, p. 362). New name 

 tor Allophylax Banks. 



Carborius used by Betten (1934), Milne 

 (1935) and Ross (1938a); misspelling. 



Both previously described species of this 

 genus have been taken in Illinois, and a 

 third form, until now undescribed, has also 

 been captured. All of them are short and 

 stocky and have broad wings. 



No North American species have yet been 

 reared. We have located many colonies of 

 larvae in Illinois, but all eliforts to rear
