3. Athipidki Alexander, {domest'im. <;r()up): antennae of hoth 



sexes subpectinate to simple: (lomcstJcd. shaiinoni. 



The habits and haunts of the adult Hies are iniit-h as in Dicran- 

 oinyki. The early stages occur in decaying organic matter or beneath 

 the bark of dead trees. 



Key to Species 



1. Wings with an abundant pale brown or gray dotting in all cells 2 



Wings with the markings larger, confined to vicinity of veins 3 



2. Body-coloration grayish, praescutum with a broad brownish black median 



line : mediotergite gray ; wings with a heavy brown pattern along costal 

 margin, the dark areas subequal in extent to the interspaces ; legs brown : 



antennae ( S ) bipectinate maculata 



Body-coloration yellowish brown, praescutum without a dark median line ; 

 mediotergite with a large black triangle : wings with small brownisli 

 black spots at base, at supernumerary crossvein in cell Sc. origin of Rs, 

 fork of Sc and over Rn, all these areas much smaller than interspaces ; all 

 cells with numerous paler dots ; legs chiefly yellow, femoral tips weakly 

 darkened ; antennae subpectinate in both sexes shannon! 



3. Praescutum reddish brown, yellow pollinose, with narrow darker lines ; pleura 



dull yellow, with two narrow blackish longitudinal stripes ; antennae dark, 

 with penultimate and antepenultimate segments abruptly light yellow ; 

 vi-cii usually far before fork of M ; antennae subpectinate in both sexes 



domestica 

 Praescutum brown, pruinose, with a broad, brownish black, median stripe ; 

 pleura grayish or plumbeous, the stripes narrow or lacking; antennae 

 black throughout ; ;;;-(-/( at fork of M ; antennae ( S ) unipectinate or bi- 

 pectinate • ^ 



4. Wings with the dark pattern beyond origin of Rs only, including large 



rounded clouds at origin and fork of Rs, stigma, and outer radial cells : 

 costal cell uniformly darkened; thoracic pleura unstriped ; abdomen dark 



brown, hypopygium paler ; antennae ( S ) unipectinate f idelis 



Wings with a series of about five major grayish brown areas along costal 

 margin, two being before origin of Rs : costal cell not uniformly darkened: 

 thoracic pleura with a narrow longitudinal stripe ; abdominal tergites yel- 

 low, the caudal half of individual segments dark brown; antennae (i ) 

 bipectinate bryanti

A small blackish spot on either side of cephalic end of praescutum ; 

 lateral praescutal stripes subobsolete; pleural stripe very narrow, that 

 on sternopleurite even less distinct. Flagellar branches ( $ ) relatively 

 short; of ? relatively long, unipectinate. Legs black, basal half of 

 fore, basal two-thirds of remaining femora, obscure yellow, (iround 

 color of wing grayish subhyaline, the dark areas narrowly bordered 

 by white, besides the costal areas, with narrower seams along cord and 

 outer end of cell 1st Mo, and with gray streaks in centers of certani 

 cells. Male hypopygium (Fig. 37, B) : rostral spines three, unus- 

 ually short. <3. L. 6.5-7 mm.; w. 8-8.5 nmi. 9. L. 9-10 mm.; w. 

 9-9.5 nun.
