192. Genus Cabnia Dyar 



Cahnia Dyar, Journ. New York Ent. Soc, vol. 12, p. 108, 1904.— 

 Forbes, Cornell Mem. 68, p. 639, 1923. (Type of genus: 

 Cahnia myronella Dyar.) 



Tongue very short; but exposed between the well- 

 spaced labial palpi. Antenna pubescent ; on male with a 

 broadly scaled basal segment and a short, deep incurva- 

 tion in base of shaft. Labial palpus upturned, short, 

 not reaching to vertex; second segment triangularly 

 scaled; third segment very short and broadly scaled. 

 Maxillary palpus minute, hardly distinguishable. Fore- 

 wing smooth; 9 veins; veins 2 and 3 stalked; 4 and 5 

 united, separated from the stalk of 2-3 at base; 6 from 

 below upper angle of cell, straight; 8 and 9 united; 10 

 from the ceU, well separated from 8 at base; male with 

 a strong costal fold. Hind wing with vein 2 from well 

 before lower outer angle of cell; 5 from the angle; 7 and 

 8 completely anastomosed beyond cell; discocellular 

 vein very weak, curved. Eighth abdominal segment 

 of male simple. 



Male genitalia with apical process of gnathos a very 

 short, blunt hook. Transtilla complete. Uncus long 

 (but not longer than tegumen), moderately broad, 

 beyond its broad base but slightly tapering to rounded 

 apical margin. Harpe elongate; costs produced at 

 apex into a short, free hook. Aedeagus simple, not 

 tapering, and not appreciably enlarged at apex. Penis 

 Tmarmed. 



Female genitalia with ductus bursae membranous, 

 short (much shorter than bursa); bursa copulatrix 

 elongate, membranous, weakly scobinate over most of 

 its inner surface ; signa present but very weak, consist- 

 ing of a pair of minute disks; genital opening simple; 

 ductus seminalis from anterior end of bursa. 



On its abbreviated tongue Cabnia could go in the 

 Anerastiinae where it is placed in our recent list of 

 North American Lepidoptera. However, on male 

 genitaHa and habitus it seems to fit better into the 

 Phycitiaae. The oceUi are present and the tongue not

entirely concealed by the palps, 

 one North American species.

 McDunnough, Check list, No. 6427, 1939. 



Forewing dark cinereus, uniformly colored, many of 

 the scales tipped with dull white, giving the wing a 

 slightly frosted appearance; transverse lines obsolete, 

 or nearly so. Hind wing whitish, subpellucid; a very 

 faint dark line along termen. Alar expanse 10-11 mm. 



Genitalic characters as given for the genus. The 

 male genitalia are remarkably like those of Anagasta 

 kuhniella, differing chiefly in the proportionally shorter 

 uncus and the presence of a complete transtilla. 



Type locality: Washington, D. C. (type in USNM). 



Food plant: Unlcnown. 



Distribution: Massachusetts, Vinyard Haven (Aug.) ; 

 District of Columbia (June) ; Florida, Lake Placid (Mar., 

 Apr.). 



193. Genus Microphycita Dyar 



Microphycita Dyar, Proc. U. S. Nat. Mas., vol. 47, p. 346, 1914. 

 (Type of genus: Microphycita titillella Dyar.) 



Tongue well developed. Antenna pubescent, simple. 

 Labial palpus upturned, slender; reaching to vertex; 

 third segment as long as second, acuminate. Maxillary 

 palpus minute, filiform. Forewing smooth; 9 veins; 

 veins 2 and 3 united; 4 and 5 stalked, the stalk separated 

 from 2 and 3 at base; 6 from below upper angle of cell, 

 straight; 9 absent; 10 stalked with 8; male with costal 

 fold. Hind wing with veins 2 and 5 rather short; 6 

 greatly reduced and obsolescent at base; 7 absent; cell 

 open (discocellular vein absent). Eighth abdominal 

 segment of male simple. 



Male genitalia without apical projection from gnathos, 

 the slender lateral arms fusing into sclerotized subanal
