BOMBYLIIN.E. 259 



iato a blaat coue with two short strong brown blunt spines at 

 •extreme tip and a similar smaller spine above them, placed a little 

 anteriorly. Venter with a transverse row of moderately long 

 pale hairs placed behind the middle of each segment. 



Leiir/th, 10-12 mm., measured along dorsal line from tip to tip; 

 probably variable. 



Subfamily BOMBYLIIN^E. 



Head smaller than in ANTHRACiisriE, rarely transverse or wider 

 than thorax ; back of head much puffed out ; eyes contiguous or 

 subcontiguous in o , distinctly separated in 2 ; if wide apart in 

 c? , then abdomen short and broad. Antennae approximate at 

 base, variable in structure, with au apical style of variable form, 

 sometimes imperceptible. Proboscis variable in length, generally 

 elongate and porrect. Thovax generally well, often considerably, 

 arched, usually with dense furry pubescence; in some genera 

 nearly bare. Abdomen usually short, broad and rounded, rarely 

 conical; frequently with dense furry pubescence. Ijegs generally 

 long and thin, sometimes bare or apparently so, often with stick- 

 like spines below the femora, or with spicules, or with a circlet of 

 apical spines to the tibiae. Two pulvilli. Wings with the prae- 

 furca short ; one to three submarginal cells ; three or four 

 posterior cells ; 2nd and 3rd longitudinal veins usually emerging 

 at an acute angle, the latter approximately opposite base of discal 

 cell ; 3rd vein nearly always forked ; discal cell rarely absent ; 

 anal cell open or closed. 



This subfamily differs from the AiSTiiRACiNyE by the divergence 

 of the 2nd and 3rd veins at au acute angle at some distance 

 before the anterior cross-vein, from the Toxophouiis^^ and 

 SvsTROPiN^ by the short rounded abdomen, and from the 

 LoMATiiN.i; (less distinctly) by the rounder abdomen, the longer 

 proboscis, and less upturned 2ud vein.
