Genus VII. TERINOS Boisd. 



Boisd. Sp. Gen. i. t. 9. f. 4. (1836). 



Head broad, hairy. 



Eyes oval, prominent, hairy. 



Maxilla? scarcely so long as the thorax. 



Labial Palpi porrect, ascending, rising above the forehead, scaly ; the scales on the first joint long ; 

 the second joint hairy at the sides. First joint short, transverse ; second four times the length 

 of the first, subcylindric, slightly swollen in the middle, tapering towards the base, and more so 

 towards the apex ; third joint about one fifth the length of the second, slender, fusiform, the 

 apex pointed. 



Antenna} rather short, slender, abruptly clavate ; the club obtuse. 

 Thorax moderately stout, oval, hairy. 



Anterior Wings subtriangular ; the anterior margin rounded ; the apex somewhat truncate ; outer 

 margin sinuate, emarginate, scarcely two thirds the length of the anterior ; inner margin nearly 

 straight, about equal to the outer. Costal nervure not reaching to the middle of the costa. 

 First and second subcostal nervules very close together, the latter thrown oft' exactly at the end 

 of the cell ; fourth more remote from the apex than from the end of the cell ; third about 

 equally distant from the second and fourth, terminating close to the apex. Upper disco-cellular 

 nervule almost wanting ; middle disco-cellular curved ; lower longer than the middle 

 disco-cellular, directed obliquely inwards to the median nervule, which it joins before the origin 

 of the second nervule. Third median nervule not much curved. Internal nervure wanting. 



Posterior Wings almost quadrangular ; the anterior margin very slightly curved ; the outer margin 

 sinuate, produced into an angle at the termination of the third median nervule ; inner margin 

 longer than the outer, emarginate towards the anal angle. Precostal nervure simple. Subcostal 

 nervure dividing very near to the base of the wing. Discoidal nervure appearing to be a third 

 subcostal, bent soon after its origin. Cell open, but with a slight indication of a lower 

 disco-cellular in a state of atrophy. Abdominal fold ample. 



Anterior Legs of the male scaly, and fringed with long hairs. Tibia shorter than the femur. 

 Tarsus shorter than the tibia, one-jointed, subcylindric, pointed. Anterior Legs of the female 

 scaly, stouter than those of the male. First joint three times as long as the rest combined, 

 cylindric, slightly curved, with a few spines below, and two stout spines at the apex, covered 

 with a tuft of hair at the base of the next joint, as is the case also with the three following
