ADMESTINA Nov. Gen. 



Cephalotliorax low and plane, a little widest opposite the middle of thoracic 

 part, more contracted in front than behind, less than twice as long as 

 wide, the cephahc and thoracic parts not separated. The thoracic 

 part is twice as long as the cephalic part, and is truncated behind. 

 In front the sides are nearly vertical while behind they are rounded. 

 Quadrangle of eyes much wider — nearly twice — than long, and very 

 little wider behind. Anterior row a little curved upward, the middle 

 twice the lateral and near together; the lateral separated from the 

 middle by almost one-half their own diameter. Second row small and 

 placed two-fifths from the anterior lateral. Dorsal eyes slightly larger 

 than lateral and as wide as the cephalothorax at that place; plainly 

 further from each other than from the lateral borders. Clypeus one- 

 half as high as the large middle eyes. Sternum nearly oval, not pro- 

 duced between the cox^ of the first pair, which are nearly touching. 

 Maxillae enlarged and blunt at the extremity. Labium as wide as 

 long, and less than half of the maxiUee. Falces weak, wide as mid- 

 dle eyes, and a little longer than the face, vertical, parallel. Legs 

 4, 1, 3, 2; first pair stoutest; the tibia and patella of the first much 

 shorter than the cephalothorax. Tibia and patella of the third shorter 

 than tibia and patella of the fourth, the latter longer than the tarsus 

 and metatarsus of the fourth. Legs without spines except on raeta- 

 tarsus of the first pair. Abdomen rather long and narrow. Nearest 

 Hyctia Simon, but differs in the much greater width of the quadran- 

 gle of the eyes, in the quadrangle being wider behind, not parallel; 

 and the relative length of the legs. The sternum is not narrow.
