Notes for the genus; other spines short and heavy, below concave, 

 with margins of this sulcation minutely serrulate in both sexes, the 

 disto-internal spine not specialized. Ovipositor moderately long, 

 nearly rigidly straight ; apex with the margin of that portion formed 

 by the dorsal valves straight and armed with serrulations, the portion 

 formed by the ventral valves unarmed. 



The present subgenus finds its nearest relationship in the North 

 American subgenera to Allonemohius, from which it differs in the 

 shorter heavier spines of the caudal tibiae, the ovipositor which has 

 the apex with that portion formed by the dorsal valves not obliquelj- 

 subtruncate or armed with teeth and a more robust general appear- 

 ance. 



Nemobius panteli n. sp. 



1896. Nemobius mexicanus Scudder (not of Walker, 1869), Jour. N. Y. Ent. 

 Soc, IV, p. 107. (In part.) [Mescico, Mex.] 



This species appears to be related more nearly to Nemobius fasciatus 

 socius than to any of the other North American species of the genus. 

 It differs distinctly from that species in the characters given in 

 separating the present subgenus from the subgenus Allonemohius 

 as well as in certain important characters of color pattern. 



A certain relationship is shown to Nemobius brasiliensis in the 

 characters of the apex of the ovipositor, but in other respects these 

 species differ very widely. 



Fig. 16. — Nemobius panteli. Ovipositor. (Greatly magnified.) 



Type: 9; Mescico, Mexico. (E. Palmer.) [Scudder Collection.] 

 Description of Type. — Size large, form robust; head large, very 

 full and rounded, about as wide as the pronotum. Maxillary palpi 

 much as in N. fasciatus, and eyes and pronotal proportions likewise 

 similar. Tegmina not as long as caudal femora, apex at humeral 

 angle less broadly obtuse-angulate than in most species, sutural 

 margin passes into distal margin with scarcely any angulation, 

 longitudinal veins not heavy, cross-veinlets very faint. Wings 

 absent. Ovipositor considerably shorter than the caudal femur, 

 nearly rigidly straight, stout; apex with that portion formed by the 

 dorsal valves straight and armed with serrulations. Spines of 

 caudal tibiae distinctive, as given in description of subgenus. 



The allotype bears the same data as the type and is also in the 

 Scudder Collection.
