Description of Allotype. — Size larger than male; form robust. 

 Head, maxillary palpi, eyes, and pronotum much as in the type. 

 Tegmina almost equal in length to caudal femora, apex at humeral 

 angle broadly but distinctly obtuse-angulate, sutural margin passes 

 into distal margin with a distinct sharply rounded obtuse-angulation, 

 longitudinal veins very conspicuous, cross-veinlets faint. Wings 

 absent. Supra-anal plate and cerci much as in fasciaius. Ovipositor

Figs. 19 and 20. — Nemobius bruneri. Cephalic (Fig. 19) and dorsal (Fig. 20) 

 aspect of color pattern of head. (X 4.) 



moderately heavy, a little over half as long as the caudal femora, 

 slightly but noticeably curved, apex of same very narrowly sub- 

 lanceolate^^ with that portion formed by the dorsal valves armed, 

 the upper margin serrate, these teeth regular, heavj^ with immediate 

 apices very sharp. Subgenital plate scoop-shaped, very acute- 

 angulate emarginate mesad with margins broadly rounded.

51 This specimen, as well as all but two of the others of the present species 

 before us, has the dorsal and ventral valves of the ovipositor considerably sepa- 

 rated at their extremities; the two specimens mentioned also indicate this cleavage, 

 but to a much less degree. We have noted this peculiarity to be very rare in 

 other species of Nemobius, and in all cases the irregularity of its proportions and 

 the distorted appearance of the apices of the valves prove it to be an abnormality. 

 It is quite probable that peculiarities in the oviposition of the insects has brought 

 about this result, and a study of these habits in this and other species should 

 prove most interesting.
