Hcbard — Dcniiaptera and Orthoptcra of Haz^'aii 317 



Pronotum shining, thickly though minutely punctulate, these punctula- 

 tions the sockets of minute but stout hairs, except on convex prozonal por- 

 tion where the hairs are weaker and absent on the sulci, supplied near 

 cephalic margin with a few bristles ; length very slightly less than width ; 

 lateral margins parallel, rounding broadly into the broadly convex caudal 

 margin ; surface of pronotal portion moderately convex, with a medio- 

 longitudinal linear sulcus and two weaker, shorter sulci on each side, which 

 converge slightly caudad, remaining portions deplanate. 



Tegmina about twice as long as pronotum, with apices nearly trans- 

 verse, showing very faint obliquity; shining, though minutely but thickly 

 punctulate, these punctulations the sockets of minute but stout hairs and 

 with a few bristles latero-cephalad and many along the caudal margin. 

 Exposed portion of wings half as long as tegmina and similarly hairy. 

 Abdomen with dorsal surface shining, supplied with even finer hairs than 

 head ; glands absent ; distal tergite broadly and weakly impressed meso- 

 caudad, caudal margin transverse, ventral surface more heavily hirsute, 

 penultimate sternite with caudal margin transverse. 



Pygidium small, moderately convex declivent to lateral margins and 

 base of apical portion, very slightly longer than broad, lateral margins very 

 weakly concave, convergent to the apex, which is narrow Init angulate 

 emarginate, the latero-caudal projections thus formed being minute, acute- 

 angulate. Forceps moderately elongate, as hairy as abdomen, proximal por- 

 tion nearly straight, strongly triquetrous, distal third flattened oval in cross- 

 section, curving very gently inward to the sharp apex ; ventro-internal mar- 

 gin with a minute flange beneath the pygidium, the margin of that flange 

 suddenly and roundly terminated and alone visible from above, remaining 

 portions of ventro-internal margin showing traces of very weak serrulation.'" 



Limbs short, femora stout; first tarsal joint with length very slightly 

 greater than combined length of the minute second and elongate third 

 joints, hairy, its ventral surface with two rows of weak bristles and with 

 an internal fringe of closely placed hairs, arranged in successive lamellate 

 series. 



Description of 5 ; same data as for $ , except taken October 28, 1920. 



Agrees with male except in the following features. Abdomen broader. 

 Distal abdominal tergite smaller. Pygidium very strongly declivent, nar- 

 row, fitting tightly between arms of forceps," its ventral margin narrowly 

 lamellate and horizontal, the caudal margin of this portion transverse be- 

 tween the minute, dentiform, latero-caudal angles, from which the sides 

 of this portion are straight and parallel proximad. 



Forceps straight when closed, leaving no intervening space,'' curving 

 inward slightly at apices ; dorsal surface not flat as in male, internal 



'" From this it would appear that some males of the species liave this 

 margin supplied with weak and widely spaced serrulations. 



" The additional portions can only be seen when the forceps are 

 opened to some degree. 



'° In one female the forceps show a weak curvature and in this speci- 

 men, when closed, would not fit tightly together throughout.
