lar colored hairs, which extend narrowly along the sutural margin to 

 the broad vitta at middle. 



Abdomen beneath finely, sparsely punctate, the punctures con- 

 nected transversely at middle of basal segment by sinuate lines, some- 

 what imbricate at sides of basal segment, very sparsely clothed with 

 short white hairs, and with a spot of more densely placed white 

 hairs at sides of the third segment; sides broadly, abruptly exposed 

 above; first segment convex and without long hairs at middle; last 

 segment rather narrowly rounded at apex; suture between first and 

 second segments not visible ; vertical portions of first segment with a 

 spot of densely placed white hairs; pygidium longitudinally cari- 

 nate anteriorly, but the carina not projecting at apex. Prosternum 

 sparsely, finely punctate, more or less scabrous, and sparsely clothed 

 with short recumbent white hairs ; prosternal lobe broad, moderately 

 declivous, and broadly subtruncat* in front; prosternal process 

 broad, the sides parallel to behind the coxal cavities, then arcuately 

 narrowed to the apex, which is rather acute. Tibiae slender, an- 

 terior pair arcuate, and the anterior and middle pairs armed with a 

 short tooth on inner margin at apex. Posterior tarsi about one-half 

 as long as the tibiae, and the first joint subequal in length to the 

 following joints united. Tarsal claws cleft near middle, the inner 

 tooth broad and shorter than outer one, and not turned inward 

 (claws on anterior feet missing). 



Length, 6 mm. ; width, 1.25 mm. 



Type locality. — Hamburg farm, Costa Rica. 



Type.— C2it. No. 41607, U.S.N.M. 



Described from a unique female collected on withered leaves at the 

 type locality, April 11, 1926, by Ferd. Nevermann. 



I take great pleasure in naming this species after my friend, Ferd. 

 Nevermann, of San Jose, Costa Rica, through whose careful and 

 energetic collecting our knowledge of the interesting fauna of Costa 

 Rica has been very greatly increased.
