NEOBROTICA AND RELATED GENERA — BLAKE 333 



mens from Cochabamba and Beni River, Salinas, Bolivia, collected 

 by M. Stuart, July 1895. 



Remarks: There is considerable variation in the markings of this 

 species. One specimen has entirely pale legs, in others the variation in 

 the pale terminal jomts of the antennae is noticeable, and the elytral 

 markings vary to the extent that the basal spot may be so large as to 

 leave only a narrow sutural and lateral dark vitta ; the fascia below the 

 middle varies from a narrow to a wide band. Bowditch has attached 

 the manuscript name hella to this species. 



Hystiopsis zonata, new species 



Figure 76 



About 6 mm. in length, oblong oval, feebly shining, the elytra 

 strongly costate with the intervals striately punctate, the head down 

 to antennal sockets piceous, pale yellow in lower front, antennae 

 brown with the apical joints paler; prothorax pale, elytra piceous 

 with a pale margin and a pale transverse fascia below the middle; 

 body beneath pale with the breast dark, femora pale with a dark 

 streak; tibiae and tarsi piceous. 



Head with the interocular space about half width of head, occiput 

 finely punctate, a median depression above frontal tubercles, no carina 

 down lower front but the lower front depressed with a small trans- 

 verse ridge on either side under the antennal sockets. Occiput to 

 antennal sockets piceous, lower front pale yellow, mouthparts brown. 

 Antennae brown with the apical joint pale and its tip dark. Prothorax 

 not twice as broad as long with slightly curved sides and a transverse 

 depression, entirely pale. Scutellum piceous. Elytra strongly costate, 

 the intervals with striate, sometimes geminate punctation, alutaceous, 

 feebly shining; dark piceous with a feeble violaceous blue lustre, 

 the margin pale yellow and a transverse pale fascia below the middle. 

 Body beneath pale with a piceous breast, femora pale with a dark 

 streak above and the hind femora with a dark apex; tibiae and 

 tarsi more or less dark, in the male the front tibiae thickened and the 

 first tarsal joint long and wide. Length 6.2 mm.; %vidth 3 mm. 



Type, male, CAS, from Valley of the Monzon, Tingo Maria, Peru, 

 collected by E. I. Schlinger and E. S. Ross, Sept. 18, 1954. 



Remarks: The similarity of all these species with the depressed 

 lower front of the face makes the group as homogeneous as the species 

 of Eucerotoma, a group of larger beetles with stronger costae and 

 more developed male characters. Tliis species is a little larger than 

 H. hella, and the male has more strongly dilated first front tarsal 

 joints.
