34. Cyphocerastis picturata n. sp. 



A medium-sized, dark, and rather highly colored insect, with the 

 lower sulcus and inner face of the hind femora and lower side of the 

 abdomen deep blood-red. The head, pronotum, pleura of metathorax, 

 and upper edge and outer face of hind femora prominently marked 

 with bright yellow. Wings cerulean with fuscous apex. 



Head and thorax strongly and coarsely punctulate, the former about 

 ^s wide as the front edge of the pronotum, the eyes rather prominent, 

 fully twice as long as wide, separated above by a space a little less 

 than the diameter of the basal antennal joint, the vertex rather deeply 

 sulcate, and provided with a median and longitudinal carina of nearly 

 eciual prominence with the lateral ones, the fastigium a little depressed 

 and broadly sulcate; frontal costa between the antennae prominent 

 and fully twice the width of the vertex or the diameter of the basal 

 antennal joints, narrowing a little below the ocellus and fading towards 

 the clypeus; lateral carinas of the face parallel, moderately prominent 

 throughout; antennae black, filiform, a little longer than the head and 

 pronotum combined, the subapical joints somewhat flattened and 

 closely pitted. Pronotum provided with a prominent median carina; 

 the three transverse sulci of nearly ecjual prominence, the anterior 

 margin at middle gently rounded, the apex obtusely angled. Tegmina 

 of moderate width, reaching the apex of the hind femora and tip of 

 the abdomen. Hind femora rather robust basally, slender apically; 

 the superior carina somewhat serrate; hind tibiae slender, prominently 

 hirsute, with ten spines on their outer margin and eleven internally. 

 Prosternal spine short, acuminate; the mesosternal lobes widely 

 separated, those of the metasternum narrowly so. Valves of the 

 ovipositor elongate, slender, exserted, the apices rather strongly 

 hooked. 



General color above dull black, becoming fusco-olivaceous on the 

 disc of the pronotum and dorsal portion of the closed tegmina and the 

 abdomen above. Anterior and middle legs olivaceous; meso- and 

 metasternum olivaceous, lower surface of the abdomen vinaceous red. 

 Hind femora shining black, varied with bright yellow above and 

 externally, below and on their inner face blood-red. Vertex, fastigium, 

 a dot back of each eye and considerable portion of the face and cheeks 

 below the eyes, bright lemon-yellow. Pronotum above at its sides 

 in advance of the first transverse sulcus and behind the second sulcus 

 to the hind margin prominently striped with yellow; the lateral lobes
