PRELIMINARY LIST 



three-fourths the length of the clypeus, superiorly very obtusely 

 and evenly rounded. Vertex a third longeron the middle than 

 next the eyes, width between the eyes two and one-tliird times 

 the length at the middle, finely sliagreened anteriorly. Pronotum 

 little less than twice as broad as long, and little more than twice 

 the length of the vertex, curvature one-half of the length, pos- 

 terior margin straight, disc with scattered shallow punc- 

 tures. The black scutellar suture nearly straight. Hind mar- 

 gin of the last ventral segment nearly truncate, posterior angles 

 obliquely cut off, pygofers with stout hairs on tlie distal half. 

 Color greenish yellow. Face yellow, sutures of the front and cly- 

 peus and sockets of the antennae black, above dusky with sev- 

 eral rather indistinct transverse lines. Vertex yellowish to 

 brownish with a fine black median line on the basal half, and two 

 large black spots anteriorly between the compound eyes. Prono- 

 tum greenisli yellow, anteriorly with a transverse black line 

 nearly parallel with the anterior margin, its lateral ends bent 

 forward. Elytra pale greenisli, hyaline, nervures yellowish. 

 Tergum black, segments narrowly margined with yellowish. 

 Venter and pygofers yellow, valves black. Sternum black. Legs 

 pale yellow. 



Male: Sutures of the face more heavily black, the face above 

 darker with a small black spot on either side above antennae. Vertex with a black line
