Genus PEKILAMPITS Latreille 

 Key to certain Oriental species of PerUampus. 



1. Base of abdomen opaque, covered with small punctures 2. 



Abdomen entirely smooth and shining 4. 



2. Bright green; area laterad of notauli striate P. singaporensis sp. nov. 



Dark green or greenish black - 3. 



3. Area laterad of notauli smooth; scutellum distinctly triangular pos- 



teriorly and emarginate P. orientalis sp. nov. 



Area laterad of notauli sculptured; scutellum obtusely subtriangular 

 posteriorly and not emarginate P. punctiventris Crawford. 



4. Dark green; posterior orbits with strong striae except f 



Black; posterior orbits except a 



P. neslotes Crawford. 



The bright green color separates this species from the other 

 Oriental forms.

 shining, smooth except for a few setigerous punctures, the an- 

 terior margin depressed and slightly, broadly, arcuately emar- 

 ginate; malar furrow distinct; carina defining scrobal cavity 

 dorsally extending ventrally to a point opposite the insertion 

 of antennae ; scrobal cavity sharply angulate dorsally and termi- 

 nating immediately behind anterior ocellus; area below lateral 

 ocelli with a few raised lines; posterior part of vertex with a 

 few transverse rugae; posterior orbits smooth, shining except 

 posteriorly where there are a few dorsoventral striae; f unicle 

 wanting; pronotum, scutum (except as mentioned below), and 

 scutellum with large umbilicate punctures; notauli foveolate;
