orientalis sp. no v. 



This species seems to be allied to Perilampus megalaspis Cam- 

 eron but differs in the lack of striae on the malar space, the 

 absence of white hair on the head, etc. 



Female. — Length, 3.75 millimeters. Clypeus gently convex, 

 shining, with a few setigerous punctures, the anterior margin 

 gently rounded out, not depressed; malar furrow distinct; 

 scrobal cavity limited dorsally by a short carina (extending a 

 short distance below ocelli) , the rest of the area dorsad of the 

 depression with short striae which extend ventrally nearly to a 

 point opposite the insertion of antennae; these striae do not 

 reach the inner eye margins; lateral areas of frons and vertex 

 shining, without definite sculpture ; posterior orbits shining and 

 without sculpture except for a few striae posteriorly; flagellum 

 stout, first funicle joint a little longer than second; pronotum 

 with three rows of umbilicate punctures ; scutum (except as men- 

 tioned below) and scutellum with umbilicate punctures ; notauli 

 not sharply defined; the area just lateral to notauli shining and 

 without sculpture; scutellum narrow posteriorly and distinctly 

 emarginate ; posterior face of propodeum shining, with a median 

 ridge bounded laterally by a foveolate depressed area; base of 

 abdomen subopaque with close, fine punctures. Head and thorax 

 dark metallic green, abdomen blue-black; anterior tarsi pale, 

 other tarsi wanting; wings hyaline, venation pale brown.

 Perilampus nesiotes Crawford. 



A single female from Ilocos Norte, Luzon, collected June 2, 

 1912, by C. S. Banks and bearing the word "Bangui" on the 

 label agrees very closely with the unique type of the Sumatran 

 species P. nesiotes Crawford. The Luzon specimen is a trifle 

 larger, but I see no characters by which it can be separated from 

 the type.
