Cleistepyris consobrinus sp. nov. 
Male.—Black. Mandible, distal end of scape, and second an- 
tennal segment red-brown; palpi pale; flagellum black-brown; 
tarsi and fore tibize testaceous. 
This species is closely related to C. philippinensis; in both 
Species the clypeus is only slightly keeled, broadly rounded in 
front; the mandible very much widened distally, coarsely wrin- 
kled, and 4- or 5-toothed; the antenna closely white-haired; the 
parapsidal furrows almost parallel, somewhat widened behind 
and not reaching posterior margin; and the postmarginal much 
shorter than the pterostigma. C. consobrinus however is differ- 
entiated by the following markings: The head is not punctured 
thimblelike as in C. philippinensis, but has a few close’ punctures 
which do not touch each other. Antenna longer, thinner distally, 
third joint more than twice as long as thick, twelfth at least four 
times as long as thick, whereas in C. philippinensis it is not 
three times as long as thick. Pronotum, mesonotum, and scutel- 
lum smooth, with several scattered punctures. Veins of distal 
Submedian cell very pale. Abdomen without red marking, 
whereas in C. philippinensis the posterior margin of second ter- 
gite is more or less red-brown. 
Length, 6 millimeters.

Cleistepyris minimus Kieff. 
Male.—In this species mandible and clypeus are shaped as in 
C. consobrinus and C. philippinensis. The palpi are pale, the 
antenne pale yellow to brownish, becoming gradually darker 
distally. The postmarginal is almost twice as long as the pte-
