REVISION OF LEUCOSPIDAE 59 



subangulate; fifth tergite in median line moderately depressed, here o-8 as long as first tergite, 

 1-85 times as broad as medially long. 



cj. As redescribed by Schletterer (1890), in structure similar to L. pictipyga described above. 

 Gaster with apical yellow bands on tergites 4 and 5, the sixth broadly yellow but with a black 

 streak at each spiracle and a small spot medially above, sometimes connected with basal black 

 band. In the <$ from Mazatlan the gaster looks broader because its apex is more broadly 

 rounded. 



L. khigii is in many respects intermediate between L. pictipyga sp.n. and the 

 two following species, which differ in still shorter body, broader gaster and longer 

 genae. 



Biology. Still unknown. 



Distribution. Mexico, Costa Rica. 



Material examined. 



Type data given in synonymy.

Leucospis anthidioides Westwood 



(Text-figs 53, 56) 



Leucospis Anthidioides Westwood, 1874 : 135, pi. 25, fig. 7, $. LECTOTYPE $ (here designated), 

 Brazil: Amazonas (UM, Oxford) [examined]. 



The apparently single original specimen is designated as lectotype. 



L. anthidioides was separated from Leucospis Fabricius by Shipp (18946 : 245) 

 as genus Exochlaenus Shipp. The present revision shows that Shipp's genus has 

 no justification, for there is no real and distinct gap between the species-group in 

 which anthidioides belongs and the other species of the genus. 



The male is similar to that of L. xylocopae Burks; both have last sternite 

 emarginate in middle, sixth sternite subquadrate, but the fifth is distinctly 

 transverse, the fourth still more transverse and its hind margin slightly emarginate; 

 in xylocopae the fifth sternite is subequal to the sixth and also the fourth is hardly 

 transverse. 



Biology. Reared from Xylocopa submordax Cockerell, Apidae, in Trinidad. 

 Distribution. Trinidad, Surinam, N. Brazil.
