Mexico: Vera Cruz, Atoyac, V., 2 $£, one the TYPE, (H. H. Smith). 



Body predominantly black but the head red ; tergite 1 almost yellow and a pale spot at 



the side of tergite 3 ; tergite 2 much less exaggerated in size and sculpture than in 



seres and, together with 3, not occupying the greater part of the gaster beyond 



tergite 1 ; apical tergites not short and not retracted noticeably beneath tergite 3 



? pelides sp. n. 



Brazil: Nova Teutonia, v. 1937, r 6\ {Plaumann) (see couplet 3). 

 Body and legs entirely honey-yellow ; stigma narrower, emitting the radius more 

 obviously distal to middle ; abscissa 1 of the radius slightly longer and slightly 

 curved ; tergite 2 less transverse, two and a half times as wide as long, its coarse but 

 very superficial sculpture present only towards sides . . fortipes Cameron 64 



British Guiana. Only type female seen ; in British Museum (Nat. Hist.). 

 Thorax at least in part, and the hind coxa entirely, black ; stigma wider, emitting 

 the radius less obviously distal to middle ; abscissa 1 of the radius slightly shorter 

 and virtually straight ; tergite 2 more transverse, fully three times as wide as long, 

 its sculpture finer, denser, and more extensive than in fortipes. 



Head, except for the ocellar triangle and a dark patch behind the antenna] in- 

 sertions, and the mesoscutum, except for a dark patch in front, red ; hind femur 

 almost yellow, except for a dork apical tip ; hind tibia more reddish than its femur ; 

 tergite 1 obscure testaceous and contrasting with the black 2nd tergite ; gaster 

 (Text-fig. 338) .......... pelides sp. n. 



Brazil: Nova Teutonia, viii. 1035, 1 o # the TYPE, {Plaumann). Type in the 

 British Museum. 



Monobasic. 



BULUKA deSaeger 



Buhtka de Saeger, 1948 : 64. 



I have no doubt that I have correctly recognised this genus ; de Saeger has given 

 an excellent figure of it. 



The genus is remarkable only because of the structure of the gaster and certainly 

 belongs to the Microgasterinae and not to the Sigalphinae in which subfamily de 

 Saeger, while fully aware of its Microgasterine features, put it. 



In my opinion Bidiika is not far removed from Protomicroplitis in its widest sense 

 and, within this genus, shows affinity perhaps with the connexus-group because of the 

 smooth vertex and temples and the shortness of the first abscissa of the discoideus. 



There are two males in the British Museum collection that I have provisionally 

 identified as Buluka straeleni. 



Buluka straeleni de Saeger 



Buluka straeleni de Saeger, 1948 : 65. 



o*. Front and middle legs entirely yellow ; hind tibia yellow on about apical half ; hind 

 femur dark brown virtually throughout. Fore wing crossed by a dark band beneath the stigma ; 

 this band is darker on the stigma side of the wing. Two basal tergites yellow. 



Head above smooth, shining, with faint satin-like sheen. Ocelli in a low triangle. Apical 

 segment of labial palpus fully as long as the two preceding segments together. 



Mesoscutum dull, densely and evenly rugose-punctate to reticulate-punctate posteriorly. 

 Disc of scutellum dull, densely reticulate-punctate, its rugose tip interrupting the posterior, 



6i Xanthomicrogaster fortipes Cameron 191 1: 325.
