Australian Braconidae in the British Museum. 99 



a carina runs to the apex of the segment, the surface of the segment 

 shining, with irregular rugae; second and third sutures crenulate. 

 Anterior angles of the third tergite divided from the rest of the 



segment by a erenulated groove, the segment with a median longi- 

 tudinal carina, the base longitudinally striated; the remaining 

 segments smooth. First abscissa of the cubitus almost straight; 

 the first discoidal cell much higher on the basal than on tin- recurrent 

 ne rv ure.

The scheme of colouring is fairly common among- the 

 larger Braconidae of the Austro -Malayan region and extends 

 to the tropical districts of Queensland. This species is 

 somewhat allied to palpalis, Szep., which has the third 

 and fourth joints of the palpi broadly flattened, and to 

 medianus, Szep., which has the face rugose. 



I doubt if the genus Merinotus can be separated from 

 Sigalphogastra, Cam., which has priority; but the male of 

 Sigalphogastra has only five visible tergites, the fifth being 

 very large ; in M. xanthocephalus the . male shows six 

 tergites, the fifth very large and the sixth small. In both 

 the mouth parts are somewhat elongate. The female of 

 Sigalphogastra is still unknown. The male of the common 

 South African species Merinotus bellosus, Sin., has six 

 tergites visible, the fifth not unusually large and the sixth 

 not very small. Until larger collections are available it 

 is perhaps better not to sink the name Merinotus.
