CHALCIDOIDEA BRED FROM GLOSSINA IN THE NORTHERN 

 TERRITORIES, GOLD COAST. 



By James Waterston, B.D., B.Sc, Lieut. R.A.M.C. 



The material on which the following report is based was received by the Imperial 

 Bureau of Entomology some months ago, but without any note as to the host 

 attachment of the examples forwarded or any other indication of their special 

 importance. For this reason the two species of Chalcids recorded below remained 

 unworked for some time. A more recent letter from Dr. J. J. Simpson disclosed 

 the interesting fact that both had been bred from puparia of Glossina ; and although 

 I am unable at present to deal fully with them, it seems advisable to publish some 

 notes and a preliminary description of one species which seems certainly new. 



Dirhinus inflexus, sp. nov. 



5. Head, thorax and abdomen black ; the flattened setae on head (superiorly) 

 and thoracic notum yellow, but whitish on genae. Fore wings brown-tinted, veins 

 a little darker. Fore and mid coxae and hind legs (except the tarsi) black ; fore

and mid legs otherwise brown ; hind tarsi the same but paler. Tip of ovipositor 

 sheath brown. Antennae brown, more or less infuscated, especially on the funicle, 

 but paler at the tip. 



Length, 3J mm ; alar expanse. 5J mm. 



Type $ in the British Museum. 



Gold Coast: Larabanga, N. Territories, 1-6. vii. 1916 {Dr. J. J. Simpson). 



D. inflexus is closely related to D. giffardi, Silv. (Boll. Lab. Zool. Portici, viii, 

 p. 128, figs, liii-lvi, 28th Nov., 1913), and D. elirhorni, Silv. {ib., p. 132, figs, lvii-lviii), 

 both of which were described from Southern Nigeria, where they attack fruit-flies 

 of the genus Ceratitis. In D. giffardi the wings are nearly hyaline, the antennae
