CHALCIDOIDEA BRED FROM GLOSSINA MORSITANS IN 



NORTHERN RHODESIA. 



By James Waterston, B.D., B.Sc, 

 Imperial Bureau of Entomology, London. 



In connection with investigations into the hfe-history, etc., of Glossina ynorsiians 

 in Northern Rhodesia, special efforts have recently been made to secure parasites 

 of the fly. As a result, a considerable number of Chalcidoids have been bred from 

 puparia collected between August and December of last year at Kashitu (LI. Lloyd) 

 and Mwengwa (R. A. F. Eminson). These interesting Hymenoptera have now been 

 forwarded to the Imperial Bureau of Entomology by Mr. Lloyd, Chief Entomologist 

 in Northern Rhodesia, with the parasitised puparia and some relevant notes. On 

 this material the present report is based. The collection contains three species, 

 representing as many widely separated groups in the superfamily Chalcidoidea. 

 Two believed to be new are described below, the types being deposited in the 

 British Museum. 



Family Chalcididae. 



Genus Stomatoceras, Kirby (1883). 



Stomatoceras, Kirby, Jouin. Linn. Soc. Lond., xvii, no. 98, p. 62, PI. iv, figs. 21-23 



(1883). 

 Genotype* Halticella'f (sic) liberator, Walker, Trans. Ent. Soc. Lond. (3) i, p. 361 



(1862). 



In erecting Stomatoceras, Kirby failed to note the characteristic armature of the 

 propodeon.J This omission he later supplied (Journ. Linn. Soc. Lond., xx, no. 116, 

 p. 36, 1886) ; nevertheless, Ashmead (Mem. Cameg. Mus., p. 255, 1904) includes 

 Stomatoceras in the section of the Haltichellinae in which the " metathorax " 

 (i.e., propodeon) is " normal, without projections," and in this error he is 

 apparently copied by Schmiedeknecht (Wytsman's Genera Insectorum, Chalcididae, 

 p. 49, 1909). Schulthess (Bull. Soc. Vaud. Sc. Nat., xxxv, p. 251, 1899) treats 

 Stomatoceras as a subgenus of Haltichella, but the group included here deserves, 

 I believe, full generic rank. The § $ may be separated by the following characters : — 



Antennae slender, 11 (13) jointed, the divisions of the last joint generally requiring 

 clearing in potash for demonstration. Scutellum sharply bidentate, with no median 

 furrow and diiTering in sculpture from the mesonotum only in the rather more 

 closely set puncturation. Propodeon with one (sometimes only slightly raised) 

 projection before the crescent stigma and two well developed, behind, on the ridge 



* The genotype, Stomatoceras liberatory Walker, in the British Museum is from Port 

 Natal (Guienzius). The eleventh joint of the left antenna (mounted in balsam) is 

 distinctly twice divided. 



t Spinola (1811) named his genus Haltichella; Walker wrote Halticella, which is 

 preferable, but the change is inadmissible. 



X In the Oxford Dictionary it is pointed out that Newman's original spelling — 

 propodeon — is the correct Latinised form of this term, and not propodeum.
