CHALCIDOIDEA BRED FROM GLOSSINA MORSITANS IN NYASALAND.

Since my previous report on the Chalcidoid parasites of Glossina appeared (Bull. 

 Ent. Res., vi, pt. 1, p. 69, 1915) a second important collection has been received by 

 the Imperial Bureau of Entomology from Dr. W. A. Lamborn, their Entomologist 

 in Nyasaland. In this materal five species are represented, of which three here 

 described are believed to be new. The status of the remaining two, Stomatoceras 

 micans, Wtrst., and Syntomosphyrum glossinae, Wtrst., may now be regarded as 

 established, in the former case from its recurrence on the same host in two widely 

 separated localities, in the latter from Dr. Lamborn's valuable notes. Six species of 

 Chalcidoids have now been bred from puparia of Glossina spp., and all from G. morsitans. 



Family CHALCIDIDAE. 

 Genus Haltichella, Spin. 



Haltichella, Spinola, Ann. Mus. Hist. Nat., Paris, xvii, p. 148 (1811). 



Genotype, H. (Chalcis) pusilla, Fabricius, Mant. Ins., i, p. 272, (J $ (1787). 



This genus, as I understand it, includes forms w^ith the post-marginal equalling or 

 exceeding the marginal ; the wings sometimes tinted, but generally without definite 

 bands or large spots ; the lower edge of the hind femur undulated, denticulate up to 

 three-fourths from the apex (or more shortly), but without a major tooth or prominent 

 lobe. Scutellum bidentate ; propodeon unarmed ; i.e., the single angle behind the 

 spiracle upturned and inconspicuous. 



The length of the post-marginal is a character of great importance for arranging 

 the Haltichellines, but one which it is occasionally hard to estimate ow^ng to the 

 infuscation of the costa, which may resemble a continuation of the nervure. In such 

 cases if the wing is looked at from behind edgeways, and highly magnified, one can 

 generally see a distinct difference in the thickness of the costa, indicating the demar- 

 cation of the post-marginal. But it is best to examine carefully a wing mounted in 

 balsam. With the two new species which are here assigned to Haltichella and 

 Stomatoceras (Centrochalcis) respectively, Dr. Lamborn has enclosed another very 

 distinct Haltichelline, not, however, bred from Glossina. This Hockeria is described 

 in a paper (p. 419) immediately following the present one. To facilitate comparison, 

 however, the femoral edge and neuration of the Hockeria have been illustrated here 

 (figs. 1 and 2). 



Haltichella edax, sp: nov. 



(J. Head, antennae and thorax black ; tegulae dark brownish fuscous. Abdomen : 

 first visible segment broadly black basally, the dark area extending medianly through 

 the second segment and into the third ; at the sides posteriorly segment i. is trans- 

 parent dark brown, the same colour flanking the black area on segments ii. and iii.

 coxae black ; mid coxae black, but lighter on the apical one-fourth ; hind coxae 

 dark clear red, black only on the upper basal half ; legs otherwise reddish, paler on
