392 JAMES WATERSTON. 



The claws are minute. The first fore tarsal is nearly two-thirds the first hind tarsal 

 joint. All the legs are long ; the extended mid leg about three-fourths of the length 

 of the insect. Abdomen : all the tergites sclerosed and with the proportions given 

 in the sketch ; the first tergite medianly shallowly incised ; the others probably 

 straight-edged. Anteriorly the pubescence is sparser, but dense posteriorly (from 

 the fourth segment). Ovipositor slightly protruding. 



Length about 5 mm. 



Type a $. 



Nyasaland : Monkey Bay, Lake Nyasa ; bred from puparium of Glossina 

 morsitans, 30. v. 15 (Dr. W. A. Lamhorn). 



Family: EULOPHIDAE. 

 Syntomosphyrum glossinae, Wtrst. 



S. glossinae, Waterston, Bull. Ent. Res., v, pt. 4, p. 365, figs. 14-16, and ibid, vi, 

 pt. 1, p. 81 (1915). 



This species has now been shown by Dr. Lamborn to be a hyper-parasite of Glossina 

 morsitans through Mutilla glossinae, Turn. 



Nyasaland : Monkey Bay, Lake Nyasa ; 13 $ $ bred from a puparium of 

 Glossina morsitans, 17.vi.l5 [Dr. W. A. Lamhorn). 



These are presumably part of the parent stock from which Dr. Lamborn conducted 

 the breeding experiments noted below. The numbers of each sex detailed are those 

 actually received by the Bureau. 



" These tiny Chalcids were bred from two female parents which with the male 

 parents also emerged from the same pupa. Coitus 20. vi. 15." 



125 a. Tsetse pupa parasitised by Mutillid on 17.vi.l5. Chalcid at work on it on 

 23. vi. Offspring emerged on 27.vii, eleven in all. 

 11 ?? (34 days). 



125 h. Pupa parasitised by Chalcid on 24. vi; offspring, eighteen in all, emerged 

 on 27.vii. 

 15 $ 2 (33 days). 



125 c. Pupa operated on by Chalcid on 25. vi. and offspring — thirteen — emerged 

 on 29.vii. 

 13 ? (34 days). 



125 d. Pupa operated on by Chalcid on 27. vi. and offspring — thirty-six — emerged 

 on 29.vii. 

 7 cJ, 24 ? (32 days). 



125 e. Pupa which was then chipped and showed the cocoon of the Mutillid, was 

 operated on by the Chalcid on 28. vi., and the Chalcid's offspring, 29 in all, 

 emerged on l.viii. 

 1 (?, 28 ? (34 days). 



125 /. Pupa was operated on by the Chalcid on 25. vi., and the offspring, numbering 

 32, came out through the holes on 2 . viii. 

 1 cJ, 31 Q (38 days).
