HEMIPIMPLA. 187 



This genus is certainly allied to Epiurus in its emarginatu 

 clypeus, lobate $ claws, strongly uneven abdomen, subcircular 

 metathoracic spiracles and short antennae. Its species are very 

 beautiful (cf. Distant, Nat. in Transvaal, 1892, p. 227). 



Ashrnead characterised his genus (loc. cit.) as having : The 

 areolet oblique and rhouiboidal ; the first recurrent nervure of the 

 lower wings intercepted very far above its centre ; the tarsal claws 

 lobate strongly at their base, and not pectinate ; the tnetathorax 

 smooth, with no trace of either carina? or area3 ; the second to 

 fifth segments with deeply impressed and laterally continuous 

 sulci at both base and apex ; and finally, having the clypeus setni- 

 circularly emarginate at its apex and not discrete from the face at 

 its base. But elsewhere (lib. cit. p. 55) he distinctly says that the 

 clypeus is discrete from the face, and it is entirely upon the sepa- 

 ration of the clypeus that Hemipimpla differs from Eryihropimpla, 

 since in all other particulars, such as the glabrous metaiiotum, 

 elongate spiracles, terebra longer than abdomen and basally lobate 

 claws, it very perfectly agrees therewith. It is obvious, I think, 

 that Ashmead did not really know Hemipimpla, and equally 

 obvious that his table is herein defective. Cameron has further 

 complicated the matter by redescribing the genus under the name 

 TrichiotJiecus. 



The superficial resemblance of some of the following species to 

 the Braconid genus Myosoma, found in the Malay Archipelago and 

 probably in India, is very remarkable.* 



Table of Species. 



1 (4) Abdomen testaceous, closely and con- 



nuently punctate, at least discally. 

 '2 (3) Basal segment distinctly punctate and ex- 



carinate ; alar infnmescence broader and 



darker testacea, Cam., p. 188. 



'} (2) Basal segment impimetate and strongly 



biccirinate ; alar infnmescence narrower 



and paler cftffi-a, Sauss., p. 189. 



4 (1) Abdomen black, very deeply and somewhat 



sparsely punctate throughout. 



5 (6) Stigma black and the whole wings ni- 



grescent ntffosa, de G., p. 190. 



6 (5) Stigma and wings, except apices of latter, 



testaceous ariana, Cam., p. 192. 



* It has been suggested (Journ. Str. Br. Royal Asiatic Soc. 1903, p. 137) 

 tnat Pinylo viridipennis, Smith (Proc. Linn. Soc., Zool. 1860, suppl. p. 64) J, 

 described from Celebes, probably belongs to the present genus ; no doubt can 

 remain that this is the case, and but little can be entertained that it is the 

 alternate sex of Cameron's Trichiothecus rnjiceps. I have not entered it in 

 the synonymy, however, since I have had the opportunity of examining only 

 the single example, labelled " Pimpla viridipennis, var. a; Mak[assar]," in 

 the National Collection, and not the type, which is to be sought in the Wilson 

 Saunders Collection at Oxford.
