transverse ; the sides of the metathorax are said to be pro- 

 duced into " sharp tubercles/' here broadly rounded ; the 

 cmargination is said to be "longitudinally striated/' here 

 there are only three stout irregular keels. If the figure of 

 ilus (Journ. Bomb. Nat. Hist. Soc. 1893, pi. i. fig. 7) is 

 correct, then ilus differs from our species in having the first 

 cubital cellule on the top distinctly shorter than the second, 

 whereas in our species it is the second which is distinctly 

 shorter than the first. In Hookeri the third transverse 

 cubital nervure is not broadly rounded^ but has an oblique 

 straight slope above.

Long. 14 mm. 



Antennae with the apical three joints black; the scape 

 covered with short golden pubescence. Head shining, the 

 cheeks and the clypeus sparsely covered with a short golden 

 pile ; above there is a broad black band extending from 

 behind the ocelli to near the base of the antennae, where it is 

 divided in the middle by a tubercle which has an elongated 

 fovea in the middle above ; there is a narrow furrow below the 

 eyes, which distinctly converge above ; the hinder ocelli are 

 separated from the eyes by the same distance they are from 

 each other. Apex of clypeus rounded; mandibles black, ferru- 

 ginous at the apex; palpi fulvo-testaceous. Pronotura broadly 

 ferruginous behind, its sides there with an oblique slope to 

 the middle ; in the centre of the mesonotum behind is a large 

 mark, slightly narrowed towards the apex, its sides projecting 

 at the base. Scutellum flat, ferruginous above, except 

 nai'rowly at the apex. JNIedian segment with a gradually 

 rounded slope, thickly covered with peach-coloured pubes- 

 cence and sparsely with black hairs ; the apex is indistinctly 

 transversely striated. Legs ferruginous ; the coxae, tro- 

 chanters, and base of femora black ; the apices of the joints 

 of the posterior tarsi and the apical joint of the middle 

 and posterior entirely black ; the tooth on the middle of the 

 claw is distinct. Wings uniformly deep violaceous; the first 

 cubital cellule is shortly but distinctly longer than the 

 second above ; the first recurrent nervure is received near 

 the second transverse cubital nervure, the second near the 

 base of the apical third of the cellule ; the transverse basal 

 nervure is interstitial. Abdomen deep velvety black, shining ;
