I am able to give a description of a third species, having an 

 oblique cross nervure in the lanceolate cellule, a species too which is 

 very distinct from the others, differing widely from them in the color- 

 ation of the abdomen and less. 



It was taken during an excursion which I made with Dr. Sharp 

 to Crickshope Linn, near Thornhill, on the 14th of June. Neither 

 the locality nor the day was favourable for collecting purposes ; but, 

 fortunately, when we were at the foot of the waterfall the suu 

 shone brightly, bringing out insects, and it was by sweeping the ferns 

 on the steep sides of the bank close to the water that my specimens 

 were obtained. I propose to call it 



STEONGTLOaASTER ShARPI, Sp. U. 

 Black ; the clypeus, palpi, tegulse, edge of pronotum, the apex of the last ab- 

 dominal segment above, and legs, yellowish-white ; the apex of the posterior tibiae 

 and the posterior tarsi fuscous. Wings hyaline ; the costa pale, and the stigma dark 

 fuscous. The clypeus is broadly incised, the labrum fuscous, the mesonotum and 

 head are slightly opaque, faintly punctured, the pleurae, sternum, and abdomen more 

 shining and impunctate. The dorsum of abdomeu is keeled in the middle ; its apex 

 is obtuse and truncated ; the saw does not project. The wing cellules are broader 

 than in the other species, compared to the length ; the marginal nervure is curved, 

 and received before the middle of the third sub-marginal cellule. The antennae are 

 shorter than the tliorax and abdomen, and of the usual form. The coxae, trochanters 

 and knees are paler tlian the rest of the legs. Length, 2t, alar exp. 'i>\ lines. 



It is the smallest of the European species, being half a lino shorter 

 than 8. delicatulus. I have only seen the ? .

 others desci-ibed by Eversmann in the same paper. From a note in the Zuol. Rec. f'lr IbVO, these 

 omissions have, I understand, been pointed out by Ballion in Bull. Mosc, t. 42, pp. 441 — 448.
