DORYCTES. 383 



the scape covered with a long pile, obscurely striated ; third joint elongate, longer than 

 the fourth ; the other joints so closely amalgamated as to be indistinguishable. Head 

 with the face below the antennas coarsely rugose ; vertex shining, impunctate, depressed 

 behind ; a broad furrow (narrowed at either end) above the antennae, but not reaching 

 to the top of the depression ; face covered with long fuscous-black hair ; eyes oval, 

 margined, the head considerably developed behind them, but not projecting ; ocelli 

 surrounded by a furrow ; mandibles piceous at the base ; palpi black, long, pilose. 

 Thorax shining ; metathorax obscurely shagreened, showing a gradual slope to the 

 apex; mesonotum with the middle lobe clearly separated from, and raised a little 

 above and produced considerably in front of, the lateral lobe, and much broader in 

 front than behind ; the mosonotal sutures distinct, curved in front, and obscurely 

 shagreened ; the oblique furrow on the mesopleurae wide and moderately deep ; a much 

 shorter, striated furrow on the mesosternum and a long and very narrow one on the 

 metapleurae, a wider furrow running down the metanotum. Abdomen scarcely one 

 half longer and not much broader than the thorax; petiole flattish above, except at the 

 apex, somewhat strongly longitudinally striated, with a narrow aciculated furrow along 

 either side above, and a lateral (slightly wider) perpendicular furrow lower down, smooth 

 at the apex, aciculate at the base ; the second segment longitudinally striated on either 

 side at the base, with a narrow transverse furrow, the centre aciculated. Terebra stout, 

 the sheaths pilose. Tibiae and tarsi densely pilose, the coxae and trochanters sparsely 

 clothed with long black hair. Wings long and narrow, the apical third paler ; an 

 oblique narrow hyaline cloud in the first cubital cellule ; the recurrent nervure almost 

 interstitial ; the second cubital cellule short, scarcely twice the length of the third.

Antennae thin, filiform, longer than the body, densely pilose ; third joint a little longer 

 than the fourth. Head rugose in front, opaque ; vertex shining, impunctate ; consider- 

 ably depressed above the antennae, the depression transversely striated ; the ocelli 

 surrounded by an oblong furrow, which is incomplete behind ; the central furrow 

 wide, shining, moderately deep. Thorax shining, impunctate ; metanotum obscurely 

 shagreened, especially at the sides, with a narrow keel running down the middle, the 

 keel bifurcating at the centre and there forming an elongated area. Petiole shining, 

 impunctate ; the sides depressed at the base, the raised part having a keel along the 

 sides; the furrow narrow and along the extreme edge. The other segments also 

 smooth, shining, impunctate, without furrows or depressions. 



Differs from D. strongylogaster in being smaller ; the antennae shorter, much more 

 densely pilose; the frontal furrow longer, and reaching nearly to the ocelli; the
