EYANIA. 429 



Antennae with the scape a little shorter than the third joint, the latter nearly equal 

 in length to the fourth joint ; the middle and apical joints slightly dilated at the apex. 

 Head transverse in front, rugosely punctured, the face covered with long silvery-white 

 hair ; a keel down the centre of the front. Mesonotum transverse, shining ; the middle 

 lobe bearing large deep punctures, the lateral lobes slightly shagreened. Parapsidal 

 furrows deep, wide ; the furrow along the sides crenulated. Scutellura rugosely punc- 

 tured. Pleurae rugosely punctured, the punctures running into reticulations ; the meso- 

 pleurae in front in the middle impunctate. Metathorax coarsely rugosely punctured. 

 Petiole shining impunctate, double the length of the metanotum. Pleurae and meta- 

 thorax densely covered with rather long white pile ; a fuscous pile on the mesonotum. 

 The petiole sparsely pilose ; the apex of the abdomen above sparsely covered with short 

 greyish pile. Coxae thickly, the femora more sparsely, covered with a silvery-white 

 pile ; tibiae and tarsi with a short thick fuscous pile. Hind coxae somewhat coarsely 

 punctured; tibiae and tarsi covered with a few stiff bristles. Hind spurs reaching 

 nearly to the middle of the metatarsus, the latter as long as the following three joints 

 united. Claws apparently simple. The anterior legs are more or less obscure white 

 in front. The transverse medial nervure is interstitial.

Antennae thick, slightly attenuated towards the apex ; the scape as long as the third 

 and fourth joints united ; the third joint three times the length of the second, and a little 

 longer than the fourth joint. Head rugosely punctured, the front a little depressed, a 

 keel running down its centre from the ocelli, the space on either side of the keel 

 above the antennae being finely punctured or shagreened. Face almost transverse, 

 keeled on either side. Mesonotum transverse in front ; rugosely punctured, except the 

 inner side of the lateral lobes. Parapsidal furrows moderately deep ; there is no lateral 

 furrow. Scutellum rugosely punctured. Pleurae rugosely reticulated, except beneath 

 the wings on the mesopleurae, where there is a large shagreened space. Metathorax 

 coarsely rugosely reticulated. Petiole impunctate, nearly twice the length of the 

 metanotum. Hind coxae indistinctly punctured, shining ; hind spurs reaching nearly 

 to the middle of the metatarsus, the latter as long as the following three joints 

 united. 



The male has the scape longer and thinner than the female ; the third joint is 

 longer compared to the fourth ; and, if anything, the thorax is more closely punctured.
