aber, ob die Punkte dicht oder zerstreut stehen. An dem mir einzig vorliegenden Stücke 

 von dispersa finde ich auch das Gesicht nicht runzelig punktirt und ist dispersa nur 

 5 Mm., nicht 6*5 Mm. lang. Als Unterschied lasse ich auch Cameron's Bemerkung auf, 

 dass der Scheitel nicht st) stark punktirt ist wie das Gesicht, während bei dispersa der- 

 selbe nicht im mindesten weniger grob punktirt ist als das Gesicht. Von marginata Cam. 

 unterscheidet man dispersa am leichtesten an dem polirt glatten Hinterleibstiel, an dem 

 matten, nicht runzelig punktirten Gesichte und an den nicht umrandeten Augen.

Antennae with the scape nearly as long as the third and fourth joints united; the 

 third Joint longer than the fourth, and nearly three times the length of the second Joint. 

 Face densely covered with stiffsilvery-white pubescence, rugosely punetured, nearly trans- 

 verse. Frons denselv pilose, the pile not so long as that on the face but closer, keeled 

 down the centre, rugosely punetured; the vertex is not so strongly punetured and has 

 the punetures more widely separated. Collar almost transverse, but projeeting a little in 

 the middle. Mesonotum shining, the middle lobe marked with large distinctly separated 

 punetures; the lateral lobes impunetate, a wide shallow furrow down the centre; para- 

 psidal furrow narrow, moderately deep. Scutellum punetured. Pleurae rugosely pune- 

 tured, the punetures running into reticulations; a large shining impunetate space below 

 the fore wings, and a smaller one below the hind wings. Metathorax rugosely punetured. 

 Petiole double the length of the metanotum, smooth, shining, impunetate. Hind coxae 

 punetured; spurs reaching to the middle of the metatarsus, the latter scarcely so long as 

 the following three joints united. The four anterior legs are more or less obscure 

 brownish in front; the anterior trochanters are almost entirelv white, the posterior pair
