IX. Descriptions of new genera and species of 

 Hymenoptera. By P. Cameron. 



[Read April 4th, 1883.] 



In this paper I have given descriptions of new species of 

 Hymenoptera from the Sandwich Islands, Brazil, and 

 Britain. For the Sandwich Islands species I am in- 

 debted to the Bev. Thomas Blackburn, who has done 

 such good work in investigating the entomological fauna 

 of these Isles. As our esteemed colleague has now left 

 the Sandwich Islands, there is no chance of my receiving 

 any more specimens ; so I purpose, in a future paper, 

 giving a complete catalogue of the Hymenoptera known 

 to inhabit the Archipelago.

Epitranus lacteipenni's, n. s. 



Dark reddish testaceous ; the head behind, more or 

 less of the lobes of the mesonotum, pleura, sternum, 

 metanotum, petiole for the most part, abdomen more or 

 less at the sides and above, coxae and femora in the 

 middle, blackish. Antennae not much longer than 

 thorax, becoming very gradually thickened towards the 

 apex, which is sharply conical ; the joints of the flagellum 

 blackish at the apex. Head obsoletely punctured, covered 

 with scattered silvery white short hairs ; hind ocelli 

 situated on the edge of the head behind. Thorax 

 coarsely punctured : in the centre of the mesopleura is 

 a shining semi-oblique line ; in front of this line the 

 pleura is obliquely striated. The scutellum is margined 

 behind, the border shortly projecting. Metanotum 

 reticulated, finely punctured. Petiole carinated at the 

 side, longitudinally striated. The 2nd abdominal seg- 

 ment is longer than the petiole ; its basal half is smooth 

 and shining, the apical finely punctured ; the posterior 

 coxse are not much shorter than the femora, which are 

 somewhat alutaceous, and, with the coxae, are covered
