o£ the other species of the group, the cilia of long hairs on 

 the ventral segments is missing. The first abdominal seg- 

 ment is much longer and more slender than in any other 

 species of the group except consuetipes. The anteunal 

 structure resembles spryi, but the peculiarities are rather 

 more developed than in that species. 



Arpactus consuetipes, sp. n. 



J . Niger ; anteimis, tegulis, femoribus apice, tibiis tarsisque ferru- 

 gineis ; pronoto linea transversa, callis humeralibus, scutello 

 macula parva, segmentisque abdomiualibus prirao, secundo, quarto 

 quintoqne fasciis angustis apicalibus flavis ; segraentis duobus 

 apicalibus pallide ferrugiueis ; alls hyaliuis, veuis ferrugineis. 



Lo7]g. 9 mm. 



cJ . Eyes very strongly convergent towards the clypeus, 

 separated at the base of the antenna by a distance not quite 

 equal to the length of the scape. Apical joint of the fla- 

 gellum longer than the penultimate, very feebly curved. 

 Mesopleurse horizontally striated on the upper portion. A 

 transverse foveolate groove at the base of the scutellum ; 

 postscutellum and basal area of the median segment coarsely 

 longitudinally striated, the doi'sal surface of the median 

 segment on the sides rugose, separated from the sides of the 

 segment by distinct carinse, the sides of the segment rugose- 

 striate. First abdominal segment narrowed to the base, at 

 the apex only one-third of the breadth of the apex of the 

 second segment. Fourth and fifth ventral segments with 

 distinct apical cilise. Fore tarsi not ciliated ; intermediate 

 tibise with two equal apical spines ; hind tibiae moderately 

 spinose. The neuration is similar to spryi, but the spurious 

 vein branching from the first transverse cubital nervure is 

 not clearly defined, and on one side the fir&t transverse 

 cul)ital nervure is incomplete, not reaching the radius.

This belongs to the ciliatus group ; the first abdominal 

 segment is more slender than in other species of the group.
