the base of the antennfe by a distance nearly equal to twice 

 the length of the scape, third joint of the flagellum almost 

 equal to the second. Posterior ocelli as far from the eyes 

 as from each other. Head and thorax very finely and 

 closely punctured, meso[)leur8e horizontally striated on the 

 upper portion, finely punctured on the lower portion^ the 

 carinse as in ciliatus ; the transverse groove at the base of 

 the scutellum foveolate, but very narrow and indistinct 

 in the middle. Median segment coarsely longitudinally 

 striated, less coarsely on the basal area than elsewhere. 

 Abdomen very finely punctured, the basal segment short, 

 about half as broad at the apex as the second segment ; 

 pygidial area elongate-triangular, very narrowly truncate at 

 the apex. Fore tai'si very strongly ciliate, the ajjical joint 

 much swollen, the pulvilli large ; hind tibiae spinose ; inter- 

 mediate tibite with two strong apical spines, the one much 

 longer than the other. Second abscissa of the radius very 

 short, not more than one-eighth of the length of the third, 

 cubitus of the hind wing originating at a distance beyond 

 the transverse median nervure slightly exceeding the length 

 of that nervure.

This is closely allied to perkinsi and ciUatuf;, but the 

 sculpture of the median segment is very different. 



Arpactus spryi., sp. n. 



S . Niger : scapo, flagello articulo primo, pronoto postice, callis 

 hiimeralibus, segmentis dorsalibus 1-5 linca transversa apicali, 

 femoribus anticis apice subtus, tibiisqiie anticis et intermediis 

 macula basali flavis ; tegulis, femoribus apice, tibiis tarsisquo 

 ferrugineis ; alis hyalinis, venis fuscis. 

 Long. 9 mm. 



cJ . Clypeus broadly truncate at the apex ; eyes strongly 

 convergent towards the clypeus, separated at the base of 

 the antennae by a distance about half as great again as the 

 length of the scape ; posterior ocelli much farther from each 

 other than from the eyes. Apical joint of the flagellum 

 very strongly curved, with a small spine at the base, scarcely 

 longer than the penultimate ; joints 8-11 slightly produced 

 at the apical angle, but not sufficiently to form a spine. 

 Pronotum narrow and transverse ; mesopleurse with a 

 distinct vertical carina in front, the mesosternum separated 

 from the raesopleurse by a carina, the upper part of the 

 mesopleurEe horizontally striated, the lower part rugulose.
