1919] Bequaert — Nearctic Psammocharids of Genus Aporinelltis Banks 119 



Propodeum with pronounced apical emargination and acute lateral 

 angles. Legs slender as compared with A. fasciatus, the femora 

 and tibiae hardly swollen. Comb of the fore tarsi feeble, com- 

 posed of 5 or 6 short bristles, the longest of which are less than 

 half the length of the fore basitarsus and about the length of the 

 second tarsal joint. Fore wings with the second cubital cell com- 

 paratively short, slightly over 1| as long as broad. Transverse 

 median of the hind wings ending much before the base of the 

 cubitus. 



Head mostly and thorax entirely black; anterior margin of 

 clypeus, mandibles except their apical teeth, and first antennal 

 joint below, more or less reddish. Abdomen with the three first 

 segments bright ferruginous red; the apical margin of the fourth 

 tergite faintly reddish; the remainder black. Legs red; the 

 coxae, trochanters, extreme tips of femora and tibiae, tibial spurs 

 and larger part of the tarsi, black; the basitarsus and under side 

 of trochanters on middle and hind legs suffused with red, and a red 

 spot on the under side of the hind coxae. Tarsal comb and erect 

 bristles of tibiae and tarsi black. Wings subhy aline; fore wings 

 with a spurious cloud on the basal vein, their apical quarter 

 infuscate. 



Tegument impunctate, very shining. Body entirely without 

 sericeous pile, clothed in a feeble grey pruinosity, which is a little 

 more pronounced on the propodeum. No trace of abdominal 

 silvery fasciae. A few erect hairs on the clypeus, mandibles, and 

 two apical segments of the abdomen. 



Described from one female taken at Stony Brook Reservation, 

 near Boston, Mass., July 12, 1919; it was sunning itself on a stony 

 woodroad, after the usual Psamraocharid manner. 



This species is very striking in its coloration and its shining 

 integument; its closest relative is undoubtedly the species de- 

 scribed below as A. banksi. 



Aporinellus banksi sp. nov. 



Female. Length 6.5 mm. 



Head comparatively broader than in A. fasciatus, much broader 

 than the thorax. Inner margins of the eyes subparallel near the 

 clypeus, curved outwardly about the middle of the face, then 

 feebly converging towards the vertex which is distinctly narrower
