Var. 2 • Head, mesothorax, and abdomen entirely testaceous ; 

 antenna? 25-jointed. Nervure dividing the 1st cubital areolet from 

 the praediscoidal extremely faint. An old specimen in Fitch's 

 collection. Somewhat doubtful, but placed here provisionally. 



Antennae $ as long as the body, filiform, 25 — 26-jointed, black, 

 with the 1st joint testaceous. Stemmaticum fuscous. Nervure 

 dividing the 1st cubital and praediscoidal areolets weak and sub- 

 interrupted ; cubital nervure subobsolete. Thorax black ; rneso- 

 thoracic sutures converging into a punctate depression. Scutellum 

 smooth, preceded by a transverse fovea nmch shorter than itself. 

 Metathorax punctato-rugulose, not areated, truncated, and with an 

 oblong excavation behind. First abdominal segment slender, 

 tuberculated in the middle, at the apex three times wider than the 

 petiole, finely striated longitudinally ; black, the petiole pale at the 

 base ; the rest of the abdomen oblong-ovate. Antennae of the $ 

 stouter, longer than the body, 28 — 29-jointed, the 1st joint black ; 

 in one $ the antennae are only 23-jointed. 



Described from two females, four males. Rather 

 common throughout the country. I have repeatedly 

 found the ? , and in 1885 captured both sexes in a wood 

 at Nunton. Capron has taken six females at Shiere. 



2. Perilitus strenwus, n. s. 



Niger, antennarum radicula, ore, orbitis, rufo-testaceis, vel 

 orbitis interdum nigris. Pedes 4 anteriores testacei ; femora inter- 

 media basi fusca ; postici picei vel fusco-testacei tibiis apiccm 

 versus obscurioribus ; tarsi omnes nigri. Abdominis segmenta 

 2 — 3 picea. Alae fere hyalinae, stigmate, nervis, squarnulis, pallide 

 fuscis ; areola radialis longior et latior quam in specie praecedente. 

 Scutellum laeve, fovea ante basin transversa, breviore quam ipsum, 

 iDstructum. Petiolus in longitudinem striolatus, utriusque sexus 

 latior quam in P. rutilo ; feminae duplo latior quam maris. Terebra 

 dimidia abdominis longitudine. 



Black ; radicle of the antennae, mouth, orbits, and cheeks, rufo- 

 testaceous ; or the orbits concolorous. Four anterior legs testa- 

 ceous ; middle femora fuscous at the base ; hind legs piceous or 

 fusco-testaceous, their tibiae darker towards the tips ; all the tarsi 

 black. Abdominal segments 2 — 3 piceous. Wings nearly hyaline, 

 stigma, nervures, and squamulae pale fuscous ; radial areolet longer 

 and broader than in the preceding species. Scutellum smooth, 

 preceded by a transverse fovea much shorter than itself. Petiole 

 longitudinally striolated, in both sexes broader than that of rutilus ;
