PTEROMALIDAE OF N.W. EUROPE 269 



dorsally shiny and nearly smooth, except the strip corresponding to the collar, which is aluta- 

 ceous and thickly clothed with dark subadpressed hairs, the latter arising from small tubercles ; 

 laterally the sclerite is lightly reticulate and nearly bare. Mesoscutum about twice as broad as 

 long, uneven, intricately and finely reticulate, rather thickly clothed with dark hairs which are 

 only slightly outstanding, these hairs arising from small tubercles ; notauli very deep and 

 sharply defined. Axillae rather shiny, alutaceous, fairly thickly clothed, except along their 

 outer edge, with dark hairs like those of the mesoscutum. Scutellum 1 -25 times as long as 

 broad, strongly convex, moderately shiny, finely intricately alutaceous, clothed, except the 

 frenum, with numerous slightly outstanding fuscous hairs ; frenum bare, rather narrow, its 

 length hardly one fifth of the total length of the scutellum, marked off by a weak line, with 

 traces of longitudinal costulae. Dorsellum small, alutaceous. Propodeum medially nearly 

 one third as long as the scutellum, with a row of irregular punctures along its base and along its 

 hind margin, the rest of its surface, between the spiracles, very shiny and almost smooth, some 

 traces of very weak oblique striae ; median keel a raised crest which in profile appears dentate 

 in its middle, channelled longitudinally, this channel interrupted at the point where the tooth is 

 situated ; callus clothed all over with long whitish hairs which spring from warts which give the 

 surface a rough appearance ; spiracles small, nearly circular, separated by only about one third 

 of their diameter from the hind margin of the metanotum. Postspiracular sclerite shiny, with 

 some weak irregular wrinkles. Femoral groove of mesopleuron more or less reticulate ; mese- 

 pisternum polished and smooth, extending down nearly to the mid coxa ; mesepimeron nearly 

 smooth, separated from the mesepisternum by an incomplete groove ; metapleuron shiny, 

 finely obliquely reticulate. Mesosternum finely reticulate and hairy, except for a shiny and 

 nearly smooth oval patch on each side of the middle ; mesolcus a shallow but distinct groove. 

 Fore wing (Text-fig. 198) hardly more than twice as long as broad, surpassing the tip of the 

 gaster ; costal cell about eight times as long as broad, its lower surface hairy throughout, its 

 upper surface hairy over the distal half but with a bare strip just above the submarginal vein 

 in the proximal half, the hairs long ; the rest of the wing is hairy except for a narrow strip below 

 the submarginal vein and another along the hind margin of the wing in its basal third ; fringe 

 of wing very short ; marginal vein about 2-4 times as long as the stigmal vein ; postmarginal 

 slightly longer than the marginal ; stigmal vein strongly curved, the stigma nearly parallel to 

 the costal edge of the wing, oblong and with a long uncus. Hind wing rounded at apex ; costal 

 cell with a row of hairs which extends throughout its length ; rest of wing hairy. Hind coxae 

 rather dull like the propodeal callus, finely reticulate except dorsally where it is somewhat rough- 

 ened, the rough sculpture forming a weak crest ; a band of hairs extends right along the dorsal 

 surface of the coxa, another runs along its ventro-lateral surface. The legs from the trochanters 

 onwards are thickly hairy. The spur of the mid tibia is nearly two thirds the length of the first 

 tarsal segment. 



Petiole of gaster very strongly transverse. Gaster (cf. Text-fig. 201) about 2-5 times as long 

 as broad in dorsal view, oblong-elliptic, slightly longer and much narrower than the thorax, 

 pointed apically, sunken dorsally, strongly compressed so as to be higher than broad, ventrally 

 strongly carinate over three quarters of its length ; the tip of the hypopygium is situated very 

 far from the base of the gaster and is provided with a long pale mucro (Text-fig. 201, m). The 

 sides of the gaster have a row of hairs on each segment (the apical segments have two or more 

 rows). The hind margin of the first tergite is entire. Tips of ovipositor sheaths projecting 

 very slightly. 



6" [undescribed] . Differs from 9 as follows: 



Antennae and coxae black ; mid tibiae fuscescent, hind tibiae fuscous except their bases and 

 apices narrowly ; tarsi infuscate, except the bases of the mid and hind ones ; fore wing in- 

 fumate, with a strong brown cloud which extends from the marginal vein about two thirds across 

 the wing ; basal and costal cells somewhat brownish, the basal vein marked by a brown curved 

 line ; hind wings infumate, more distinctly brownish beneath the marginal vein ; venation of 

 both wings fuscous. 



Antennae (Text-fig. 199) with scape more flattened and expanded, hardly 2-5 times as long
