PTEROMALIDAE OF N.W. EUROPE 553 



Habrocytus conformis sp. n. 



$. Head and thorax with a weak bluish, bronze, or olive tinge ; gaster bronze with the basal 

 tergite more or less brassy, green, or coppery. Antennae blackish with the scape sometimes 

 testaceous proximally. Coxae, and femora except their tips, concolorous with the thorax ; 

 trochanters mainly dark ; rest of legs testaceous with the mid and hind tibiae more or less 

 infuscate medially, tips of tarsi brown, the fore tarsi more extensively so. Wings subhyaline ; 

 venation testaceous with the parastigma and stigma slightly darker. Length 2-5 to 3-1 mm. 



Differs structurally from the female of tripolii as follows : 



Pronotal collar slightly shorter medially, at most slightly more than one sixth as long as the 

 mesoscutum. Propodeum slightly shorter, about two fifths as long as the scutellum, its median 

 area 1-85 to 2 times as broad as long, the panels less uniformly reticulate and with some longi- 

 tudinal or oblique carinulae in addition to those present at the base of the propodeum. Gaster 

 slightly longer than the thorax, 1 -5 to 1 -85 times as long as broad, more acute, and slightly 

 acuminate, apically ; last tergite as long as or slightly longer than its basal breadth. 



o*. Unknown. 



Holotype $. England : Buckinghamshire, Hell Coppice, near Oakley, 25.vii.1957, 

 swept from grassy vegetation {Graham), in Hope Department, University Museum, 

 Oxford. 



Paratype. England : Oxfordshire, Otmoor, 1 $, 29.viii.1956, on a flower-head 

 of Angelica sylvestris L. (Graham), in Graham collection. 



Biology. Unknown. 



Habrocytus parietinae sp. n. 



(Text-figs. 376, 401, 407) 



$. Colour much as in tripolii sp. n., but antennae and legs paler. Antennal scape often 

 more extensively, sometimes entirely, testaceous ; flagellum testaceous at least beneath, 

 sometimes testaceous with only a little infuscation dorsally ; pedicellus often pale beneath and 

 apically. Tibiae usually entirely bright testaceous, occasionally the hind ones slightly infuscate 

 medially. Tegulae testaceous to fuscous. Body green to blue, without brassy or coppery tints. 

 Length 2-6 to 3-1 mm. 



Structurally, differs from tripolii as follows : 



Head in dorsal view (Text-fig. 407) 2-05 to 2-1 times as broad as long ; temples longer, only 

 slightly less than half as long as the eyes. Antennal scape (Text-fig. 401) more than three 

 quarters as long as an eye, reaching the level of the top of the median ocellus or even the vertex ; 

 combined length of pedicellus and flagellum hardly less than the breadth of the head ; pedi- 

 cellus about i-6 times as long as broad, slightly to distinctly shorter than the first funicular 

 segment ; funicle slender, proximally only slightly stouter than the pedicellus, weakly clavate ; 

 first funicular segment i-8 to 2 times as long as broad, the following segments relatively shorter 

 though all longer than broad, except the sixth which is quadrate ; clava about twice as long as 

 broad, slightly longer than the combined length of the two preceding funicular segments. 



Propodeum (Text-fig. 376) medially almost or quite half as long as the scutellum ; median 

 area 1-55 to 1-75 times as broad as long, its panels more irregularly sculptured with some coarse 

 wrinkles, some of them longitudinal, mixed with the reticulation ; costula rather more distinct ; 

 median carina distinct and sharp as far as the costula. Fore wing with lower surface of costal 

 cell with a complete row of hairs, also a few other hairs scattered over the distal quarter of the 

 cell ; speculum extending below the marginal vein for at most half the length of the latter ; 

 wing beyond the speculum more thickly pilose, the area between the postmarginal and stigmal 

 veins almost wholly pilose ; marginal vein 1 -4 to 1 -6 times as long as the stigmal vein ; post- 

 marginal vein from slightly shorter, to somewhat longer, than the marginal.
