another example of the same sex at Foxhall in Suffolk ; Piffard has also 

 taken it at Felden in Hertfordshire ; and Thornley at Leverton in Notting- 

 hamshire, on loth April. 



28. melanogaster, Thorns, 



Hemiteles melanogaster. Thorns. O. E. x. 9S2 ; Schm. Term. Fiiz. 1897, p. 523, $ ? . 



Black, with legs except base of coxae red, metathorax punctulate, 

 metapleurae scabrous ; $ with the legs black with the apices of the tro- 

 chanters, the anterior knees and tibiae testaceous, the hind tibiae being 

 nigrescent at base and apex. Length, 3-4 mm. 



Closely allied to H. Jlon'co/afor, Grav., in its hyaline wings, absent 

 epomiae, the lateral metathoracic costae wanting or lying close to the 

 pleural, with which the spiracles are nearly contiguous, the very finely 

 punctate central segments which bear sub-callose and nitidulous apical 

 margins and in the short radial appendix, but differing therefrom in the 

 metathoracic sculpture, black and dully sub-rugose abdomen and bicarinate 

 post-petiole. 



Bridgman devotes two lines in the middle of a paragraph (Trans. Norf. 

 Soc. 1890, p. 64) to the record of both sexes of this new British species ; 

 really, if insects new to the British fauna be recorded, it is only fair to the 

 systematist that they should be brought prominently forward in other than 

 a local society's journal. They were captured at Earlham near Norwich, 

 in July, 18S9. An allied species, H. sisyphii. Verb., has been bred from 

 the egg-sacs of Theridium sisyphmm, Clerck, in Germany.

Black. Head with palpi and mandibles ferrugineous ; clypeus discreted 

 and apically rounded. Antennae setiform, about length of body, with 

 scape usually rufescent beneath. Metathorax transversely rugose ; areola 

 broader than long ; apophyses sometimes acute. Abdomen oblong-ovate, 

 as broad as thorax, with central segments parallel-sided and sub-deplanate ; 

 basal segment sub-linear with post-petiole slightly longer than broad and a 

 little broader and shorter than petiole ; second and third segments some- 

 times with incisures castaneous ; $ valvulae distinct. Legs somewhat 

 slender ; the anterior red or stramineous with the coxae usually red with 

 black base, and the hind ones red or testaceous with the coxae, whole or 

 base of trochanters, centre or apices of femora, apices of tibiae and the 

 tarsi, infuscate or black ; 9 with hind femora red. Wings sub-hyaline ; 

 stigma infuscate, radix and tegulae whitish ; areolct pentagonal, nearly 

 always with outer nervure obsolete. Length, 3-5 mm. 



Gravenhorst instances a <$ variety, which is more slender, with all the 

 femora entirely testaceous, but it doubtless has no connection here, since 

 Taschenberg says its areolet is externally entire. 



The present species resembles a Pli\}:;adeiion (setisii Info), but the basal 

 segment is narrower and the areolet generally incomplete.

 the last taken at Botusfleming in Cornwall, and he also records it from
