10. BERIS 209 



Loew tells strongly in its favour. It is possible that B. nigra Meig., also described 

 from a female sent from England by Dr Leach, may represent the female of 

 B.fuscipes, but I think the probable original type in the Paris Museum is only £. 

 chalyheata, though it is hardly in perfect enough condition to decide. 



5. B. chalybeata Forster. Abdomen all blackish. Legs dull orange to 

 pale brown, imicolorous except for the tarsi. Frons of the female fully 

 one-third the width of the head. Thorax of the male black haired. 



S . Head black ; f rons shining black, rather large and broad, with a broad 

 depressed channel down the middle of its upper part, and bearing fairly long 

 rather upturned black pubescence ; face broad (half the width of the head) 

 and arched, clothed with a rather long slightly upturned brownish black 

 pubescence, which becomes rather dark greyish on the jowls ; lower part 

 of the back of the head inflated and bearing dense blackish pubescence, but 

 the uj^per part shallow ; the back of the head when seen from above bears 

 dense black rather long pubescence (very different from B. Morrisii), which 

 does not reach beyond the level of the eyes when seen from in front ; vertex 

 considerably elevated and bearing moderate black pubescence ; proboscis 

 black at the base but with obscure orange moderately large sucker-flaps • 

 palpi not evident. Eyes touching for a fairly long space, densely clothea 

 with rather long brownish black pubescence ; facets on the upper half larger 

 than those on the lower half but with no abrupt division. Antennae dull 

 black, hardly as long as the head and jjlaced only a little more than half-way 

 down the head ; two basal joints almost equal in length and bearing minute 

 bristles ; flagellum hardly twice as long as the two basal joints together, grey 

 inside about the middle, and bearing minute hairs on the blunt tip ; the 

 flagellum is but little attenuated and ends bluntly. 



Thorax and scutellum shining blackish teneous, in fact almost black, 

 moderately but rather coarsely punctate on the front part but with the 

 punctuation growing finer and scarcer until the back part and scutellum are 

 almost impunctate, and bearing a double blackish pubescence of which the 

 short hairs are rather dense while the longer hairs are less abundant and not 

 extended to quite the front part ; pleurae with brownish or rusty black 

 pubescence except on the bare polished middle part of the mesopleurse. 

 Scutellum (fig. 145) usually with six shining dark green or almost black spines 

 of which the outer pair are small, but sometimes there are eight spines or 

 (according to Loew) sometimes only four ; the pubescence is similar to that 

 on the back part of the thorax and extends up the spines to their tips. 



Abdomen dull black with a slight purplish tinge ; pubescence blackish, 

 rather long down the sides and not scarce. Belly with minute depressed pale 

 grey pubescence, but with one or two black bristly hairs at the hind corners of 

 the last two segments. Genitalia large, protruded from the seventh segment, 

 with a large rounded end plate, above which are small brownish black 

 lamellae, while underneath they are usually conspicuously keeled. 



Legs ranging in colour from dull brownish yellow to brownish orange or 

 almost or quite darkish brown, but never anywhere at all approaching to 

 black except on the coxae and tarsi ; basal joint of the hind tarsi 

 obviously longer than the other four joints together, brownish yellow 

 and sometimes that joint of the middle tarsi slightly brownish ; basal 

 joint of the hind tarsi considerably incrassated and arched above so that 

 the crown of the arch (as seen in profile) is beyond the middle of the joint, 

 and the joint there is quite as high as the other tarsal joints. Pubescence 

 fairly long, blackish and obvious behind the front and hind femora ] on 

 the hind tibiae there is a pale ciliation inside (=behind) except at the base. 



Wings with a very strong blackish tinge, but with the costal and sub- 

 costal cells a little clearer and with the large stigma distinctly blackened. 

 Alar squamae small, blackish brown with brownish fringes ; thoracal squamae 

 absent. Halteres dark brown, knob elongate.

?. Rather similar to the male, but the wings are much lighter, though still 

 decidedly brownish, and the stigma is consequently much more conspicuous.
