7. SARGUS 173 



dull blackish ; basal joint with rather dense_ black pubescence ; second joint 

 about as long as the first but broader, and with the pubescence on the upper 

 side less dense but longer; third joint slightly longer than either of the 

 others and with four indistinct annulations, of which the last one is the 

 smallest in bulk and bears at its extreme dorsal base the long arista, which is 

 therefore by no means apical ; arista about as long as the antennae, and with 

 two or three short plumes near its base. 



Thorax and scutellum brilliant green, sometimes with purplish reflections 

 on the back part and on the scutellum, and all finely punctate ; pubescence 

 composed of two sets of hairs, as there is a rather dense short brownish 

 orange pubescence which becomes black or almost black on at least the 

 hinder half of the disc, and intermingled with it there is (except on the 

 front part) a sparse long blackish or brownish pubescence which is about 

 three times as long as the short dense pubescence; the short pubescence 

 forms a slight crest at quite the front part, except that the absolute front 

 part of the disc is polished and bare so as to allow free action for the head ; 

 when viewed from in front all the pubescence on the sides of the disc is 

 long and broadly and conspicuously brownish orange ; pleurae bluish black, 

 with obvious long dull yellow pubescence near the humeri (twelve to twenty 

 hairs), on the back part of the mesopleuras, on the sternopleurae, and on the 

 metapleurse, but polished and bare on most of the mesopleurse right ixp to the 

 dorso-pleural suture, and with a depressed space there for the reception of the 

 front femora. Scutellum with shorter and mainly black pubescence ; meta- 

 notum large and bright green, with upturned rather long pale pubescence on 

 the lower part. 



Abdomen brilliant green, but slightly more blackish than the thorax 

 because of its denser coarser punctuation ; it is club-shaped as it gradually 

 increases in width from the base to near the end of the fifth segment, but the 

 sixth segment is very much narrower and is bright coppery aeneous. Pubescence 

 on about the lateral quarters of the three basal segments long, thin, erect, 

 and orange-yellow, but not appearing dense unless viewed from behind, 

 while on the sides of the fourth and fifth segments it is shorter, more sloping, 

 and mostly black unless almost over the sides, and it is black all round the 

 hindmargin of the fifth segment and all over the sixth segment : all over the 

 disc there is a very short, but dense and coarse, suberect black almost bristly 

 pubescence which is sometimes slightly encroached upon by the brownish 

 orange pubescence at the hind corners of the segments. Belly brightly 

 shining aeneous, very finely punctate, and bearing universal recumbent yellow 

 pubescence. Genitalia small, dull blackish, curved under the sixth abdominal 

 segment, and ending in a pair of hairy lamellae which are shorter than those 

 of S. iridatus. 



Legs mainly black ; coxae shining black with light grey pubescence ; tro- 

 chanters shining black but orange at the base and tip ; femora conspicuously 

 orange at the tip ; anterior tibiae broadly but indefinitely orange at the base 

 (about one-third) and narrowly at the tip, while the hind tibiae have about the 

 basal half more or less reddish orange and even all the rest tinged with reddish 

 orange ; hind femora with the orange tip extended beneath ; anterior tarsi 

 brownish on the basal joints, and the middle pair often yellowish brown for 

 more than the basal joint; hind tarsi bright reddish orange for at least the 

 basal half of the basal joint on its; upper side and on all its under side ; 

 anterior tibiae a little dilated on the apical half, and the hind tibiae with a 

 slight kink just after the middle, before which they are slightly dilated ; 

 basal joint of the tarsi much shorter than in S. hipunctatus but longer than in 

 S. cuprarius. Pubescence very slight and inconspicuous, moderately long, 

 but thin behind the anterior femora, and pale everywhere except on the 

 upper side of the darkened tarsal joints, where it is much more extensively 

 black than in S. rufij^es. 



Wings suffused with a slight blackish brown tinge, which becomes more 

 intense about the stigma and the space below so that sometimes there is a 

 rather blackened cloud on all the middle part of the wing ; veins blackish. 

 Alar squamae rather small, obscurely blackish brown with brownish yellpw 

 fringes ; thoracal squamae forming a short thick blackish brown club, which 

 bears long yellowish brown pubescence all over. Halteres bright orange.
