4. NEMOTELUS 125 



AT hrevirostris being referred to tlie female of this species, as his character of 

 "Abdomen with three rows of tawny spots which are connected along each side 

 istpplicable to no other species and certainly does not apply to the species now 

 recognised as N. hrevirostris Meig. 



4. N. nigrinus Fallen. Black. Frons without any white spots. Cubital 

 vein not forked. 



A small species, well distinguished by its entirely black 

 abdomen in both sexes and by the absence of any fork to the 

 cubital vein. 



A Face frons, and vertex all shining bkiish Ijlack and quite bare ; face moder- 

 ■ ately produced for a Nemotelm (fig. 123), conical but not sharply pointed ; 

 iowls and back of the head also black and with a slight pale pubescence on 

 the slightly inflated lower part of the latter ; ocelli conspicuously yellow. 

 Eyes apparently touching for about one-third the distance between the 

 occiput and the antennae; facets on nearly the upper two-thirds larger, 

 lighter brown and sharply contrasted against the smaller darker facets on the

lower part • in life the eyes are probably banded as in the female. Antennae 

 brownish black, with the tip of the second joint often more yellowish brown, 

 moderately short, and placed high up, as the frons itself is not m the slightest 

 deo-ree produced and consequently the antennae appear (m profile) to be 

 placed at the extreme upper base of the snout-like face ; basal joints short 

 and almost bare ; third joint annulated, longer than the two basal joints 

 too-ether and with a terminal arista which is only about as long as the last 

 annulati'on of the third joint, while the tip third of the arista consists of only 



a very fine hair. ,..,,, ^ . ^ i ^ ^u 



Thorax and scutellum shining black and punctate, but there are two 

 rather dull impunctate stripes between the middle and the sides ; there is a 

 yellow spot on the humeri which is continued as a narrow line to the Aving- 

 base and then descends (more or less indistinctly brownish yellow) between 

 the mesopleurse and the pteropleurae. Pubescence entirely absent on the 

 disc but there are some very short and inconspicuous pale hairs aljout the 

 side's and on parts of the pleurae. Scutellum and metanotum roughened or 

 even almost shagreened. 



Abdomen shining black, sparsely punctate, and apparently bare as the 

 brownish yellow pubescence about the basal corners is very minute. Belly 

 shininf black, but just the hindmargins of the third and fourth segments 

 obscurely brownish yellow. Genitalia with two pairs of tiny brownish yellow 

 lamellse, and between them a pair of darker brown style-like processes. 



Leo-s black, but orange on the tip of all the femora, on almost all the 

 anterior tibia}'(as only the lower half or so of the upper side is a little 

 darkened), on the base and the extreme tip of the hmd tibiae, and on the basal 

 two or three joints of all the tarsi. Pubescence practically absent, but a 

 little can be traced behind the middle femora. _ ^ • , i
