338 Mr. C. G. Lamb on Exotic Gliloropiclte. 



four tubercles of. considerable length, compared with any 

 true Meroscinis, though falling far short of those in Dactt/lo- 

 th//rea, and these tubercles bear long brilliant orange spines 

 like those of Thyridula. The most remarkable character is 

 possessed by the male, which has large and complex hypo- 

 pygial segments resembling closely those of many Dolichopid.s. 

 This hypopygium has side-flaps carrying end- valves, between 

 which lies a long penis, while the previous segment carries 

 complex chitinous processes. 



Although the author is one of those who objects to multi- 

 plying genera, there appears in this case to be no escape 

 from the process. 



In addition to the above remarks, the following can be 

 added : — Like Meroscinis in general form of head and thorax, 

 the latter punctate, as is the elongate scutellum ; legs very 

 long, the front coxa especially so ; the thorax with normal 

 bristles and well developed. 



Type, the following species. 



Lonclionotus formosus, sp. n. 



Head (top-front view, fig. 11) :— All black, the triangle 

 very shining, not quite extending across vertex, the tip 

 extending right up to the antennae ; head-bristles all long- 

 but slender, normal as for Meroscinis, but the hair-rows 

 bordering the triangle are especially long. Antennas quite 

 normal, all dull orange, the 2nd joint narrowly bordered with 

 black on its margin, 3rd with a dusky tip ; arista slender, 

 black, finely pubescent. Side-view : vibrissa present, palpi 

 st u'ish, black. 



Thorax (fig. 12) bluish black, fairly coarsely punctate, 

 covered with black-brown hairs; last d.-c. and pleural bristles 

 long but slender. Scutellum rounded in vertical section, 

 triangular in profile ; hairs and punctures as on dorsum, with 

 ' four long tubercles each carrying a long brilliant orange 

 bristle. 



Wings (fig. 14) yellow, with yellow veins. Halteres 



yellow. 



Legs quite long, the front coxa being especially so, varie- 

 gated~with shining black and orange ; all coxae black, tro- 

 chanters yellow, femora and tibia? shining black except at 

 knees and extreme tip of tibiae; front tarsi orange on 1st 

 joint, others black, mid and hind tarsi black on last joint, 

 others orange. 



Abdomen shining black, but darkish orange on the basal
