are finely pubescent, with the apex (neck) glabrous, the 6 joints of 

 the flagellum have verfcicillate caducous setae, not longer than the 

 thickness of a joint, the ultimate joint bears a similar seta at apex. 

 Thorax hood-like, mesonotuni with a greyish, pruinose stain on each 

 side in front. Scutellum with long, vertical, and moderately dense 

 setae. Wings glabrous, longer than the body, brownish black, 

 neuration of Chironomus, cubitus reaching almost the alary point, 

 the costal not projecting beyond it, the double nervule of the radius 

 transverse, oblique, the discoidal prolonging the direction of its basal 

 part and ending at the alar point, the bifurcation of the postical 

 hardly proximal to the transversal, the 2 rami as in Chironoinua ; the 

 auxiliary produced beyond the transversal, the second longitudinal 

 indistinct. Legs long, hardly thick, the setae very short, much 

 shorter than the thickness of the legs ; femora widened, thong-like, 

 anterior tibia longer by one-half than the metatarsus, all the tibiae 

 without a pecten and crenulate ring; fore metatarsus twice as long 

 as the 2nd joint ; joints 2-4 slightly and gradually shortened, all of 

 them weakly dilated at the distal end, the 4th cordiform, hardly 

 twice as long as thick, 5th longer than the 4th on every leg, trilobate 

 at apex ; median lobe longest, rounded at tip, the other 2 lobes 

 lateral, empodium long, almost as long as the hooks, ramose, the 

 rami several times divided, all tarsal hooks slender and simple in the 

 female, thick, black, and bilobate in the male, the outer lobe obtuse 

 and very finely denticulate at apex, the inner lobe ending in a point. 

 Abdomen weakly depressed in the male, basal joints of forceps long 

 and thick, the terminal short, pubescent, club-like. Abdomen of 

 the female more strongly depressed, the first 7 segments very trans- 

 verse, 8th compressed, gradually attenuate into a point half the 

 length of the 7th at its anterior part, but longer than the 7th, and 

 ending in 2 long, straight juxtaposed laminae. 



Length : 5 mm. Cape Town. Flits on the sea-shore in dark 

 nights. (L. Peringuey.) 



PARACLUNIO MINOR, n. sp. 



3 $ . Brown, antennae and legs brownish yellow. Antennae 

 shaped as in the preceding species, except that the 7th joint in both 

 sexes is not narrowed in a slight stiletto point at apex, but is conical 

 and concolorous ; the verticillate setae have doubtless dropped, 

 because I detected one only on the 2nd and another on the 7th. 

 Wings less fuscous than in the preceding species. Fore tibia almost 

 twice as long as the metatarsus, the latter a little longer than the 4 

 preceding taken together, 2nd equal to the 3rd and 4th also taken
