422 R. OSTEN SACKEN 



leschall, but rejected by Schiner, may be revived yet. The face 

 of C. lupina shows the same bladderlike swelling as C. ferrugi- 

 nosa ; and the female of the latter also has spatulate palpi , 

 which is therefore a sexual caracter. 



Leptis uniguttata n. sp. </. Abdomen yellow , with black 

 crossbands, black at tip ; wings uniformly brown , with a hya- 

 line spot in the second basal cell. Long. corp. 7-8 mm. 



Antennae yellowish ; frontal triangle (above the antennae) 

 gray; vertical triangle gray in front, black behind (around the 

 ocelli). Thorax grayish-black above, humeral callosities and a 

 spot in front of the scutellum, pale yellowish ; pleurae grayish ; 

 scutellum black ; halteres with a black knob , stem brown. 

 Abdomen : first segment yellow ; segments 2-4 yellow, wdth a 

 broad black crossband , occupying nearly the whole segment , 

 except a very narrow anterior and a broader posterior margin, 

 which are yellow ; the crossband is deep velvet black anteriorly , 

 but less intensely black and more shining, posteriorly; it rea- 

 ches the lateral margins of the segments, but does not invade 

 the venter, which is yellow; segment five is nearly altogether 

 black , very little yellow being visible on the anterior and po- 

 sterior margins ; segments 5-6 are black on the dorsal, as well 

 as the ventral side; on segm. 5 a little yellow spot is visible 

 on the posterior margin. Legs yellowish-brown ; hind femora 

 and tibiae with a broad brown band in the middle ; tarsi 

 brownish toward the tip. Wings uniformly colored with brown, 

 except an oblique hyaline spot at the distal end of the second 

 basal cell. 



NB. I describe this species, although I have only a single 

 damaged specimen, because it is the only Leptis in the collec- 

 tion. The hind femora have, on the underside, near the insertion 

 of the tibiae, a small projection, clothed with short, stiff hairs, 

 which looks like a rudimental femoral spine. I do not find a 

 similar structure in the european species. 



Hah. Mt. Singalang, Sumatra, July 1878 (Beccari). A single 

 male.
