The head of the male varies in breadth ; there are specimens, 

 in which it is as broad as the thorax is long. In the female 

 the breadth of the head also varies, but not as much as in 

 the male. 



Cleilamia lilurata n. sp. c/" 9 • 



This species is exceedingly like C. amabilis in the coloration 

 of body and wings ; but the antennae are darker, the halteres 

 yellow (instead of black) ; the apex of the wings has no other 

 brown border but that, naturally formed by the brown color 

 of tlie costal vein ; the brown pattern on the proximal half of 

 the wing is different, the space between the costa and the fifth 

 vein not being entirely filled out with brown. The venation is 

 different ; the second vein does not form that bold curve up- 

 wards , to come in contact with the first before its tip , and 

 then gradually merge in the costa, but takes the ordinary course, 

 with gentle sinuosities , and ends in the costa a little beyond 

 the tip of the first vein. The structure of the costa in the male 

 is very peculiar : there is a distinct depression or sinus about 

 the middle of the anterior margin, in consequence of whicli the 

 costa comes almost in contact with the first vein^ the latter 

 being free at both ends only. The costa shows, at its proximal 

 end, a peculiar swelling about 2 mm. long. , with an abrupt , 

 rounded ending , and a cross-suture before the middle ; it is 

 clothed with a microscopic pubescence.
