I described this species under CepJialocera, as Bigot's MS. name 

 for it was adopted, but, as the proboscis is short and labella are 

 present, it must be referred to Mi/das. 



Genus LEPTOMYDAS, Gerst. 

 Leptomydas, Gerstaecker, Stett. Ent. Zeit. xxix, p. 81 (1868). 



GENOTYPE uncertain ; * Mydas lusitanicus, Wied., according to 

 Coquillett (1910). 



This genus differs from Mydaa in the long proboscis, in the 

 absence of a spur to the hind tibiae, and the presence of a wreath 

 of spines at the tip of the abdomen in the $ . From Ceplialocera 

 it differs by the presence of the labella. 



Range. South Europe, Egypt, Arabia, Sudan, India, East and 

 South Africa, North and Central America. % 



253. Leptomydas indianus, Bnm. (PI. IV, fig. 1.) 



Leptomidas indianus, Brunetti, Eec. Ind. Mus. vii, p. 478, fig. 12 

 (1912). 



$ . Head much wider than thorax ; frons black, shining, with 

 two narrow diagonal grooves on upper part ; vertex consisting of 

 two dark brown shining oval calli placed end to end, with a small 

 recessed space between them ; face rather dark grey, smooth ; 

 antennae missing, except the short, .cylindrical, dark brown, 

 slightly pubescent first joint, placed on a slight transverse ridge 

 running from eye to eye ; eyes prominent, black, bare, shining ; 

 proboscis and oral opening dark brown, shining, former very 

 short ; back of head grey ; the whole frons, face, back, and under- 

 side of head with moderately thick (but not dense) grey hairs. 

 Thorax dull black, with a little dirty grey tomentum towards the 

 sides and posterior part, and on the humeral calli, which bear a 

 small bunch of coucolorous hairs ; similar hairs on posterior part 

 of dorsum, in front of and below the wings ; sides of thorax more 

 or less shining black, mostly bare; prothorax and neck with 

 silvery-grey tomentum ; scutellum and metanotum blackish, 

 with silvery-grey tomentum. Abdomen cylindrical, slightly nar- 

 rowed in middle, very dark blackish brown, shining; posterior 

 borders of segments pale yellow, most distinct on 2nd to 5th seg- 

 ments ; the bands on the 2nd, 3rd, and 4th segments passing 

 unbroken over the sides and across the venter; 4th segment light 

 reddish brown ; whole abdomen minutely pubescent ; 1st and 2nd 



* There is a little uncertainty here, as in the Kertesz Katalog lusitanicus is 

 referred to Mydas again, although Leptomydas is acknowledged as a valid 

 genus. The next species guen by Gerstaecker is cincfus, Macq., which Kertesz 

 puts in Syllcyomt/das. Gerstaecker's third species is rujipcs, Wied., which 

 Kertesz retains in Leptomydas. Therefore, if lusitanicus is really a Mydas, the 

 type of Leptotomydas may be rufipcs, Wied.
