GYMNASTES, Brun. 



Alexander regards this genus as synonymous with TeHcholahis, 

 Os. Sac. One of the principal characters of my genus was the absence 

 of a distinct neck, which in Teucholabis is obviously elongate as stated by 

 its founder. 



This is the case in the three oriental species of Teucholabis before me : 

 fenestrata, Os. Sac, insignis and biannulata, mihi. Also, none of these 

 species have any incrassation of the hind femora. The close approxima- 

 tion of the auxiliary vein to the 1st longitudinal seems a good character 

 in Gymnastes. Alexander says some species of Teucholabis approach 

 my genus in venation. However, Mr. Edwards has pointed out ^ a cha- 

 racter which had escaped me and on which he thinks the genus can stand 

 at least provisionally, i.e., the presence of small scales covering the legs. 

 My G. violaceus is synonymous with his Teucholabis cyanea, a species 

 which may now be referred to Gymnastes, to which genus he also adds a 

 new species and refers Gnophomyia ornatipennis, de Meij.- The species 

 belonging to the genus now are as follows :

(^. S. W. India. Long. 3| — 1 mm. 



Head brownish-yellow, frons with a median blackish stripe and often 

 a transverse one also ; palpi and antennae black, scape brownish-yellow. 



Thorax. — Dorsum shining black ; shoulders broadly brownish-yellow, 

 the colour extending more or less anteriorly and as far hindward as the 

 transverse suture. Sides of thorax dull brownish-yellow with darker 

 paits ; scutellum and metanotum black. 



Abdomen dull black with short dark pubescence ; genitalia con- 

 colorous. The latter consist of a pair of conical dark brown, long-haired 

 claspers somewhat attenuated towards tips, a large oblong slightly 

 curved brownish-yellow ventral plate from the centre of the hinder 

 margin of which projects a concolorous cylindrical style as long as the 

 claspers. 



Legs. — Ground colour brownish-yellow with very short black pubes- 

 cence, but almost entirely covered with small black scales so that they
