ELLAMPUS. 419 



b. Fore wing with medial and 1st discoidal 

 cells complete, outer nervures of latter 

 outlined only in light brown but dis- 

 tinct ; apical margin of abdomen 



rounded, entire HOLOPYGA, p. 421. 



B. Claws of tarsi unidentate. 



a. Apical margin of abdomen rounded, 



entire ; teeth on claws of the tarsi 

 placed at a right angle to the inner 

 margin of claw HEDYCHRIDIUM, p. 424. 



b. Apical margin of abdomen laterally 



angular or subdentate ; teeth on claws 

 of tarsi not at right angles, apex 

 merely bifid HEDYCHRUM, p. 427. 



It is possible that two other genera of the Ellampina may 

 occur in India. These are characterized as follows: 



HOLOPHRYS, Mocsary. " Sides of the pronottun narrowly 

 applied againsb the anterior margins of the mesopleurse, its sides 

 as long as these margins ; no posterior lateral angles to the meta- 

 pleurae ; apical margin of 3rd abdominal segment entire " (du Buys- 

 son). Founded on a species from Sumatra. A second species has 

 been described by du Buysson from the regions of the Congo in 

 West Africa. 



PHILOCTETES, du Buysson. " Posterior tibiae (especially in the 

 c? ) dilated. In the d 1 these are also slightly hollowed. Third 

 abdominal segment very lightly sinuate at apex." (du Buysson.) 



Genus ELLAMPUS. 



Elampus, Spin. Ins. Liy. i (1800), p. 10. 



Notozus, Forst. Vcrh. nat. Ver.preuss. Rheinl. x (1853), p. 331. 



Omalus et Elampus, Dahlb. Hym. Eur. ii (1854), pp. 26 & 38. 



Type, E. auratus, Linn., from Europe. 



Range. Both hemispheres. 



$ <3 . Head transverse, as broad as the pronotum or broader ; 

 facial cavity subtriangular, the arch above narrowing distinctly, 

 moderately deep ; antennas slender, cylindrical. Thorax broad, 

 very convex above : the pronotum long or short, often shorter 

 than the mesonotum, transverse ; metanotum and scutellum 

 convex, the former sometimes gibbous anteriorly; mesopleurae 

 convex or flat, the apex beneath more or less rounded : post- 

 scutellum convex, gibbous or with a inucro at base : posterior 

 lateral angles of median segment produced, apex acute or obtuse. 

 Wings: fore wing with medial cell only complete, the 1st sub- 

 medial and sometimes the radial cell almost complete, generally 

 two-thirds of the apical portion of the radial nervure is obliterated, 

 occasionally the 2nd submedial cell is faintly outlined ; nervures 

 and cells of the hind wing obsolete ; legs slender, the posterior 

 tibise not incrassate ; the claws of the tarsi multidentate. Abdo- 

 men very convex above, the base transverse, the apical margin 

 rounded at the sides, truncate and incised in the middle. 



Onlv two species have sc far been recorded from India.
