ACANTHOUil'IS. 317 



the large convex clypeus. Thorax as in A. fraueiifeldi, but not 

 so strongly constricted at the mesonotutn, with the large lateral 

 obtuse tubercles or teeth on the metanotum proportionately larger, 

 the metanotum itself finely sculptured. Node of the pedicel 

 with the upper border strongly emarginate and bidentate; abdomen 

 oval, broad, anteriorly rapidly narrowing towards the apex. 



5 . Brown, with a more or less dense golden-yellow pubescence. 

 Except that it is slightly larger and the node of the pedicel above 

 is more deeply emarginate, it is scarcely distinguishable from 

 A. frauenfeldi $ . 



'<? Brown, smooth and shining, apparently without pilosity or 

 pubescence; mouth-parts, antenna and legs pale whity-brown. 

 For the rest the characters of the genus. 



Length, g 2-3-3-3 ; $ 5-3 ; tf 2 mm. 



Hab. The Himalayas to 5000 ft. (Smythies <f- Matter) Central 

 India (Sckurr) ; Poona ( Wrouyhton) ; Ceylon (Simon). Extending 

 to Aden and North-eastern Africa.

 p. 412, . 



" $ . Resembles A. capensis, but is more slenderly built ; meso- 

 notum more constricted. Head narrow, oval, much longer than 

 broad. Eyes placed laterally in the middle. Metanotum with two 

 strong obtuse teeth. Node of the pedicel thick, bispinous, with 

 tingles laterally below the spines. Pilosity of the body longer, 

 more abundant, very fine and very acute. Thorax and node of 

 the pedicel of a reddish yellow, with brown markings on the back. 

 It is perhaps a race of A. capensis. 



" Lengtfi, 2'3 mm. 



" Hab. Mussoorie." (Forel.) 



Unknown to me, but apparently very well distinguished by the 

 elongate head. In all the other Indian species the head without 

 t he mandibles is nearly as broad as long.

 p. 43, ; Jour. Bomb. N. H. Soc. viii (1892), p. 412, . 



$ . Closely allied to and resembling A. capeiusis, Mayr, but 

 smaller and entirely without pilosity or pubescence. Black, the 

 mandibles, antenna;, and the tibiai and tarsi of the legs brownish 

 white. Head short, shorter proportionately than in A. capetusis 

 and not so rounded above, transverse ; mandibles proportionately 

 large, acutely dentate ; clypeus very convex ; antennae short, the 

 scape extending only a little beyond the top of the head. Thorax 

 narrower and more constricted than in A. cajwisis, the metanotum 

 enlarged posteriorly, with proportionately much smaller lateral 

 obtuse teeth or tubercles. Node of the pedicel only slightly 

 emarginate above, the lateral angles of the margin above not spinous 

 or dentate : abdomen as in A. cajtenmt.
