Hah. Shillong, Assam, May 1903 (R. Turner ; British 

 Museum). 



Smaller than S. famipennis, and with more of abdomen 

 red than S. montanus. It is also readily known by having 

 only two submarginal cells, a character which it shares with 

 the American S. [Dialonia] antennarice, Rob., and S. distolus, 

 Lovell. 



Exomalopsis periinelcena, sp. n. 



? . — Length about 8"5 mm. 



Robust, black, with black hair, except that on dorsum of 

 thorax, which is clear white ; mandibles bidentate, with a 

 tulvous sub ipical patch ; eyes converging below, but face 

 broad ; ocelli quite huge, in a curve ; antennae entirely dark, 

 ilagellum siiort ; discs of mesothorax and scutelkim bare, 

 polished and shining, with only very minute scattered punc- 

 tures ; legs with dense black hair, scopa of hind tibia and 

 basitarsus very large, dense and compact, but with many long 

 black hairs projecting beyond the general mass ; tegulse 

 black. Wings rather short, strongly smoky ; b. n. meeting 

 t.-ni.; marginal cell ending in a point (slightly appendicu- 

 iate) away from costa ; second s.m. subtiiangular, receiving 

 first r. n. at its apex ; third s.m. at least as large as first. 

 Abdomen broad and short, smooth and shining, with black 

 hair at apex. 



Hab. V. del Lago Blanco, Chubut, Patagonia (British 

 Museum). 



A very peculiar species, not a typical Exomalopsis. E. 

 herbsti, Friese, is black-liaired, with disc of thorax and head 

 above white-haired, but it has the scopa pale.
