Runs in my table of Prosopis to the vicinity of P. amicula, 

 from which it is easily known by the reduced face-markings. 

 It resembles in its markings P. flavojugata, CklL, but that 

 species has a much shorter head, the yellow spots on the 

 face lower down, and the quadrate second submarginal cell 

 entirely different from that of kelvini. In P. amicula also 

 this cell is very much shorter than in kelvini. The second 

 s.ra. of kelvitii is formed much as in P. alcyonea (Erichs.), 

 which is in other respects a totally different insect. 



Prosopis leai, sp. n. 



(J . — Length about 65 mm. 



Rather slender ; the abdomen subclavate, narrowed 

 basally; black, with yellosv markings; head moderately 

 elongate, face below antennse yellow (reddened by cyanide in 

 type), the very broad supraclypeal mark obtusely rounded or 

 subtruncate above, the lateral marks ending abruptly at 

 level of antennae, the lower margin of clypeus dark ; scape 

 with a yellowish mark in front ; flagellum long, ferruginous 

 beneath ; the large tubercles, scutellum, and postscutellum, 

 with a small elongate mark touching each anterior corner of 

 scutellum, very bright chrome-yellow ; no other yellow on 

 thorax ; mesothorax dull, the dense punctures so minute as 

 to give tlie effect of a minutely granular surface ; area of 

 metathorax shining, without distinct sculpture. Legs black ; 

 anterior tibiae ferruginous in front ; tegulae piceous. Wings 

 dusky at apex ; nervures and stigma dark ; first r. n. joining 

 first t.-c. ; second s.m. longer below than high, but not much 

 elongated. Abdomen dull, scarcely hairy ; venter normal.

Best compared with P. chrysognatJia, Ckll., and P. apo- 

 suara, Ckll., from both of which it differs by the much finer 

 sculpture of the mesothorax. The broad supraclypeal area 

 also separates it at once from P. aposuara. The second 

 submarginal cell is shorter than in chrysognatha.
