486 Mr. T. D. A. Cockerell — Descriptions and 



remarks that some of the species cannot be distinguished 

 from P. varifrons. The male which Metz refers to P. sub- 

 t/istis, of which I have an example determined by Metz 

 (Oimsby County, Nevada, July, Baker), is quite distinct, 

 and is really related to P. episcopalis, having the yellow 

 markings reduced and the lateral face-marks much narrower 

 above. It is P. universitatis, Okll., which Metz remarks " is 

 probably the variety subtristis" 



Prosopis luzonica, Cockerell. 



<$ . — Length about 7 mm. 



Black, with broad transverse mark on lower margin of 

 clypeus, lateral face-marks (rather narrow, notched at an- 

 tennal sockets, and ending narrowly on orbital margin below 

 level of middle of front), interrupted line on prothorax, spots 

 on tubercles and tegulse, anterior tibiae in front, middle tibiae 

 at extreme base, rather more than basal third of hind tibia?, 

 and all the basitarsi yellow ; flagellum long, the apical part 

 ferruginous beneath. 



Hab. Mt. Banahao, Philippine Is. (Baker coll. 3664). 



The species was described from a female. 



Prosopis mindanensis, sp. u. 



<$ . — Length about 6*5 mm. 



Black, with a large triangular mark on lower part of 

 clypeus, lateral face-marks (shaped like feet on tip-toe, broadly 

 truncate at about level of middle of supraclypeal area, but 

 continued narrowly a short distance up orbital margin), small 

 stripe on scape, interrupted line on prothorax, tubercles, spot 

 on tegula?, anterior tibiae in front, and bases of middle and 

 hind tibiae yellow ; anterior tarsi ferruginous, the small joints 

 dusky, the other tarsi black ; face rather long and narrow; 

 antenna} short for a male, reaching about to level of tubercles, 

 third and fourth joints very short, flagellum obscure reddish 

 beneath; mesothorax rather strongly and extremely densely 

 punctured ; area of metathorax coarsely wrinkled. Wings 

 greyish hyaline ; first r.n. meeting first t.-c. ; second s.m. 

 longer than high ; first abdominal segment shining, with 

 extremely fine punctures; the other segments also very 

 finely punctured, without any distinct hair-bands or patches; 

 stipites long and spine-like. 



Hab. Dapitan, Mindanao (Baker coll. 3663). 



Kesembles P. palavamca, Ckll., but is distinguished by 

 the shorter antenna?, yellow bases of middle and hind tibiae, 

 broader abdomen, &c. Among the continental Asiatic species 

 it is related to P. feat, Vachal.
