Prosopis vittatifrons n. sp. 



9 . Length about 4§ mm., rather slender; head and thorax 

 black, with the followmg parts cream-color: mandibles, labrum, 

 clypeus, a broadly triangular supraclypeal mark, lateral face-marks 

 (extending broadly up to beginning of facial fovese, then continued 

 for a short distance as a very fine line between fovea and eye), 

 a broad band on each cheek behind eye, and elongate mark on front; 

 tubercles, with extension to upper margin of prothorax, white; 

 tegulae pellucid; legs pale ferruginous, the hind ones a little stained 

 with dusky; abdomen with the first two segments clear ferruginous, 

 the others dark Ijrown, the hind margins of the third and fourth 

 more or less pallid, or the first two segments may each have a pair 

 of large brown blotches, with the third ferruginous, crossed and 

 largely covered by a large dark cloud; face broad; antennae light 

 ferruginous beneath; mesothorax dullish, microscopically tessellate 

 and punctured; wings hyaline, faintly dusky, stigma and nervures 

 dark brown; the two recurrent nervures meeting the transverso- 

 cubitals; second s.m. a little higher than broad. 



cf. Length a little over 3 mm.; face light yellow (primrose- 

 color) up to level of antennae, with an elongate frontal mark as in 

 female, the lateral marks shaped like a hand with the index-finger 

 pointed; first abdominal segment dark brown, pale ferruginous 

 apically, second the same, the broad red band notched on each side 

 in front, the second segment also red basally; remaining segments 

 dark. 



Habitat.— Furnong, S. Austraha, 29, 2cf (S. W. Fulton; Nat. 

 Mus. Vict. 221, 213, 145). The type is a female.- Runs in my table 

 to P. constrida Ckll., but is easily known by the elongate frontal 

 mark in both sexes; the male constrida has the clypeus, etc., white 

 instead of yellow.

 pinkish-white; labrum, mandibles, clypeus (except a rather broad 

 dark band down each side, not reaching lower margin), broadly 

 triangular supraclypeal mark, lateral marks (continued as a band 

 above to beginning of facial fovese), small mark on lower part of 

 cheeks, tubercles and an interrupted line on upper margin of pro- 

 thorax ; no frontal mark, no light mark on scutellum ; antennae pale
