Prosopis elongata Smith. 



Dandenong Ranges, Victoria (RoUe). 

 Prosopis rufipes Smith. 



Australia (Schiilf:;) . The specimen is a male, this sex being un- 

 described. It runs to the same place in the table of Australian 

 Prosopis as the female, but has the labrum, mandibles, clypeus, a low 

 broad supraclypeal mark, the lateral face-marks, a stripe on scape, 

 upper edge of prothorax narrowly, and tubercles, all cream-color. 

 The second abdominal segment has a large black patch on each side. 

 The lateral face-marks are peculiar, extending very narrowly a 

 long distance up the orbital margin, and having a thorn-like projec- 

 tion opposite the antennae. The antennae are not especially long; the 

 flagellum is ferruginous beneath. 



Prosopis chrysaspis, new species. 



Female. — Length 10.5 mm.; black, with the following parts bright chrome 

 yellow, semilunar lateral face-marks, projecting upper border of prothorax, 

 tubercles, scutellum (except anterior edge, failing in middle, which is black), 

 but not postscutellum ; flagellum ferruginous beneath ; legs obscurely reddish, 

 anterior tibiae and tarsi ferruginous on inner side ; wings perfectly hyaline, 

 nervures and stigma ferruginous; first r. n. joining first t. c. ; second s. m. 

 long ; head broad ; clypeus strongly and quite densely punctured ; mesothorax 

 dullish, with scattered punctures of different sizes ; first ventral segment of 

 abdomen obtusely keeled ; anterior femora swollen. The lateral face-marks 

 end obtusely above, not on orbital margin, and extend a little above level of 

 antennae. In my table of Australian Prosopis this runs, except for its large 

 size, to the insect labelled cyanura in the British Museum, but which has the 

 abdomen black, whereas cyanura Kirby is described as having it " atro- 

 caerulescens." 



In appearance the new species resembles P. morosa Smith, but 

 it is less robust, and differs in the markings of the thorax and face, 

 those of the face especially being wholly different. 



Habitat. — Adelaide, Australia {Schomburgk). Berlin Museum, 

 19384. 



Prosopis chrysognatha, new species. 



Male. — Length about 7.5 mm. ; black, with the markings bright chrome- 

 yellow, as follows, transverse spot on labrum, narrow stripe on upper side 

 of each mandible, entire face up to level of antennas (deeply notched by 

 antennal sockets), tubercles (but no other part of prothorax), scutellum 

 (except anterior and lateral margins), postscutellum, anterior femora beneath 

 (except at base), anterior tibiae (except a brown band on inner side), middle
