Prosopis digitata feilorica^ suhsp. n. 



cJ. — Lcngtii about 4 mii). 



Runs ill my table of Prosopis (' Eiitomolo^^ist,' 1898, 

 p. 186) to /*. subdit/itata, but diflFers as follows : — Supra- 

 clypeal mark lar<;e and broad, truncate and not at all elon- 

 gated above ; lateral marks with the uj)ward finger-process 

 very short, ending at same level as toj) of supraclypeal mark ; 

 fides of lateral marks forming an acute an^rle with orbit 

 above, the point where they huive the orbit being lower than 

 their upper edge niesad of the finger-like process ; scape with 

 a light yellow stripe; area of metathorax strongly rugose- 

 wrinkled in the basal middle, but otherwise; nearly smooth 

 though dull, the sides very wt 11 defined by a curved sulcu-*. 

 Fbigellum dull ferruginous beiu-ath ; thorax wholly without 

 light maikings; markings of face very j)ale yellort'. Wings 

 greyish, iridescent. Legs witli the yellow rather more 

 extended than in P. digitata. 



This is a southern member of the group of species or races 

 called P. digitata, suhdigitata, and rndbec/cue (see * Psyche,' 

 June 1896, p. :U).

At the same time and place Mr. Birkmann took a variety 

 of /*. georgica, CkU., smaller than the type, with the face- 

 markings pale instead of i)right yellow, and a black spot on 

 the hind tiliia2 within. Tiiis insect, which is easily known 

 from P. zizicv and its allies by the very narrow lower part of 

 face, may stand as P. georgica, var. leeana, nov. The scape 

 is broad, with the anterior half light yellow. It is inter- 

 esting to find at one spot in Texas two forms of Prosopis, one 

 a modified representative of a Rocky Mountain group, the 

 other a variety or 8ubsj)ecies of a type belonging to the 

 South-eastern States. At the same time and j)lace there al.-o 

 occurnd an example of /''. sayt, Rob., a species characteriistic 

 of the Northern States east of the plains.
