Feb., 5 IO] ENTOMOLOGICAL NEWS. 67 



vertebrate Palaeontology of the University of California, I 

 am indebted to the courtesy of Prof. J. C. Merriam. 



At this time I take the opportunity to correct the following Errata 

 observed in the Monograph of the Eleodiini, namely : 



On page 18 the I2th line from the top should continue to read as 

 follows : "At this point the pleural region is differentiated, less so 

 in the fifth and not at all in the other segments." 



Omit line 13 from the top, same page. 



On page 19, in line 18 from the bottom, "inferior" should read 

 "ventral," and "postero-inferior" likewise "postero-ventral." 



On page 86, in line 19 from the bottom insert before "abdomen," 

 "first segment of ." 



On page 186, in line 9 from the bottom, read "tarsal grooves" in- 

 stead of "tibial grooves." 



New Bees of the Genus Prosopis. 



BY MYRON H. SVVENK AND T. D. A. COCKERELL. 



Prosopis grossicornls n sp. 



$ . Length 4.5 mm. Supraclypeal mark very large, its breadth at 

 base greater than that of lateral face marks at same level, continuing 

 but slightly narrowed upward for a distance equal to its breadth when 

 its margins abruptly and rapidly converge and terminate in a narrowly 

 truncate apex. Lateral face marks filling the space between the clypeus 

 and subquadrate portion of supraclypeal mark and the orbits, the up- 

 ward extension very short, less than width of the lateral marks and 

 barely attaining level of antennal socket, narrowly linear, curved, acu- 

 minate at tip and divergent from the orbit. Both of these areas, to- 

 gether with whole of clypeus, pale yellow, the labrum, mandibles, and 

 tubercles black. Antennae very long, distinctly surpassing the tegulae, 

 flagellum pale ferruginous beneath, dusky above, front of scape with a 

 yellow line. Head round, opaque, finely roughened, face but little con- 

 verging below. Legs black with the tibiae and tarsi yellow except for 

 a dark spot on posterior face of anterior tibiae and dark rings around 

 middle of intermediate and posterior tibiae. Thorax and abdomen 

 wholly black, the former dull and rather coarsely shallowly punctured, 

 the latter shining, its basal segment impunctate and following ones 

 but feebly punctured, segments 4-7 with short sparse white hair. 

 Wings somewhat darkened, nervures and stigma very dark brown. 

 Tegulae black. Enclosure of metathorax rugose on basal middle, else- 

 where smooth and opaque.
