Bees and a new ProctotnjiiiJ. 201 



entirely black ; tegula3 ])iceous ; wings strongly dusky ; 

 femora black, except more or less at a[)(X, tibiai and tarsi 

 yellow, the small joints of the tarsi infuscatcd ; abdomen 

 black, closely and distinctly punctured. 



Ilab. Mexico ; further particulars unknown (Baker collec- 

 tion, no. 1785) *. 



The black scutellum distinguishes it from most of the 

 Mexican species; 1 do not know of any close ally. In my 

 table in ' Entomologist,' -A-ug. 1898, it runs to P. riujosula, 

 Ckll., but_it is quite distinct from that. 



CceUoxys angelica, ^). n. 



? . — Length about 9^ mm. 



Entirely black, including the legs; pubescence white; 

 tegular dark brown; wings with the apical half dusky; 

 scutellum with the lateral teeth slender and somewhat 

 hooked, no median tooth or tubercle; concavity of first 

 abdominal segment bounded by a distinct rim, behind 

 which is a narrow white hair-band; segments 1 to 5 with 

 narrow apical hair-bands ; transverse grooves on segments 

 2 and 3 broadly interrupted in the middle ; apical dorsal 

 segment rather broad, pointed (the {)oint not at all up- 

 turned), not notched, but rather suddenly depressed about 

 tlie middle, the depressed apical part with erect hairs; last 

 ventral segment surpassing the dorsal, broad, with the margin 

 ciliated with dark bristles, the apex not notched, but having a 

 minute tooth-like prominence ; penultimate ventral segment 

 with strong punctures, and no little ones between. 



Ilab. Los Angeles, California {Dr. A. Davidson) . 



Allied to C. mode&ta, Smith, and C. gilensis, Ckll., but 

 easily known from these by the last dorsal segment having 

 no upturned point. From C. apacheorum, Ckll., it is known 

 by its smaller size, apical ventral plate with a little projec- 

 tion, and penultimate ventral segment without little punctures 

 interspersed among the large ones. 



Triepeolus wyomincjensis, sp. n. 



$ . — Length just over 11 mm. 



lilack, including the antennte, leg.'^, and their spurs; 

 pubescence greyish creamy, pure white on fai;e ; clypeus 



* Mr.'^E. S. C4. Titus, who has access to Mr. Baker's uote-bouk, informs 

 nie that no. 1785, the number attached to the type of Prosopis crenulaUi, 

 signifies that it was collected by H. H. Hyde in the autumn of 1895, by 

 " fcweeping &c.," at Medellin, State of Vera Cruz, Mexico.
