ART. 8. BEES FROM VICTORIA, MEXICO COCKERELL. 3 



COELIOXYS TOLTECOIDES, new species. 



Male. — Length about 10.5 mm. ; black, with red legs (except 

 tarsi), tubercles and tegulae; first three ventral abdominal segments 

 obscurely stained with red; pubescence white, slightly yellowish on 

 thorax above; face with white hair; mandibles black (red in C. 

 tolteca) ; antennae black, scape red in front; cheeks covered with 

 white liair, the depressed space below also hairy; mesothorax with 

 exceedingly large partly confluent punctures; axillary spines stout 

 and well-developed; scutellum with large partly confluent punc- 

 tures, subconically produced but not dentate at apical middle; 

 pleura strongly punctured, thinly hairy ; anterior coxae with very 

 short red spines; tarsi black, the anterior ones reddened basally; 

 wings somewhat dusky, especially the broad apical margins; stigma 

 red, ner^aires black; first recurrent nervure almost meeting inter- 

 cubitus, joining extreme base of second cubital cell; abdomen shin- 

 ing, the segments sparsely punctured in middle, more densely at 

 sides, second segment with dull closely punctured areas sublaterally ; 

 first three segments with thin marginal band of white hair; seg- 

 ments 2 to 5 with interrupted subbasal white hair-bands, successively 

 less narrowly interrupted caudad; caudal end with sharp lateral 

 spines, and sharp, widely separated, inferior apical ones, but upper 

 apical represented by a short more or less trilobed structure, giving 

 the abdomen a broadly truncate appearance; fourth ventral seg- 

 ment with two short apical spines. Hair of eyes short. 



One male ; Victoria, Mexico, March IG. 



This is so similar to C. tolteca that I thought at first it must be 

 its male, but the great differences in the scutellum and wings nega- 

 tive such an idea. Among the United States species there is a cer- 

 tain affinity with C. texana Cresson, but it is not close. 



Type.—C?it. No. 25581, U.S.N.M. 



MELISSODES TKISTIS Cockerell. 



One male. Described from New Mexico. Also known from Ari- 

 zona and from Juarez, Mexico. 



MELISSODES MASUCA Cockerell. 



One male. Described from Texas ; new to Mexico. The specimen 

 differs from the type in having the posterior side of the hind femora 

 red only at the apical end, and the nervures dark. Similar varia- 

 tion occurs in specimens from the extreme south of Texas. 



CHALEPOGENUS APICALIS (CreBson). 



One female. Described as Tetrapedia apicalis, from " Mexico." 

 Friese has recorded it from Orizaba. In our specimen the second 

 submarginal cell receives the recurrent nervure a short distance
