1912] • Cockerell — New Bees from Brazil 59 



Diadasia murihirta sp. nov. 



Male. Length about 11 mm.; black, the head and thorax with rather dense 

 hair, which is warm ochreous above (fuscous on scutellum, and slightly so on disc 

 of mesothorax) and white below, the transition from one color to the other quite 

 gradual; small joints of tarsi ferruginous; antennae short for a male, the flagellum 

 obscurely reddish beneath; clypeus densely covered with light hair; mesothorax 

 with small but strong and rather close punctures; hind femora incrassate but not 

 at all subglobose; spurs piceous (in D. parahybensis they are cream-color); hind 

 basitarsus curved, red at apex but not prolonged; tegulse fuscoferruginous, pallid 

 at sides; wings moderately dusky (not reddish as they are in D. sumichrasti vul- 

 pihirta); abdomen with pale ochreous hair on first segment, the other segments 

 with very short and thin black hair (obscure brown on basal half and sides of second), 

 and broad dense apical ochreous hair-bands; sixth ventral with a large median 

 hair-tuft. 



Hub. — Independencia, Parahyba, Brazil, 2 males (Mann & 

 Heath). In Friese's table runs to facialis Friese, diflfering in the 

 total lack of light face-markings. In the North American table 

 it runs to the Mexican D. sumichrasti (Cr.), but the hair is less 

 brightly colored, while the second s. m., is broader above than 

 in sumichrasti, and receives the first r. n. nearer the apex. 



Diadasia sumichrasti vulpihirta subsp. nov. 



Female. Exactly like D. sumichrasti (one of Cresson's cotypes compared) 

 except that it is somewhat larger, the scape is largely red, and the flagellum is 

 partly red beneath, the color especially bright on the second joint and apex of the 

 first. There is a strong contrast between the bright fox-red hair of the mesothorax 

 and region about the tubercles, and the grayish-white of pleura. The abdominal 

 bands are broad and bright ochreous. The mouth-parts are as follows: maxillary 

 palpi 6-jointed, joints measuring in /j'- (1.) 224 (2.) 416 (3.) 464 (4.) 272 (5.) 176 

 (6.) 176; apex of second joint, and all of third, with a dense brush of hair on one 

 side; last joint very slender; blade of maxilla about 2400 ,'J- long, about 160 broad 

 near middle, and about 352 near base; maxillary comb very well developed, with 

 about 23 sharp teeth; paraglossse linear, reaching to a little beyond middle of first 

 joint of labial palpus; labial palpi with first joint about 1170 P- long and 192 broad, 

 second 1010 long; third (arising laterally 160 //. from end of second) 176 long; 

 fourth 160. Labrum about 1360 p- broad and 800 long, apex very obtusely angled, 

 the apical margin with strongly fimbriate hairs. 



Hab. — Baixa Verde, Rio Grande do Norte, Brazil {Mann).
