410 Descri'i'tions and Records of Bees. 



short; antennje short, flagellum dull reddish beneath except 

 at base ; mesothorax shining, s[)arsely punctured in middle ; 

 area of metathorax triangular, not polished ; tegulfe clear 

 rufo-testaceous. AVings strongly reddened, dusky on apical 

 margin, stigma and nervures ferruginous. Legs with pale 

 hair ; anterior tibiee and tarsi ferruginous in front. First 

 abdominal segment with long pale ochreous hair, the margins 

 of segments 1 to 5 with entire white hair-bands, only mode- 

 rately broad ; venter polished. 



$. — Similar, but more robust; fimbria on last two seg- 

 ments of abdomen dark chocolate. 



Variety parva, var. u., (^ . — Uniformly smaller ; anterior 

 wing 7 mm. long. 



Carcarana, Argentina {L. Bruner, 35 ; the ? 78 ; var. 

 parva, 48). U.S. Nat. Museum. 



I separated the var. 2^o.rva (3 cJ ) as a distinct species on 

 accoimt of the uniformly small size; but there are a))parently 

 no good structuial characters. Probably the large and small 

 races visit different flowers. Year's ago, I think before 

 Lonchopria was published, Mr. J. C. Crawford examined the 

 nioutli-part?, and attached a label, " ColletidjB, u. gen.?.'^ 

 The palpi, from Mr. Crawford's mount (male of larger race), 

 measure as follows in microns : — Labial palpi, joints (1) 112, 

 (•>) 96, (3) 96, (f) 128 ; maxillary palpi, joints (1) 144, 

 (2) 80, (3) SO, (4) 80, (5) 80, (6) 128. The palpi are pale 

 and much more delicate than in L. ahpe.v, Ckll. 



This species may be compared with L. nivosa, Vach., but 

 is easily known by the reddened wings and finely and densely 

 punctured ? clypeus. 



Camptopoeum reedi, sp. n. 



$ (type). — Length about 8 mm. 



jiobust, black, not at all metallic ; head, thorax, abdomen, 

 and legs with abundant pale hair^ distinctly ochreous-tinted 

 on head and thorax above ; eyes grey ; face broad ; labrum 

 transversely striate ; face with creamy-white markings as 

 follows : — large triangular mark in middle of clypeus, supra- 

 cljpeal transverse band, and more or less L-siiaped lateral 

 face-marks, the upper arm of the L (along the orbit) suddenly 

 narrowing at about level of antennae, and above that linear ; 

 flagellum ferruginous beneath except at base ; vertex dull ; 

 mesothorax and scutellum shining ; base of metathorax with 

 a transverse obtuse })olished ridge ; teguke piceous. Wings 

 hyaline; stigma reddish, veiy small; b. n. falling short of
