440 Descriptions and Records of Bees. 
short; antenne short, flagellum dull reddish beneath except 
at base ; mesothorax shining, sparsely punctured in middle ; 
area of metathorax triangular, not polished ; tegule clear 
rufo-testaceous. Wings strongly reddened, dusky on apical 
margin, stigma and nervures ferruginous. Legs with pale 
hair ; anterior tibie 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. n., 6 .—Uniformly smaller; anterior 
wing 7 mm. long, 
Carcarana, Argentina (LZ. Bruner, 35; the @ 78; var. 
parva, 48). U.S. Nat. Museum. 
I separated the var. parva (3 ¢) as a distinct species on 
account of the uniformly small size; but there are apparently 
no good structuial characters. Probably the large and small 
races visit different flowers. Years ago, I think before 
Lonchopria was published, Mr. J. C. Crawford examined the 
mouth-parts, and attached a label, ‘“ Colletidse, n. gen. ?.” 
The palpi, from Mr. Crawford’s mount (male of larger race), 
measure as follows in microns :— Labial palpi, joints (1) 112, 
(2) 96, (3) 96, (4) 128; maxillary palpi, joints (1) 144, 
(2) 80, (3) 80, (4) 80, (5) 80, (6) 128. The palpi are pale 
and much more delicate than in L. a/opex, Ckll. 
This species may be compared with ZL. nivosa, Vach., but 
is easily known by the reddened wings and finely and densely 
punctured ? clypeus. 
Camptopeum reed, sp. n. 
Q (type).—Length about 8 mm. 
Robust, 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- 
clypeal transverse band, and more or less L-shaped lateral 
face-marks, the upper arm of the L (along the orbit) suddenly 
narrowing at about level of antennze, and above that linear ; 
flagellum ferruginous beneath except at base; vertex dull ; 
mesothorax and scutellum shining; base of metathorax with 
a transverse obtuse polished ridge; tegule piceous. Wings 
hyaline ; stigma reddish, very small; b.n. falling short of
