; subcrescentic, with anastomosing rugae.......... herbstiellus Friese. 
Mesothorax weakly punctured; flagellum testaceous beneath; disk of 
propodeum shorter, shining, plicate on the base only. exiguiformis Ellis. 
Hauictus (CHLORALICTUS) SPINOLAE (Reed) 
Since no recent or full description of Halictus spinolae (Reed) is readily 
available in this country, the writer gives the following: 
Female—About 4.5-5 mm. long; head and thorax olive green; abdomen 
black; pubescence white, rather sparse. Facial quadrangle longer than 
broad; orbits converging below; antennae dark, flagellum testaceous beneath; 
front very closely punctured, giving an almost granular appearance; sides of 
face with more scattered punctures; supraclypeal area and upper part of 
clypeus microscopically tessellate, sparsely punctured, with a brassy reflec- 
tion; lower half of clypeus black; mandibles black. Mesothorax dull, finely 
tessellate and very closely punctured; punctation of scutellum similar to that 
of the mesuthorax, two polished spots on the disk; disk of propodeum with 
fine, irregularly anastomosing rugae, making a reticulate surface; tegulae 
dark brown, impunctate; truncation well defined laterally. Abdomen 
obovate, shining, impunctate; pubescence sparse, especially on the first 
segment; apical margins of segments narrowly testaceous. Wings clear, 
anterior wing 3.5 mm. long; stigma and nervures testaceous; second sub- 
marginal cell higher than broad, receiving the first recurrent nervure near the 
apex; third submarginal gently contracted above, about one and one-half 
times as long as second on the marginal. Legs black with dull white hairs; 
hind spur pectinate with four moderately long teeth. 
The following locality is new: 1 female (Foothills) Lima, Peru, December 5 
(C. H. T. Townsend). 
The description given above is based on this Peruvian specimen, which was 
found to be identical with a specimen of spinolae from Chile, determined by 
C. Schrottky. 
BOTANY.—New or little known Melastomataceae from Venezuela 
and Panama. H. Prirrimr. 
In the course of my investigations on the flora of Venezuela, in 
which I have been so efficiently helped through the codperation of my 
friend Dr. Alfred Jahn, I am constantly coming across plants which 
have never been catalogued. These are of course more interesting 
to me when they belong to groups with which I have become familiar 
during former studies.'
