Psyche 
[June 
Type: a male, U. S. N. M. No. 67802, from Colombia, Int. 
Choco, Istmina, Aug. 21, 1940. L. M. Murillo No. 5335. Two 
female paratypes from type locality, same data as type. 
Exochomus hisbinotatus Gorh. from Mexico to Guatemala is a 
smaller species (2 mm.) with proportionately larger spots and with 
the lateral margins of the elytra yellow. 
Exchomus hisbinotatus Gorham is not known to me in nature but 
only from the original description and figure in the Biologia Centrali- 
Americana. Therefore I am not sure that the species does belong to 
Exochomus. However I have not yet seen a species of Zagreus from 
a mainland locality north of Panama. Since E. hisbinotatus is re- 
corded from Mexico, British Honduras, and Guatemala it is probably 
not a Zagreus. The most northerly species of Zagreus is Z. ritchiei 
(Sicard) from the island of Jamaica. Exochomus jamaicensis Sicard, 
also from Jamaica, is correctly placed as to genus. 
Gurinus colombianus n. sp. 
Length : 4.3-4. 8 mm. Similar in dorsal coloration to C. coeruleus 
Mulsant but with the under parts and legs entirely pale reddish 
yellow. Head steel-blue above, piceous beneath and around mouth- 
parts, surface finely alutaceous, finely, moderately, and evenly punctu- 
late. Pronotum slightly more than twice as wide as length on median 
line (male) or twice as wide as long (female), median third steel- 
blue with lateral thirds reddish-yellow. Surface sculpture same as 
that of head except that the sides become more densely punctulate 
toward lateral margins. Scutellum small, black and polished. Elytra 
uniformly steel-blue above, the epipleura piceous. Surface sculpture 
same as that of median area of pronotum except toward apices where 
the punctulation becomes so minute as to be almost invisible under 
high magnification. Under parts pale reddish-yellow, shining and 
very sparsely punctulate, the punctures slightly coarser toward sides 
and apex of abdomen. Metacoxal arcs as in C. coeruleus Muls. Fifth 
sternite of male broadly and shallowly emarginate, the sixth with a 
V-shaped notch at apex; that of female evenly rounded at apex.
