Blake — Flea Beetles 
143 
First joint of hind tarsi long, claws appendiculate. 
Length 3. 1-3. 5 mm. ; width 1.5-1. 7 mm. 
Type male and 3 paratypes M.C.Z. Type No. 27798. 
1 paratype in U.S.N.M. Cat. No. 58724. 
Type locality. — Whitfield, Bine Mts., Jamaica, elevation 
4500 feet, collected in Ang. 1930 by P. J. Darlington. 
Remarks . — In coloration this is similar to L. violacea 
Jac. described from Guatemala and Panama. It differs 
from that species in being a little more elongate and with 
extremely fine punctation which is the same throughout, 
not disappearing at the apex as in violacea. The sculp- 
ture of the head with its distinctly marked frontal tuber- 
cles also appears different, and the sulcus across the 
prothorax is not sinuate at all but straight. 
Lactica porphyrea n. sp. 
Fig. 3 
From 2.5-3 mm. in length, ovate, shining yellowish or 
reddish with violet elytra and dark abdomen ; only faint 
traces of a basal sulcus across the prothorax most marked 
on each side at the limiting ends ; elytra distinctly and 
rather densely punctate. 
Head with interocular space over half its width, frontal 
tubercles and space between the antennal sockets some- 
what elevated with a depressed spot or area above the 
tubercles, the surface of the occiput and front and frontal 
carina densely and shallowly punctate and alutaceous ; a 
large puncture on either side of front near the eye. An- 
tennae more than half the length of the beetle, third joint 
shorter than fourth, remainder subequal and rather 
heavy. Prothorax fully twice as wide as long with arcu- 
ate sides and narrow explanate margin; surface smooth, 
polished and fairly alutaceous with sparse punctation; 
across base an ill marked and, in some specimens, very in- 
distinct trace of sulcus, the rather faint limiting depres- 
sions at either end the most distinct part of it. Scutellum 
usually deep reddish brown. Elytra with small humeri 
and a slight basal callosity, very shiny deep violet, with 
dense distinct punctation in basal half becoming smoother 
near the apex. Epipleura wide, gradually diminishing
