ton, La., June 13 which differ from the types in showing 
faint maculation similar to that in insularis and slightly 
coarser punctation of the prothorax. It is remarkable that 
F. M. Jones collected a specimen Aug. 21, 1931 on Martha’s 
Vineyard, Mass. This specimen, which is in the Boston 
Soc. Nat. Hist., has no maculation as in the types. Appar- 
ently this record cannot be accounted for by hurricanes, 
since the last one passed over Martha’s Vineyard in 1928. 
Lobiopa punctata new species 
Fig. 4. 
Oblong oval, rather strongly convex, shining, rufo-testa- 
ceous above and beneath. Head sparsely pubescent, closely, 
coarsely punctate; broadly impressed between the eyes; 
lobes over the insertion of the antennae more transversely 
produced than in the other North American species; labial 
palpi incrassate. Prothorax as emarginate in front as 
hrunnescens, therefore less emarginate than in the other 
North American species ; lateral margins narrowly explanate 
and evenly arcuate; hind angles broadly rounded and ob- 
tusely angled ; hind margin feebly bisinuate ; surface closely, 
coarsely punctate, with sparse pubescence and with sparser 
small setae. Prosternal process only slightly reflexed be- 
hind the coxae. Elytra with narrowly explanate, feebly 
arcuate lateral margins; eight rows of small setae; finely 
pubescent ; each elytron with two pale spots extending 
across anterior median agle, a transverse pale band across 
inner half at posterior third, and center somewhat darker. 
Beneath closely, coarsely punctate, finely pubescent. Length 
5.2-4. 5 mm., width 3. 1-2. 5 mm. 
Described from four males; holotype and paratype from 
Miami, Florida, March 11, 1924 in the collection of H. C. 
Fall ; one paratype from Miami, Florida, March 31 in the 
Van Dyke collection in the Calif. Acad, of Sciences; and a 
paratype from Balaclava, Jamaica, A. E. Wright, in the 
Mus. Comp. Zoology. 
This species is apparently closest to hrunnescens , particu- 
larly in the convexity of the body and degree of emargina- 
tion of the pronotum. It differs from hrunnescens in its 
larger size, much coarser punctation and pubescence, nar-
