398 MR. MARTIN JACOBY OX NEW SPECIES OP [DeC. 13, 



banded form as the typical one, and that in which the bands 

 occupy the entire disc of the elytra as the variety. I cannot 

 distinguish a specimen in any way from the others, having the 

 antennee, underside, and legs fulvous, 



LaCTICA MACULICOIiLIS, sp. n. 



Testaceous, the head and a spot at the anterior part of the 

 thorax rufous ; elytra elongate, scarcely perceptibly punctured, 

 testaceous, a transverse band at the base rufous. 



Leng-th 4 millim. 



Head entirely impunctate, rufous, frontal elevations absent, 

 carina elongate, strongly convex, eyes very large ; antennfe fulvous, 

 long and slender, the third joint slightly longer and thinner 

 than the second ; thorax about one half broader than long, the 

 sides straight, the basal sulcus broad and rather deep, the surface 

 testaceous, impunctate, with a rufous spot at the middle of the 

 anterior margin, anterior angles obtuse, thickened ; scutellum 

 testaceous ; elytra not perceptibly punctured, even under a strong 

 lens, elongate and parallel, testaceous, with a transverse rufous 

 band at the base extending to the lateral margins, this band 

 scarcely occupies a third portion of their length ; underside and 

 legs pale testaceous. 



Hah. Peru. 



Of less than half the size of L. rvfohasalis Jac. and distinguished 

 by the coloration of the head and thorax. 



Lactica posticata, sp. n. 



Head, the basal joints of the antennae, the thorax, and the 

 anterior femora ilavous ; elytra dark violaceous, finely punctured 

 anteriorly ; the posterior legs blackish. 



Length 3 millim. 



Head impunctate, the frontal elevations feebly raised ; cai-ina 

 short, not widened in front ; antennae long and slender, black, the 

 lower three and the base of the fourth joint flavous, third and 

 fourth joints equal ; thorax about twice as broad as long, the sides 

 nearly straight, the anterior angles oblique, the basal sulcus 

 sti'aight and deep, bounded laterally by very deep perpendicular 

 grooves, the surface impunctate, flavous ; scutellum flavous ; elytra 

 without a trace of a basal depression, violaceous, with indistinct 

 rows of fine punctures at the anterior portion, extremely sparingly 

 and finely punctvired near the apex ; the breast and the anterior 

 femora flavous ; the abdomen, the posterior femora, and the tibiae 

 and tai'si piceous. 



Hah. Peru. 



Closely allied to L. elegantula Har. (Coleopt. Hefte, xiv. p. 16) ; 

 but the frontal elevations of the head feeble, the latter without 

 punctures, the third and fourth joints of the antennae of equal 

 length, the elytra without any basal depression and some fine 

 punctures posteriorly, and the legs differently coloured. L. holi- 

 viana Jac. is of double the size and strongly punctured.
