me agree so well in the differences pointed out below that I am compelled to treat the 
insect as specifically distinct. The head is not marked, either posteriorly or anteriorly, 
with black (thus differing from several species described by Lacordaire, e. g. L. septem- 
punctata, L. septem-plagiata, &c.) ; the antenne are pale or pale fuscous (not black as 
in the allied species); and the elytra in the typical form have a black anchor-shaped 
patch connected at the suture with a broad posterior band (resembling in this respect 
L. dorsalis, L. gracilis, and allied forms, in which, however, these marks are blue). 
The principal difference between L. ancoralis and L. hexastigma and its varieties is to 
be found in the pale testaceous legs and tibie, this coloration being constant in all the 
specimens from Bugaba; and in the basal depression of the elytra being very shallow. 
The var. a. resembles closely in the markings of the elytra L. hexastigma, and can only 
be separated by the colour of the antenne and legs; while var. 6., although agreeing in 
every other way with the type, is entirely devoid of any black markings. In the costate 
apical interstices and the deep punctures of the elytra this species closely resembles 
LL. hexastigma. 
45 (s). Lema laticollis. 
Testaceous, the antenna, the lower part of the face, and the tibiz black ; thorax subquadrate; elytra strongly 
punctate-striate, the suture, a spot at the shoulder, another before the middle, and a third near the apex, 
black. 
Var. Elytra with the suture black towards the base only ; the two posterior spots obsolete.

Hab. Mexico, Cordova, Vera Cruz (Sal/é). 
Four specimens. J. laticollis cannot be treated as a variety of L. heaastigma, on 
account of the following differences:—The clypeus and the labrum are black; the 
thorax is less elongate (being slightly broader than long), and its sides are but very 
moderately constricted; the elytra (though marked and punctured in the same way as 
in L. hewastigma) have their basal depression shallower; the underside and the femora 
are entirely testaceous or flavous; and the posterior femora extend very nearly to the 
end of the abdomen. The ninth row of punctures on the elytra is, as in L. ancoralis, 
largely interrupted and costiform. 
45 (c). Lema palmeri. 
Black ; antenne very short, the apical joints obscure fulvous ; thorax finely punctured, bi-impressed, the sides 
black, the rest of the surface testaceous; elytra testaceous, deeply punctured, the suture and a shert 
humeral streak, black; legs testiaceous, the femora with a black spot. 
Length 2 lines. 
Head impunctate ‘at the vertex, black, the lower portion rugose, covered with pubescence ; antenne extremely 
short, not extending beyond the base of the thorax, all the joints short, the first and the terminal four 
joints fulvous, the others black; thorax subquadrate, testaceous, the sides black, the basilar sulcation 
well-marked, the surface with a double row of punctures on the disc, some scattered punctures near the 
anterior angles, and two short longitudinal fovee near the anterior margin; scutellum black; elytra 
without basal depression, deeply and closely punctate-striate, the ninth row entire, the interstices slightly
