260 PHYTOPHAGA.—SUPPLEMENT. 
36. Lactica crassicornis. 
Pale fulvous or testaceous, the antenne (the basal three joints excepted) black; thorax impunctate, the basilar 
groove deep; elytra very finely punctured. 
3. Basal joints of the antenne robust, the others with a fringe of long hairs. 
@. Elytra with two longitudinal coste at the sides, the antenne normal. 
Length 13 line. 
3. Head with a few deep punctures near the eyes, the middle portion triangularly raised, the clypeus 
acutely raised, but not broad, the apex of the mandibles black; antenne extending to a little beyond the 
middle of the elytra, black, the basal three joints fulvous, the first joint long, strongly thickened, the 
second short, the third and fourth equal, the others more slender and elongate, with a fringe of black 
hairs on their inner margin; thorax twice as broad as long, the sides very little rounded, the anterior 
angles somewhat oblique, the surface impunctate, with a transverse deep basal sulcus, which is sinuate 
at the middle and interrupted by a deep longitudinal groove at the sides; elytra with an obscure depres- 
sion below the base, the punctures only visible under a very strong lens; Jegs rather robust. 
Hab. Mexico, Acapulco in Guerrero, Tapachula in Chiapas (/ége). 
This Lactica will not be difficult to recognize in either sex, the antenne being robust 
and hairy in the male, and the elytra having two cost in the female; these coste are 
very strongly raised, and they arise from a common stem at the shoulder, and are 
joined at the apex; the raised middle portion of the head is another peculiarity of 
this species. 
37. Lactica quadrinotata. (Tab. XLI. fig. 21.) 
Ovate, pale testaceous ; the antenne, tibie, and tarsi piceous; head and thorax obscure fulvous, the basal 
sulcus of the latter almost obsolete ; elytra extremely finely punctured, testaceous, with four small black 
spots placed transversely along the basal margin. 
Length 2 lines. 
Head entirely impunctate, fulvous, the eyes large, a single deep puncture in front of their inner margin, the 
clypeus strongly raised and widened anteriorly ; the antenne extending to about the middle of the elytra, 
piceous, the basal two joints fulvous, shining, the third joint much shorter than the fourth; thorax more 
than twice as broad as long, the sides straight, the anterior angles oblique, the surface entirely impunc- 
tate, the basal sulcus almost obsolete, the lateral impression at each end of it a little more distinct ; elytra 
ovate, pale testaceous, very minutely punctured, each with two small round blackish spots close to the 
basal margin; underside and legs testaceous, the upper edge of the femora at the apex and the tibie and 
tarsi more or less piceous; the first joint of the posterior tarsi rather longer than the following two joints 
together. 
Hab. GuatemaLa, Chiacam in Vera Paz (Champion). 
One specimen. 
38. Lactica hypocrita. 
Lactica hypocrita, Harold, Col. Hefte, xiv. p. 22’. 
Hab. Panama, Bugaba in Chiriqui (Champion).—Co.ompta |. 
The single example obtained at Bugaba agrees in every respect with the author’s 
description. L. hypocrita may be known from the other species of Lactica from our 
region by the elytra having the anterior portion fulvous and the posterior portion 
black ; it is only one line and a half in length.
