16 PHYTOPHAGA.—SUPPLEMENT. 
more convex. . transverso-fasciata in regard to the elytral pattern is no doubt as 
variable as many of its allies, thus necessitating the examination of long series of 
specimens to distinguish between varieties and species. 
15 (a). Lema obliterata. 
Rufous, the antenne: and legs black ; thorax deeply constricted at the sides, impunctate; elytra convex, without 
basal depression, metallic blue, the punctures obliterated below the middle, the extremé apex obscure 
fulvous. 
Length 2 lines. 
Head constricted, impunctate, rufous, the eyes somewhat deeply notched, the lateral grooves deep; antennz 
entirely black, half the length of the body, the third joint slightly shorter than the fourth; thorax about 
as broad as long, deeply constricted at the middle, the anterior angles rounded, the surface impunctate, 
the basal sulcation not deep but distinct; scutellum piceous; elytra convex, subcylindrical, with an 
indication of a slight impression below the middle near the suture, the intrahumeral groove very short, 
the punctuation distinct at the base, but almost entirely obsolete from the middle, where it is replaced 
by slightly impressed stris, the apical margin fulvous, the ninth row of punctures entire; legs entirely 
black; underside rufous. 
Hab. Panama, David in Chiriqui (Champion). 
A single specimen. This species is distinguished from its allies by the elytra being 
almost without depression, and with the punctuation at the middle nearly obsolete, in 
connection with its apical fulvous margin and the black legs and antenne. 
15 (s). Lema cornuta. 
Lema cornuta, Fabr. Syst. Eleuth. i. p. 475"; Illig. Magaz. f. Insekt. iii. p. 159°; Oliv. Entom. vi. 
p. 741, t. 2. fig. 22°; Lac. Monogr. in Mém. Soc. Liége, iii. p. 382%. 
Hab. North America! 23 4,—Mexico, Tuxtla, San Miguel (Sallé); Guatemana, Las 
Mercedes (Champion). 
I cannot find any differences of importance to justify the separation of the specimens 
obtained in Mexico and Guatemala from one received from Texas contained in my 
collection. For the description of this species I must refer to Lacordaire’s monograph ; 
but the length given, 33 lines, is probably a mistake for 24 lines, the size of the 
examples before me. 
Lema biornata (p. 5). (Tab. IL fig. 1.) 
The reference to the Plate was accidentally omitted on p. 5. 
Lema confusa (p. 5). 
To the localities given, add :—Mextco, Pinos Altos in Chihuahua (Buchan-Hepburn), 
Ventanas and Presidio in Durango (forrer), Cordova, Tuxtla (Sallé), Cerro de Plumas, 
Jalapa, Tacambaro in Michoacan (Hoge), Orizaba (F. D. Godman & H. H. Smith),
