middle) and the apex reddish testaceous, the lateral margins, epipleure, suture (and scutellum ) red; legs 
red; beneath shining, very sparingly and finely punctured. 
Length 6-63 millim. 
Hab. Mexico, Jalapa (Hoge); Guatemaua, Cerro Zunil (Champion). 
Four examples. Allied to P. biplagiatum, but readily distinguished by the entirely 
red antenne and other characters given above. 
42. Platydema dimidiatum. (Tab. IX. fig. 7.) 
Platydema (?) dimidiatum, Chevr. Petites Nouv. Ent. ii. p. 194’. 
Hab. Mexico 1, Cordova (Saldé). 
The following are varieties of this species :— 
Var. a. The broad transverse black band a little beyond the middle of the elytra not reaching the suture, and 
in the form of a large separate spot on each; the subapical patch in the form of an oblique stripe (united 
at the suture behind) parallel with the lateral margins. 
Hab. Mexico, Cordova (Sallé, Hoge); GuaTEMALA, Sinanja (Champion). 
Var. b. The two sub-basal spots on each elytron united, the transverse band broader and more angular on its 
anterior and posterior margins, the base broadly margined with black for about half its width, and the 
marginal streak (sometimes obsolete in var. a) longer. , . 
Hab. GuatemMata, Zapote (Champion). One example. 
A variable, and apparently rare, species; seven examples only are before me. The 
antenne usually have the four or five basal joints, and the extreme apex of the apical 
one, clear red; in the example from Zapote, which is somewhat discoloured, the two 
basal joints only are red. In all the specimens the head is unequally punctured, the 
anterior margin bearing a row of distinctly coarser impressions. 
A typical example from Cordova is figured. 
43. Platydema elegans. (Tab. IX. fig. 8.) 
Platydema (?) elegans, Chevr. Petites Nouv. Ent. ii. p. 195’. 
Hab. Mexico 1, Cordova (Sallé, Hoge), Jalapa, Esperanza (Hége). 
Seven examples are before me, in three of which the large black spot placed a 
little beyond the middle of each elytron extends inwardly, and, meeting at the suture, 
forms a broad transverse stripe. 
We figure a typical example from Cordova. 
44, Platydema lucens. (Tab. IX. fig. 9.) 
Ovate, moderately convex, bright reddish testaceous, shining. Head red, finely and not very closely punctured, 
the epistoma not defined from the front, and with a row of rather coarse punctures along its anterior 
margin ; antenne with the five basal joints, and the outer half of the apical one, testaceous, the rest 
piceous, the ninth and tenth joints transverse; apical joint of the maxillary palpi securiform ; prothorax
