PLATYDEMA. 195 
24. Platydema bisignatum. (Tab. VIII. fig. 18.) 
Platydema bisignatum, Chevr. Petites Nouv. Ent. ii. p. 181". 
Hab. Mexico (Sallé) ; Guaremana, Capetillo 3000-5000 feet, San Geronimo ( Cham- 
pion).—CotomBia, Cartagena! (coll. F. Bates). 
This species will be easily recognized from our figure, which is taken from an example 
from Capetillo. | 
Central-American specimens agree with the Colombian. type, except that they have 
the elytra more finely and rather more shallowly punctate-striate, the punctures placed 
closer together ; but in a long series of examples I find considerable variation in this 
respect. P. erythropterum *, Chevr., from Bogota, is allied to this species, the elytra 
being similarly coloured, but at once separated by the very coarsely punctate-striate 
elytra (the punctures distant one from another) and convex interstices. 
I found P. disignatum in large numbers on the forest-clad slopes of the Volcan de 
Fuego in the vicinity of the sugar-plantation of Capetillo; one or two examples only 
from the other localities. 
25. Platydema hogei. (Tab. VIII. fig. 19.) 
Elongate ovate, moderately convex, deep black, opaque. Head shallowly, finely, and closely punctured, the 
anterior half red, the epistoma well-defined posteriorly by a transverse impression ; antenne black, the 
three or four basal joints, and the outer half of the apical one, red, joints 7-10 transverse ; last joint of 
the maxillary palpi securiform ; prothorax narrowing from the base, the sides feebly rounded (in some 
examples almost straight), the apex deeply emarginate, the anterior angles prominent, obtuse, the base 
strongly bisinuate, the surface shallowly, finely, and evidently punctured (a little more diffusely than the 
head); elytra long, regularly punctate-striate (the punctures shallow, and not closely placed), the 
interstices smooth, with a broad transverse subangular red band (not reaching the suture or outer margin) 
on each side before the middle, and a still broader but oblique red band (starting from the outer margin 
and confluent with the other at the suture) on each side some distance before the apex, in some examples 
the outer margin from the second band to the extreme apex also red ; legs piceous, the tarsi and knees 
lighter; beneath shining, sparingly and rather coarsely punctured, the ventral surface at the sides 
longitudinally wrinkled and irregularly punctured. 
Length 6-8 millim. 
Hab. Mexico (Sallé), Jalapa, Esperanza (6ge). 
Captured in abundance by Herr Hoge at Jalapa. Allied to P. maculosum, Lap. & 
Brullé, from Brazil, but with the second band on the elytra placed some distance before 
the apex (not at the apex itself, as in that species), &c. 
26. Platydema monilicorne. 
Platydema monilicorne, Chevr. Petites Nouv. Ent. i. p. 186°. 
Hab. Mexico}. 
Unknown to me. ‘The following is the description :—“ Oblongum, convexum ; 
* M. Chevrolat (op. cit. p. 187, nota) states that this species is also found in Mexico, but probably in error 
for the allied P. bisegnatum.
