STRONGYLIUM. 367 
have examined the sixth (and usually hidden) ventral segment projects beyond the fifth 
segment and is distinctly visible. 
A typical female from Senahu and a male of the variety y from Sinanja are figured. 
44, Strongylium misantle. (Tab. XV. fig. 23, 3.) 
Moderately elongate, not very convex, metallic green or bluish-green. Head very closely and coarsely punc- 
tured (in some examples confluently, in others more sparingly so, between the eyes), the intraocular space 
sometimes longitudinally grooved in the middle, the eyes rather small and widely separated; antenne 
rather slender, widening a little outwardly, in the male long, reaching to one third of the length of the 
elytra, in the female much shorter, joints 3 and 4 long, subequal, the penultimate joints much longer than 
broad, the extreme apex often testaceous; prothorax strongly transverse in the male, rather longer in the 
female, moderately convex, the base feebly bisinuate, the apex straight, the sides a little rounded about 
the middle and slightly narrowing in front, the anterior angles obtuse, the hind angles subrectangular or 
acute, the basal fovess deep, the disc irregularly and obliquely impressed on each side and sometimes 
shallowly canaliculate towards the base, the surface rather uneven and very coarsely, closely, and irre- 
gularly punctured, the punctures sometimes shallower and more scattered in the female; scutellum 
triangular, impressed in the middle behind, variable in colour but usually obscure red; elytra moderately 
long, not very convex, comparatively broad, deeply and very coarsely striate-punctate (the punctures 
approximate and more or less transverse), the interstices rather convex towards the sides and strongly 
so at the apex, smooth, the surface red or reddish-testaceous, with a metallic green or bluish-green very 
broad sutural stripe extending from a little below the scutellum to the apex, the stripe usually narrowing 
towards the base; beneath bright greenish-zeneous, almost glabrous, sparingly punctured ; the anterior and 
intermediate tibia a little curved, the inner edge of the former slightly sinuous, and the posterior tibie 
somewhat strongly sinuate, in the male, the fifth ventral segment unimpressed as in the female. 
Length 9-11} millim.; breadth 33-43 millim. (3 9.) 
Hab. Mexico, Misantla (Hoge), Panistlahuaca (Sallé); GuaTemata, San Juan in Vera 
Paz (Champion). 
Var. a. The prothorax suffused with red on each side of the disc; the rest as in the type. 
Hab. Guatemaua, Zapote (Champion). One female example. 
Var. @. The elytra narrowly red at the sides for two thirds only of their length; the prothorax marked as in a. 
Hab. Guatemata, Capetillo (Champion). One male example. 
Var. y. The elytra entirely of a violaceo-cupreous tint ; the prothorax marked asin aand GB. (Tab. XVI. fig. 3, 3.) 
Hab. Guatemaa, Capetillo (Champion). A single male. 
Iam unable to refer this insect to either of the species described by Maklin. It is 
perhaps nearest allied to S. discoidale, and like that species usually has the scutellum red 
in colour; but is separated by the different system of coloration of the elytra, by the longer 
antenne, by the thorax being wider at the base, &c. From S. laterale and its allies it is 
distinguished by its shorter and more depressed form, comparatively shorter and broader 
and more coarsely striate-punctate elytra, &c. Found in abundance by Herr Hoge at 
Misantla; the single example in the Sallé collection is labelled S. cinctwm, Makl., but 
does not agree with the description of that species. 
The specimens from Guatemala are somewhat aberrant, but I am unable to satis- 
factorily separate them. We figure an example of the typical form from Misantla, and 
one of the var. y from Capetillo.
