45. Strongylium cinctum. (Tab. XV. fig. 24, 2 -) 
Strongylium cinctum, Makl. Monogr. p. 229; Act. Soc. Fenn. viii. part 1, p. 337°. 
Hab. Muxtco, Cordova (Sallé!), Cerro de Plumas, Misantla (Hoge). 
If I have rightly identified this species, S. conctum is at once separated from the 
allied forms by the exceedingly close, shallow, uniform punctuation of its regularly 
convex thorax. The elytra are nigro-zneous in tint, with the base and the lateral 
margins to beyond the middle red. The general shape is linear-elongate. 
An example from Misantla is figured. 
46. Strongylium marginale. (Tab. XV. fig. 25, ¢ .) 
Strongylium marginale, Mikl. Monogr. p. 280; Act. Soc. Fenn. viii. part 1, p. 338°. 
Hab. Mexico, Cordova (Sallé'). 
A long and narrow species; the thorax usually deeply impressed on each side of the 
disc in the middle; the elytra very long and cylindrical and with the apices some- 
what produced, testaceous in colour, with a broad obscure bluish-violet sutural stripe 
extending from a little below the base to the apex and there confluent with a narrow 
similarly-coloured marginal stripe which extends upwards nearly to the shoulders. 
{+ Eyes larger, subapproximate. 
47. Strongylium limitatum. 
Strongylium limitatum, Makl. Monogr. p. 234; Act. Soc. Fenn. viii. part 1, p. 342°. 
Hab. Muxtco (Deyrolle 1), Cordova (Sallé), Cerro de Plumas, Misantla (Hoge). 
S. limitatum is separated from its rather numerous allies by its narrow form; the 
large and approximate eyes; the very short thorax, the sides of which are toothed in 
the middle and the anterior angles prominent; and the sides and base of the elytra 
more or less broadly red. | 
48, Strongylium suturale. (Tab. XVI. fig. 5, ¢.) 
Strongylium suturale, Mikl. Monogr. p. 229; Act. Soc. Fenn. viii. part 1, p. 337°. 
Hab. Mexico, Cordova (Sallé1); GuateMaLa, Panzos and San Juan in Vera Paz 
(Champion). 
A single female example in the Sallé collection, labelled S. limitatum, is perhaps 
referable to this species. Two small male examples from Guatemala differ from the 
description in having the thorax more coarsely and closely punctured; these specimens 
are 62 millim. only in length. S. suturale is allied to S. limitatum in its approximate 
eyes, but differs in the less prominent anterior angles and the more rounded sides (not 
armed with a small tooth) of the thorax. 
The example from Panzos is figured.
