EHTNCHOPHOEA. 



with a faint longitudinal median groove. Elytra moderately long, not or very little wider than the 

 prothorax, produced at the apex, the apices subexplanate, separately rounded, and distinctly dehiscent 

 at the sutural angle ; crenato-striate, the interstices somewhat convex and obsoletely uniseriate-punctate. 

 Beneath sparsely, finely punctate ; first Ventral segment with a shallow transverse impression in the 

 middle at the apex in both sexes. 

 Length 2±-3, breadth §-| millim. ( c? $ •) 



Hab. Panama, Volcan de Chiriqui 2000-3000 ft. (Champion). 





Six specimens. Recognizable by its large, downwardly-extended eyes, the separately 

 rounded apices of the elytra, and the ferruginous or fusco-ferruginous colour. In one 

 of the males the rostrum is shallowly grooved down the middle towards the base. The 

 median groove on the prothorax is more pronounced in the male, the disc being 

 completely unimpressed in two of the females obtained. The closely allied M. batesi, 

 WolL, has the apices of the elytra conjointly rounded, as in M, continaus.

5. Micromimus cribrosus, sp. n. (Tab. I. figg. 35, 35 a.) 



Elongate, subfusiform, somewhat robust, shining, testaceous. Head smooth ; eyes strongly transverse, oval, 



■ 



Scutellum smooth. Elytra moderately long, scarcely wider than the prothorax, very gradually narrowing 

 from the base, produced at the apex ; coarsely crenato-striate, the interstices feebly convex, almost 

 smooth, the seventh and ninth raised and confluent near the tip, together forming a prominent ridge 

 around the apical margin. Beneath coarsely punctured. Legs stout. 

 Length 3£, breadth 1 millim. ( $ .) 



Hab. British Honduras, R. Sarstoon (Blancaneaux). 



One specimen, perhaps a little immature. Separable from the other members of the 

 genus by its more robust build, the coarsely punctured upper and under surfaces, and 

 the prominent marginal ridge at the apex of the elytra. The eyes are relatively smaller, 

 more finely facetted, and less transverse than in M. nigrescens. 





Allied unnamed forms occur in the West Indies.

depressed, moderately large ; rostrum short, stout, feebly curved, cylindrical, closely, finely punctate. 

 Prothorax as long as broad, subcorneal, constricted in front, rounded at the sides posteriorly, subtruncate 

 at the base ; coarsely, somewhat closely, subuniformly punctate, unimpressed along the median line.

STENOMIMUS. 



Stenomimus, Wollaston, Trans. Ent. Soc. Lond. 1873, pp. 437, 480, 564, 622; Leconte, Proc. Am. 



Phil. Soc. xv. pp. 337, 339 (1876). 



* 



Allomimus, Leconte, loc. cit. xv. pp. 337, 339; Casey, Ann. N. York Acad. Sci. vi. p. 692. 



Stenomimus and Allomimus were both based upon single species — S. fryi, WolL, 

 from Brazil, and A. (Cossonns) dubius, Horn, from Illinois, — and one or two N. -American 

 forms have since been added to each of them by various writers. The numerous small 

 species now known from Central America * connect these two genera, the rather less 

 oblique scrobes of Allomimus ditbius being perhaps due to the very small eyes in that 

 insect. They have the head globose and almost smooth, and slightly depressed or
