554 SUPPLEMENT. 



in great part black, the legs piceous, the coxae rufo-ferruginous ; when fresh, probably with the upper 

 surface densely clothed with short golden pubescence (most of which is rubbed off in the single specimen 

 obtained), beneath with the sides densely, and the other parts sparsely, clothed with golden pubescence. 

 Head densely, finely punctate, broadly depressed in front, the sides of the front appearing raised ; antennae 

 extending beyond the hind angles of the prothorax, joint 3 twice as long as 2, 3 a little shorter and 

 narrower than 4 (10 and 11 broken off). Prothorax trapezoidal, at the base nearly twice as broad as 

 long, the sides slightly sinuate behind, the apex deeply emarginate on either side, the base trisinuate and 

 very distinctly crenulate, the hind angles divergent ; the surface densely, very minutely punctate, and with 

 some scattered coarser punctures on the disc, a rather broad space down the centre (which appears slightly 

 raised in front), and a small patch on either side of the disc before the middle midway between this and the 

 lateral margin, impunctate. Scutellum densely, very minutely punctate. Elytra four and one-half times 

 the length of the prothorax, and a little wider than its basal portion, subparallel to beyond the middle 

 and narrowing thence to the apex, the apical margin slightly sinuate, with the sutural angles sharp ; 

 finely seriate-punctate, the punctures placed in shallow grooves, the interstices feebly convex and densely, 

 very minutely punctate ; the humeri and the base of the third interstice considerably swollen. Beneath 

 sparsely, the propleurse and sides of the metasternum closely, punctate, the punctures on the propleurae 

 exceedingly fine. 

 Length 13|, breadth 4g millim. 



Hab. Mexico, Cordova [Salle). 



One specimen, placed with the series of Hypodesis sericea in the Salle collection, an 

 insect somewhat closely resembling it in general appearance. 0. suturalis may be at 

 once separated from the two other known species of the genus by the short trapezoidal 

 thorax and peculiar coloration. 



ATRACTOSOMUS (p. 297). 

 Atractodes, Candeze, Cat. Method. Elat. p. 63. 



Dr. Candeze, in his 'Elaterides Nouveaux,' v. p. 72 (1893), has recorded a species of 

 the genus, under the name of A. illinitus, as from " Yucatan " : the reference to 

 Yucatan, he informs me, is incorrect, the insect being from Merida, Venezuela. 



ANOPLISCHIOPSIS (p. 301). 



Anoplischiopsis lineatocollis (p. 303). (Tab. XXIV. fig. 8, e .) 

 To the localities given, add: — Costa Rica (coll. Janson); Panama, Volcan de 

 Chiriqui 2500 to 4000 feet (Champion). 



The description of this species was based upon a small, pallid, somewhat immature 

 female example. Additional specimens have since been detected, and they differ 

 greatly from the type in colour, and also in being more elongate. The four examples 

 ( 6 and 2 ) from the Volcan de Chiriqui have the head, a median vitta on the thorax 

 (narrowed in front and behind), and the tips of the hind angles, the scutellum, and a 

 broad sutural stripe on the elytra (widening to a little beyond the middle, and narrowing 

 again behind), as well as a narrow marginal stripe extending forwards to the middle, 

 and the apex to a greater or less extent, black, the under surface also being black, with
