ADEPHAGA. 



■ 



An examination of a long series of examples from various localities shows this to be a 

 very variable species. In size it ranges from 2 J-4 lines. In colour it is normally ferru- 

 ginous tawny, with two fuscous spots on the disk of the thorax, and the elytra, excepting 

 the margins, fuscous with a brassy tinge ; but the fuscous colour sometimes spreads over 

 the whole surface, and, on the other hand, the thorax is sometimes clear ferruginous. 

 The normal sculpture of the elytra is confined to a deeply impressed sutural and two 



marginal strise; but the disk is sometimes rather strongly punctate-striate, and all 

 intermediate variations occur. The species is distinguished from the closely allied 

 B. nitidus (Dej.) of California only by its more elongate form and its narrower thorax.

Acupalpus circumdatus, Bates, Proc. Zool. Soc. 1878, p. 593 \ 



" Elongato-oblongus, castaneo-fuscus; antennis basi, palpis, pedibus margineque angusto elytrorum flavo- 



testaceis; thorace postice valde angustato, laovi, basi utrinque haud foveato, parum punctato, lateribus 



antice fortiter rotundatis, postice sinuatis, angulis posticis prominulis rectis ; elytris striis modice impressis* 

 baud punctatis, striola scutellari nulla. 

 « Long. 21 lin." 



Eab. Mexico, Vera Cruz (Boucard) 1 , Cordova, Toxpam (Salle) ; Guatemala, Duenas, 



Torola (Champion). 



The pale yellowish border of the elytra very frequently widens behind into an apical 

 patch ; and the apical portion of the suture is then pallid. The base of the thorax on 

 each side varies much in its punctuation and is sometimes quite smooth. The third 

 elytral interstice bears the usual puncture near the second stria. 



The species is named Bradycellus ingratus in the Salle collection.

Var. longulus, paullo gracilior, thorace postice paullo magis angustato; supra nigro- yel castaneo-fuscus,

Closely allied to B. circumdatus^ but the thorax always much longer and more 

 narrowed behind, with hind angles almost effaced. In colour it varies much, from 

 tawny testaceous (immature %) to nearly black, with sutural and lateral margins (and 

 sometimes the humeral angles) of the elytra reddish ; but the great majority of the 

 specimens examined are as described in the foregoing diagnosis. 



The species is very closely allied to the North- American B. rupestris (Say) ; and
