Hab. Dikoya. 



Shortly or rather broadly ovate, dark brown ; elytra with a 

 small well-defined dirty white spot on the middle of each ; 

 upper surface set with numerous short, erect black scales ; ros- 

 trum nearly as long as the prothorax, punctured at the base 

 and gradually smoother and ferruginous towards the apex ; 

 antennae testaceous ; prothorax very transverse, narrow at the 

 apex, rapidly expanding and rounded at the sides ; scutellum 

 round, elevated, smooth ; elytra a little broader than the pro- 

 thorax, callous at the shoulders, very indistinctly seriate- 

 punctate ; body beneath ferruginous, with pale scattered scales 

 imbedded in punctures ; legs short, dark brown. 



This species in a certain degree resembles Acalles roboris.

Hab. Dikoya, 



Oval, dark brown, with a few almost obsolete dirty white 

 patches, assuming a band-like form towards the posterior part 

 of the elytra, or the whole apical third more or less whitish ; 

 rostrum shorter than the prothorax, "and, with the antenna, 

 pitchy; prothorax very transverse, rather flattish above, 

 slightly concave at the sides, closely punctured ; scutellum 

 blackish; elytra moderately convex, striate-punctate, punc- 

 tures linear, not approximate, interstices slightly raised ; body 

 beneath pitchy, with approximate whitish scales; pectoral 

 canal not extending beyond the anterior coxae ; legs pitchy, 

 covered with narrow and some erect scales. 



In this species the canal is shorter than in the preceding or 

 in Acalles generally.

L History of the Name. — The generic term Laganum has 

 had a somewhat chequered history. Introduced into science 



very 



was left unnoticed by Leske in his " Additamenta " to the 

 work of Klein. When first used as a strictly generic appella-
