ON A KEMAKKABLE NEW OENUS OF CUCUJIBM FROM BRAZIL. 



BT A. SIDNEY OLLTFF. 



AciPHUS, gen. nov. 

 Body elongate, much depressed. Head moderately large, broadly transverse. 

 Eyes small, elongate, situated just behind the base of the antennse, very finely 

 facetted and not prominent. Antennse, ll-jointed ; the basal joint very long, 

 slender, widening out into a flattened club at the extremity, the second joint very 

 short, but distinctly longer than broad : the third about tvrice as long as the second ; 

 the fourth to tenth nearly equal in length ; the apical slightly longer than the pre- 

 ceding. Mandibles prominent, incurved, moderately stout and not grooved. 

 Proohorax considerably longer than the head ; the sides oblique, "with a feeble 

 emargination on each side just behind the middle. Scutellum rather long, the sides 

 nearly parallel, pointed behind. Elytra only extending to just before the base of the 

 second abdominal segment; humeral angles somewhat prominent ; outer apical angles | 

 rounded. Abdomen with the terminal segment rounded behind. Legs rather short 

 femora very stout ; the four anterior tarsi 5-jointed, the first joint slightly elongate,! 

 the second and third somewhat shorter, the fourth small, the fifth about as long asj 

 the three basal joints together ; posterior tarsi 4-jointed, the basal joint as long as; 

 the two succeeding ones together ; claws with a slight enlargement near the base. 



The genus characterized above is allied to Diagrypnodes, Waterh. 

 (Trans. Enfc. Soc. Lond., 1876, p. 13), but differs in having the head 

 transverse, the mandibles simple instead of grooved, and in the form 

 of the scutellum. The basal joint of the antennse is longer, and the 

 eyes are situated nearer the bases of those organs. 



ACIPHUS SINGULAEIS, Sp. n. 



Elongate, very strongly depressed, pale reddish-testaceous, shining ; the disc ol 

 the head except near the base, mandibles, apex of each elytron and the knees pitchy- 

 black. Head much broader than long, narrowed in front of the eyes, extremelj) Sifl 

 finely punctured ; the sides nearly parallel ; the posterior margin with a slight (p, 

 sinuation on each side of the middle. Antennse slender, filiform, reaching beyonci »,' 

 the apex of the elytra. Prothorax much longer than the head, considerably broadoj ' 

 in front than behind, somewhat concave, with scarcely any trace of punctuation j ^ 

 anterior angles rounded ; the sides oblique, with a feeble emargination just behint 

 the middle ; posterior angles obtuse ; the median line indistinct. Scutellum ex 

 tremely finely punctured. Elytra at the base slightly narrower than the hei 

 widening posteriorly, extremely finely and very sparingly punctured ; the sidel 

 arcuately rounded behind : each elytron with a very feebly impressed line extendi: 

 from the shoulder to just before the inner apical angle. Abdomen pale testaceoiis 

 all the segments except the first with a moderately large dusky spot on each side Oj 

 the middle. Length, 6 mm. ; greatest width, 1^ mm. 



Eio Janeiro (Squire). Type in the collection of Mr. E. Wl 

 Jan son. 



This curious species is allied to Diagrypnodes TVakeJlel dii, Wsiterh 

 (I. c), described from New Zealand.
