CYPHON. 619 



cate at the tip, the body beneath reddish-brown. Head moderately broad, thickly, very minutely 

 punctate, the eyes rounded and rather small ; antennae long and slender, more than half the length of 

 the body, joint 3 small, shorter than 2, the other joints elongate. Prothorax very short and broad, 

 moderately convex, the sides gradually converging forwards, distinctly explanate, and acutely margined ; 

 the surface punctured like that of the head. Elytra rather elongate, somewhat parallel in their basal 

 half, flattened on the disc, the humeri rounded, the apices obliquely truncate ; closely, very finely punc- 

 tate, the punctuation a little coarser than that of the prothorax, with three faint raised lines — two on 

 the disc, oblique, and one at the sides ; each elytron with a very deep, large, oblique, pyriform impression 

 on the inner part of the disc immediately before the apex, the impressions extending to the suture, with 

 their narrow ends forwards. 



S • Oval, rather convex ; the elytra without impressions near the apex, a little flattened on the disc towards 

 the base, the raised lines on the disc very faint or obliterated, the apices rounded. 



Length 2^-24, breadth lf-l| millim. 



Hab. Guatemala, San Isidro {Champion) ; Panama, Caldera, David and Tole in 

 Chiriqui [Champion). 



Eleven females and four males, all but one, a male, from Chiriqui. 



The males are very dissimilar from the females, but, as they were obtained in 

 company at David, there can be no doubt that they belong to one species. The 

 genitalia of both sexes have been examined. The deep ante-apical foveas of the elytra 

 in the female extend obliquely forwards, and are pyriform in shape, their narrow ends 

 meeting at the suture. The margins of the thorax are explanate. The sculpture of 

 the apices of the elytra is very like that of the males of various species of Malachius. 

 The localities for this insect are all on the Pacific slope, and in the " tierra caliente." 



2. Cyphon quadrifoveolatus. (Tab. XXVII. fig. 8, elytron, $ .) 



2 . Elongate, narrow, subparallel, depressed, shining, finely pubescent ; piceous, the legs and antennae 

 testaceous, the latter slightly infuscate at the tip. Head moderately wide, closely, minutely punctate, 

 the eyes small and rounded ; antennae about half the length of the body, joint 3 very small, much shorter 

 than 2, 4 elongate, longer than 5, the others longer than broad. Prothorax very short and broad, 

 moderately convex, the sides gradually converging forwards and sharply margined ; the surface closely, 

 distinctly punctate. Elytra rather elongate, subparallel in their basal half, flattened on the disc, the 

 margins not visible from above, the humeri rounded, the apices obliquely truncate, the disc with indi- 

 cations of one or two raised lines ; the surface closely, very finely punctate, the punctuation a little 

 coarser than that of the prothorax ; each elytron with a very deep, large, oblique, oval impression at the 

 base within, and a very deep, large, round fovea on the inner part of the disc immediately before the 

 apex, the foveae extending to the suture. 

 Length 2-2%, breadth 1-1 1 millim. 



Hab. Mexico, Cuernavaca in M orelos (H. H. Smith) ; Guatemala, San Geronimo 

 (Champion). 



Two female examples of this peculiar insect have been obtained. It approaches 

 C. impressus, Lee, from Florida. The following is an allied form. 



3. Cyphon parallelus. (Tab. XXVII. fig. 9, elytron, 2 •) 



2 . Elongate, narrow, subparallel, depressed, shining, finely pubescent; piceo-testaceous, the legs and antennae 

 testaceous, the latter infuscate at the tip. Head moderately wide, closely, minutely punctate, the eyes 

 rounded and very small ; antennae moderately slender, about half the length of the body, joint 3 very
