614 SEBB1C0RNIA. 



12. Scirtes longicornis. 



Elliptic, moderately convex, shining ; nigro-piceous, the head and prothorax black, the margins of the latter 

 rufescent, the antenna? piceous or obscure testaceous, with the basal joints testaceous, the legs testaceous, 

 with the femora partly piceous, the body beneath piceous or brownish ; sparsely clothed with very fine 

 brownish pubescence. Head, prothorax, and scutellum somewhat thickly, minutely punctate ; head very 

 broad, the eyes large and rather prominent; antennas nearly as long as the body, not very slender, 

 joint 3 very minute, scarcely more than half the length of 2, 4-11 very elongate, flattened, and equal in 

 length ; prothorax convex, short, narrowing from the base, sharply margined at the sides ; elytra thickly, 

 finely punctate, the punctuation coarser than that of the prothorax, narrowly margined at the sides. 



Length 21-3, breadth lf-lf millim. 



Hab. Panama, Bugaba, Volcan de Chiriqui {Champion). 



Seven examples. This small species may be at once identified by the usually elongate 

 antenna?, these organs being nearly as long as the body : the third joint is very minute, 

 and the following ones very long and flattened. The specimens show no variation in 

 colour, except that the antennae and under surface are paler in some of them. 



13. Scirtes collaris. 



Elliptic or rotundate-elliptic, rather convex, shining ; the head varying in colour from black to testaceous, the 

 prothorax reddish-yellow or flavo-testaceous, in one specimen with a transverse black mark on the disc 

 (perhaps due to discoloration), the scutellum piceous or black, the elytra black or pitchy-black, the body 

 beneath piceous, the antennae black or piceous, with the basal three or four joints testaceous, the legs 

 varying in colour from piceous to testaceous ; the elytra clothed with fine brownish pubescence, the head 

 and prothorax with pallid pubescence. Head, prothorax, and scutellum thickly, very minutely punctate ; 

 antennas long and rather stout, joint 3 extremely small, much shorter than 2, 4-11 elongate, gradually 

 decreasing in length ; prothorax very short and convex, narrowing from the base, finely margined at the 

 sides ; elytra thickly, finely punctate, the punctuation coarser than that of the prothorax, narrowly 

 margined at the sides. 



Var. The elytra with a common reddish-yellow sutural stripe, extending from a little below the scutellum to 

 the apex and narrowing posteriorly. 



Length 2|-2f , breadth 1£-1| millim. 



Hab. Guatemala, Cubilguitz, Chiacam, and San Geronimo in Vera Paz, San Isidro 

 (Champion); Panama, Volcan de Chiriqui (Champion). 



Six specimens of the typical form — three from Vera Paz and three from Chiriqui— * 

 and two of the variety, the latter being from San Isidro. The variety closely resembles 

 the North-American S. orbiculatus (Fabr.), but differs from it in the much longer and 

 darker antenna? ; the elytra are punctured exactly as in that species. In the typical 

 examples there is no trace of a common central spot on the elytra. From S. ater, which 

 also has an extremely small third antennal joint, it may be easily known by its smaller 

 size and less convex shape, and the stouter and blacker antenna?, as well as by the 

 colour of the thorax. 



/ 14. Scirtes suborbiculatus. (Tab. XXVII. fig. 5, var.) 



Eotundate-elliptic, rather convex, shining, finely pubescent; the head varying in colour from black to 

 testaceous ; the prothorax yellow or reddish-yellow, usually with four black or piceous spots on the 

 disc, these sometimes united and forming a broad cruciform patch, and sometimes indistinct or entirely
