This insect seems to be fairly common in Brazil, and is 

 easily recognisable amongst its allies by the mucronate 

 apices of the elytra, the catenulate, posteriorly tuberculate 

 alternate interstices, 1, 3, 5, 7 and 9, and the simple an- 

 tennae and legs in the two sexes. The terminal joint of 

 the antennae about equals 8-10 united in 2, and is slightly 

 longer in (^. The colour varies from ferruginous or rufo- 

 castaneous to piceous; the two examples with black 

 elytra, from Constancia and Espirito Santo, may belong to 

 a different species. The elytra in S. agroides are said to 

 have a " bluish- violet reflection which ought to be more 

 distinct in the living insect," a character of no importance 

 in this genus. The imperfectly described S. intemtpte- 

 costata, Pic,^ from French Guiana, seems to be an allied 

 form. 



9. Statira longiceps, n. sp. (Plate XII, fig. 6.) 



Very elongate, shining; fusco -testaceous, the head and antennae 

 rufescent, the latter with joints 1-3 and 11 darker, the eyes, palpi, 

 and labrum black or piceous, the prothorax (except at the base) 

 also slightly infuscate; elytra with a few long, bristly hairs. Head 

 oblong, narrow, almost smooth, longitudinally grooved between the 

 eyes, the latter large, somewhat depressed, well separated ; anteimae 

 long, rather slender, joint 11 as long as 8-10 vmited. Prothorax 

 wider than the head, much longer than broad, gradually narrowed 

 from the middle forward, and constricted before the base, the 



* A large chitinous tube from which the penis-sheath is extruded : 

 it is usually withdrawn into the body, and not visible without 

 dissection.
