foveate between the eyes ; the rostrum cylindrical or subcylindrical, not in the least 

 dilated at the tip ; the eyes rather prominent in the typical Stenomimi, smaller and 

 more depressed in Allomimus, and placed, as it were, at the sides of the rostrum 

 immediately in front of the globose portion of the head; the antennal club abrupt, the 

 funiculus 7-jointed ; the prothorax suboval or subcorneal ; the scutellum small, but 

 conspicuous ; the elytra deeply punctate-striate or punctato-sulcate, the sutural stria 

 often deeper and broader than the others, the outer interstices narrow and the inner 

 ones not wider than the strise ; the anterior coxse (except in S. quichensis) separated by 

 at least their own width ; the tibiae more or less acute or mucronate at the inner apical 

 angle, the anterior pair sinuate within ; and the tarsal claws small. The ventral 

 excavation of the male is usually large, and often extends forward on to the meta- 



sternum. S. vercepacis, S. rufipes, &c, approach Allomimus ; S. wollastoni, S. guate- 

 malensis, &c, are related to S. fryi ; S. rugirostris has a finely pubescent body, &c, 

 and it may have to be removed eventually and placed near Carjphonotus. Mr. Barber 

 has kindly forwarded examples of three of the N.- American forms for comparison, and 

 I am therefore enabled to include them in the subjoined Table * : 



a. Body glabrous or subglabrous ; prothorax distinctly narrower than the 



■ 





elytra. 



a\ Hostrum long or moderately long, comparatively slender, cylindrical 



(shorter in S. dirutus). [Stenomimus, WolL] 

 a 2 . Antennse inserted just behind the middle; rostrum about three- 



fourths the length of the prothorax; elytra coarsely punctato- 

 sulcate : body nigro-piceous, depressed, elongate filirostris, sp. n. 



Z> 2 . Antennae inserted at or just beyond the middle; eyes rather 



■ 



prominent. 

 a 3 . Prothorax abruptly constricted and tubulate in front; antennal 



club rather elongate ; elytra much broader than the prothorax, 

 deeply punctato-sulcate ; anterior tibiae (<J) sharply mucronate 

 at the apex within : body black armatus, sp. n.

6\ Prothorax moderately or feebly constricted m front, oval or sub- 

 conical. 

 a 4 . Disc with indications of an irregular double series of coarser 



punctures towards the base, and also more or less depressed, 



down the middle. 

 a 5 . Elytra coarsely punctato-sulcate 



dimtus, sp. n. 



b\ Elytra more finely punctato-sulcate wollastoni, sp. n. ;

guatemalensis, sp. n. ; \_pallidus, Boh.].

Bhyncolus corticalis, Boh., said by Schwarz to be an Allomimus allied to A. dubiv.s, is unknown to me. 







8. pallidus (Boh.) was referred by Schonherr to Phlceojphagus.
