530 SEERICOENIA. 



parallel than the female of that species, the thorax is more sparsely punctured on the 

 disc, and the elytra are widest at the middle. 



33. Agriotes niexicanus. 



Moderately elongate, rather narrow, convex, slightly shining ; piceous or reddish-brown, the elytra brown ; 

 the antennae brown, with the basal joints testaceous, the abdomen ferruginous at the sides, the legs 

 testaceous ; above and beneath thickly clothed with pale yellowish-cinereous or pale greyish pubescence, 

 the elytra in one specimen with some brownish pubescence on the second and third interstices. Head 

 densely, finely punctate ; antennae extending slightly beyond the hind angles of the prothorax in the male, 

 shorter in the female, joints 2 and 3 equal in length, 3 much shorter than 4. Prothorax about as long as 

 broad, subcylindrical, the sides rounded in front and sinuate behind ; the hind angles long, acute, and 

 divergent, not or obsoletely carinate ; the surface very closely, finely punctate, feebly canaliculate behind; 

 the base feebly incised on either side ; the marginal carina faintly indicated at the base. Elytra three 

 times the length of the prothorax, aud slightly wider than it, a little rounded at the sides, narrowing from 

 the basal third, somewhat pointed behind ; punctate-striate, the interstices flat and rugulosely punctured. 

 Beneath densely and very finely, the prosternum more sparsely, punctate. Hind coxal plates slightly 

 widened inwards. 



Length 7-7f , breadth 2-2| millim. ( J $ .) 



Hab. Mexico (Salle), Jalapa (Edge). 



Four specimens. Much smaller and less elongate than A. incallidus, the thorax 

 more densely and much more finely punctate, and feebly incised at the base, the 

 antennae shorter in the male. From A. binotatus, apart from its less elongate elytra, 

 it may be known by the more finely and less densely punctured thorax. 



34. Agriotes guatemalensis. 



Moderately elongate, narrow, convex, slightly shining ; piceous or brown, the abdomen usually ferruginous at 

 the sides in dark specimens, the basal one or two joints of the antennae and the legs testaceous ; above 

 and beneath somewhat thickly clothed with yellowish-cinereous pubescence, the elytra with darker hairs 

 intermixed. Head very densely punctate ; antennae extending to some distance beyond the hind angles of 

 the prothorax in the male, considerably shorter in the female, joints 2 and 3 equal, 3 much shorter than 4. 

 Prothorax about as long as broad in the male, more transverse in the female, subcylindrical, and with the 

 sides rounded in front and slightly sinuate behind in the male, gradually narrowing from a little before 

 the base in the female ; the hind angles moderately long aud narrow, not or obsoletely carinate, divergent 

 in the male ; the surface densely, finely punctate, deeply canaliculate behind ; the base feebly incised on 

 either side ; the marginal carina obliterated at the middle. Elytra three times the length of the prothorax, 

 and wider than it in the male, a little rounded at the sides, narrowing from about the basal third in the 

 male, from the middle in the female, somewhat pointed behind ; punctate-striate, the interstices flat and 

 rugulosely punctured, rougher at the base. Beneath closely and finely, the prosternum and propleura3 

 more coarsely, punctate. Hind coxal plates a little widened in their inner third. 



Length 6f-7f , breadth 2-2| millim. ( S $ •) 



Hab. Guatemala, Capetillo (Champion). 



Eight specimens. More parallel and more shining than A. opacicollis ; the thorax 

 a little less densely punctured, distinctly narrower than the elytra in the male, and also 

 more transverse in the female ; the elytra less attenuate in both sexes, the pubescence 

 not paler along the suture and at the sides. From the still more nearly allied 

 A. mincius, from Western Mexico, it may be known by the colour of the pubescence
