thorax, which is marked with a sharply defined black cross. The elytra usually have 

 the suture and a submarginal stripe clothed with paler pubescence. 



31. Agriotes incallidus. 



Agriotes incallidus, Cand. in litt. 



Elongate, rather broad, moderately convex, shining; piceous, pitchy-brown, or reddish-brown, the elytra 

 paler than the prothorax in dark specimens, the metasternum and abdomen ferruginous at the sides, the 

 antennas ferrugineo-testaceous, the legs testaceous ; above somewhat thickly, beneath densely, clothed 

 with pale yellowish-cinereoas . pubescence. Head closely punctured ; antennae slender, extending to a 

 little beyond the hind angles of the prothorax in the male, shorter in the female, joints 2 and 3 subequal 

 in length, 3 slightly shorter than 4. Prothorax a little longer than broad, subcylindrical, the sides 

 rounded in front and feebly sinuate behind ; the hind angles long and acute, moderately divergent, not 

 carinate ; the surface thickly, somewhat coarsely punctate, the punctuation becoming sparser behind, 

 deeply canaliculate from the middle to the base ; the base sharply incised on either side ; the marginal 

 carina obliterated for some distance before the middle. Elytra three times the length of the prothorax, 

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

 both sexes, somewhat pointed behind, the apices acute ; finely punctate-striate, the interstices flat and 

 rugulosely punctured. Beneath, the propleurse included, densely, finely punctate, the prosternum with 

 coarser and more scattered punctures. Hind coxal plates slightly widened in their inner third. 



Length 91-10, breadth 2f-3 millim. ( <$ $ .) 



Hah. Mexico (coll. Janson, ex Candeze), Cordova (Salle), Jalapa (Hoge) ; Guatemala, 

 Coban in Vera Paz (Conradt). 



Numerous examples from Eastern Mexico, two only from Guatemala ; one of the 

 former is labelled with the name here adopted. This insect resembles A. longipennis ; 

 but it has the elytra relatively less elongate, and the thorax broader, with deep basal 

 incisures. The last-mentioned character will serve to separate it from A. fulvescens, 

 A. monticola, &c. From A. vaccinus it may be known by the more parallel, coarsely 

 punctured, very deeply canaliculate thorax. 



32. Agriotes monticola. 



$ . Elongate, narrow, convex, subparallel, slightly shining; reddish-brown, the disc of the prothorax indeter- 

 minately iufuscate in the middle ; above and beneath somewhat thickly clothed with yellowish-cinereous 

 pubescence, the pubescence on the disc of the prothorax radiating from the centre. Head densely 

 punctured ; antennas not extending beyond the hind angles of the prothorax, joint 3 longer than 2, and 

 very little shorter than 4. Prothorax subcylindrical, a little longer than broad, the sides rounded in front 

 and feebly sinuate behind ; the hind angles moderately long and slightly divergent, not carinate ; the 

 surfaco closely and rather coarsely punctate, the punctuation becoming sparser on the disc, canaliculate 

 behind, and with a narrow smooth space along the middle ; the base feebly incised on either side ; the 

 marginal carina distinct at the base and apex only. Elytra three and one-third times the length of the 

 prothorax, gradually widening to the middle and narrowing thence to the apex, the apices narrow; 

 punctate-striate, the interstices feebly convex and rugulosely punctate. Beneath closely and finely, the 

 prosternum and propleurse more sparsely, punctate. Hind coxal plates slightly widened in their 

 inner third. 

 Length 9|, breadth 2f millim. 



Hab. Guatemala, Volcan de Agua between 8500 and 10,500 feet (Champion). 



One example. This insect is allied to A. incallidus ; but it is narrower and more
