AGEIOTES. 517 



specimens of the var. |3 from Coban the marks on the thorax are united and form a 

 subcruciform patch. We figure three specimens : the type of A. pulcherrimus from 

 the Salle collection ; one of the types of the var. ligatus from the Candeze collection ; 

 and an example of the var. /3 from Coban. 



6. Agriotes fulvescens. 



Agriotes fulvescens, Cand. Monogr. Elat. iv. p. 365 l . 

 Agriotes cervinus, Deyr. in coll. Salle. 



Hab. Mexico {coll. Janson x ), Juquila {Salle). 



This insect is compared by Candeze with A. pexus, instead of with A. pulcherrimus, 

 of which it is probably a variety with the fusco-pubescent spots on the thorax oblite- 

 rated. In several of the specimens there is a fusco-pubescent stripe on the disc of each 

 elytron, as wide as in some of the varieties of A. pulcherrimus. The thorax usually 

 has a large black patch on the disc before the middle. 



7. Agriotes castaneipennis. (Tab. XXII. fig. 24.) 



Elongate, rather convex, shining ; piceous, the elytra castaneous, the mouth-parts (the tips of the mandibles 

 excepted) ferruginous, the basal joints of the antennae and the legs testaceous ; thickly pubescent, the 

 pubescence fulvous above, paler at the sides of the prothorax behind, and pale greyish beneath, the hairs 

 on the disc of the prothorax transversely combed inwards. Head densely, finely punctate ; antennae 

 scarcely reaching the hind angles of the prothorax, joints 2 and 3 equal, 3 much shorter than 4. Pro- 

 thorax much longer than broad, subcylindrical, the sides a little rounded and converging anteriorly and 

 feebly sinuate behind ; the hind angles rather stout, moderately long and slightly divergent, very finely 

 carinate ; the surface densely, finely punctate, deeply canaliculate behind, and with a narrow smooth 

 space along the middle ; the base with a short incisure on either side ; the marginal carina entire. 

 Elytra two and two-thirds the length of the prothorax, and equalling it in width, a little rounded at the 

 sides, gradually narrowing from about the basal third, the apices rather narrow and conjointly rounded; 

 very finely punctate-striate, the punctures somewhat widely separated and very little coarser than those 

 of the interstices, the latter flat and thickly, minutely punctured. Heneath densely, fiaely punctate, the 

 prosternum more sparsely punctured. Hind coxal plates a little widened in their inner third. 



Length 111, breadth 2f millim. 



Hah. Guatemala, Zapote (Champion). 



One specimen. Less elongate and more parallel than A. pexus, the elytra much 

 shorter and narrower, and very finely punctate-striate, the hind angles of the thorax 

 feebly divergent, &c. From A. fulvescens it may be known by its less densely punc- 

 tured and longer thorax, the hind angles of which are shorter, stouter, less acute, and 

 scarcely divergent, and the median channel deeper, the narrower, very finely striate 

 elvtra, the more shining surface, &c. 



8. Agriotes pexus. (Tab. xxii. fig. 25.) 



Agriotes pexus, Cand. Monogr. Elat. iv. p. 365 '. 



Hab. Mexico, Jacale (Salle 1 ); Guatemala, Purula in Vera Paz (Champion). 



I have seen seven specimens of this species — three from Mexico, including the
