SCAPTOLENUS. 561 



the interstices narrowly, vaguely costate, and thickly, finely punctate. Anterior tibia? with the median 

 dilatation obtuse, the apical tooth long. 

 Length 16|, breadth 6 millim. 



Hab. Mexico, Parras in Coahuila (Br. Palmer). 



One mutilated specimen. Belongs to Chevrolat's second division of the genus, 

 differing from S. vagans in the stouter palpi, with the penultimate joint thicker than 

 the apical one, the more strongly serrate antennae, the larger eyes, the broader thorax, 

 with less produced hind angles, and the obtuse median tooth of the anterior tibiae. 

 The less elongate, more strongly serrate antennae, the feebly sulcate elytra, and the 

 form of the maxillary palpi separate it from S. acutangulus. From S. fulvus and 

 S. lecontei, Cbevr., it may be known by its less robust, narrower shape, longer elytra, 

 sparser villosity, the form of the palpi, &c.

 2, 2 a, b (?) \ 



Hab. Mexico (coll. Oberthihr, ex Chevrolat), La Parada in Oaxaca (Boucard, Salle 1 ). 



The types ( 6 and 2 ) of this species are contained in the Salle collection, and 

 there is also a male of it in M. Rene Oberthur's collection. In S. vagans ( S ) the 

 antennal joints 4-10 are somewhat acutely produced at their inner apical angle ; the 

 thorax is very much narrower than the elytra, and not dilated at the sides in front ; 

 and the elytra are broad and gibbous at the base, rapidly narrowing posteriorly, and 

 moderately elongate. The head, thorax, scutellar region, and breast are thickly clothed 

 with very long fulvous hairs. The apical two joints of the maxillary palpi are equal 

 in length. An antenna of the male is figured. 



4. Scaptolenus acutangulus. (Tab. XXV. figg. 3, 3 a, <$ .) 



£ . Elongate, broad, much narrowed behind, feebly shining ; head, prothorax, and scutellum black, the man- 

 dibles castaneous, black at the tip, the antennae infuscate, the elytra and the body beneath piceous, the 

 apical margins of the ventral segments testaceous, the femora flavous, the tibiae and tarsi obscure reddish- 

 brown ; the head, prothorax, scutellar region, and femora thickly clothed with long pale fulvous hairs, 

 the rest of the elytra sparsely pubescent, the margins fimbriate, the ventral segments with long scattered 

 fulvous hairs. Head very sparsely, coarsely, unequally punctate, the eyes large and prominent ; mandibles 

 short, abruptly incurved at the middle, the basal portion stout ; maxillary palpi long and rather slender, 

 the apical two joints equal in length ; antennae very elongate, joint 3 twice as long as 2, and 4 nearly three 

 times as long as 3, the joints from the fourth abruptly and angularly dilated at the inner apical angle, 

 11 constricted at about one-third from the apex, with the apical portion narrow. Prothorax about three- 

 fifths broader than long, rounded at the sides anteriorly, slightly constricted behind, with very long, 

 slender, divergent hind angles ; the surface thickly, rather finely punctate, depressed along the middle. 

 Scutellum densely punctured. Elytra three times the length of the head and prothorax, and much wider 

 than the latter, rapidly narrowing posteriorly, gibbous at the base and flattened on the disc ; deeply 

 sulcate, with the interstices convex, and rather sparsely, finely punctate. 



Length 15, breadth 5f millim.
