SCAPTOLENUS. 565 



tip ; antennae short and slender, tapering outwards, joint 3 about twice as long as 2, and 4 twice as long 

 as 3, the joints from the fourth distinctly serrate, 11 abruptly constricted beyond the middle, and with 

 the apical portion slender. Prothorax largely developed, about three-fifths broader than long, rounded 

 and dilated at the sides anteriorly ; the hind angles acute and divergent, comparatively short ; the surface 

 thickly, rather finely punctate. Scutellum densely punctured. Elytra oval, nearly three times as long 

 as the head and prothorax, and not much wider than the latter at the base, gibbous in front and flattened 

 on the disc ; sulcate, with the interstices feebly, narrowly costate, and thickly rather finely punctate. 

 Length 17, breadth 6| millim. 



Hab. Mexico, Ventanas in Durango 2000 feet (Forrer). 



One example. Belongs to Chevrolat's third division of the genus, near S. sulcipennis. 

 The more oval elytra, the shorter and more serrate antennae, with strongly constricted 

 apical joint, and the longer hairs on the thorax, separate it from S. guerini, which also 

 has longer hind angles to the thorax.

 Hab. Mexico (Salle, ex coll. Sturm 1 ). 



Described from two specimens, one of which, the type, is in the Salle collection. 

 S. villosus somewhat resembles S. fulvus ; but it has the thorax relatively broader and 

 considerably dilated at the sides anteriorly, the elytra less elongate, the mandibles 

 shorter, the maxillary palpi infuscate and much shorter and stouter, the eyes less 

 prominent, and the antennas very feebly serrate. The hairs on the head, thorax, 

 scutellar region, femora, and breast are very long and fulvous in colour. The apical 

 joint of the maxillary palpi is about as long as the preceding. The specimens placed 

 under the name S. villosus in the de Bonvouloir collection (now in the possession of 

 M. Rene Oberthur) belong to other species. 



The type is figured. 



13. Scaptolenus mouffleti. (Tab. xxv. figg. 11, 11 a, <$ .) 



$ . Scaptolenus mouffleti, Chevr. Ann. Soc. Ent. Fr. 1874, pp. 509, 523 l . 

 Hab. Mexico, Vera Cruz (Moufflet, in coll. Salle 1 ). 



Unique in the Salle collection. This species resembles S. vagans in shape, but the 

 antennal joints are stouter and not dilated at the apex. The thorax is much larger, 

 and dilated at the sides anteriorly. The elytra are short, greatly narrowed behind, and 

 dehiscent from about the basal third. The mandibles are short, acute at the tip. The 

 apical two joints of the maxillary palpi are equal in length. The hairs on the head, 

 thorax, and breast are very long and fulvo-cinereous in colour.
