SCAPTOLENUS. 563 



7. Scaptolenus hirticollis. (Tab. XXV. figg. 6, 6 a, <s .) 



c? . Elongate, moderately broad, attenuate behind, slightly shining ; head, prothorax, and scutellum black, 

 the prothorax obscure castaneous at the sides ; the mandibles castaneous, black at the tip ; the antennse 

 ferrugineo-testaceous, with the three basal joints partly piceous ; the elytra fusco- testaceous ; the body 

 beneath and the femora flavous, the breast and the apex of the abdomen infuscate, the tibiae and tarsi 

 reddish-brown ; the head, prothorax, scutellar region, femora, and breast densely clothed with very long 

 blackish hairs, the long marginal hairs of the elytra also black, the rest of the elytral pubescence short 

 and partaking of the ground-colour. Head sparsely, coarsely, unequally punctate ; eyes large and 

 prominent ; mandibles short, abruptly incurved at the middle, the basal portion very stout ; maxillary 

 palpi with the apical two joints equal in length ; antennas rather short, feebly serrate, joint 3 twice as 

 long as 2, 4 rather more than twice as long as 3, 11 obliquely truncate at the apex. Prothorax short, 

 nearly twice as broad as long, rounded but not dilated at the sides anteriorly, with greatly produced, 

 slender, divergent hind angles ; the surface thickly, finely punctate. Scutellum densely punctured. 

 Elytra very elongate, about three and one-third times the length of the head and prothorax, moderately 

 gibbous at the base, very much wider than the prothorax, and abruptly narrowed from about the basal 

 third ; thickly, rather finely punctate, each with five vague narrow cost® on the disc, the interspaces 

 appparing broadly and shallowly sulcate. 



Length 17, breadth 6| millim. 



Hab. Guatemala, Tecpan in the Los Altos region (Conradt)., 



One specimen. This insect somewhat resembles S. amplipennis, but it has the 

 antennas short and feebly serrate, the long hairs on the head, thorax, and breast are 

 almost black, and the elytra are abruptly narrowed from the basal third, and narrowly, 

 vaguely costate, without trace of striae. In the very elongate, abruptly narrowed elytra 

 it differs from all the allied forms. The only other known species with very long dark 

 villosity on the thorax and breast is 8. guttiventris. 



8. Scaptolenus californicus. (Tab. XXV. figg. 7, 7 «, 6 .) 



<$ . Scaptolenus californicus, Chevr. Ann. Soc. Ent. Fr. 1874, pp. 509 \ 524 2 . 

 Hab. North America, 1 California 2 . — Mexico 1 . 



There are two specimens of this species in M. Rene Oberthur's collection, both 

 labelled " California." As Chevrolat 1 also gives " Mexico " as a locality, and Dr. Horn 

 has expressed his opinion that the insect is really Mexican, I include it in our list. 

 S. californicus is allied to S. guttiventris, from which it differs as follows : — The eyes 

 are much smaller and less prominent, the head thus appearing smaller ; the thorax is 

 relatively narrower and less transverse ; the elytra are much shorter, appearing more 

 narrowed behind, and piceous in colour, with about the basal third indeterminately 

 testaceous ; and the long hairs on the breast are fulvous. The antennse, palpi, and 

 mandibles are similarly formed in the two species. The long hairs on the head and 

 thorax are fuscous in colour. 



9. Scaptolenus sulcipennis. 



$ . Scaptolenus sulcipennis, Chevr. Ann. Soc. Ent. Fr. 1874, pp. 508, 514 \ 



Hab. Mexico {coll. JeJcel 1 ; coll. Oberthur).
