SCAPTOLENUS. 573 



(including the type) of S. chevrolati are available for examination. Some of the examples 

 of S. femoralis have a short smooth raised line on the median basal lobe of the thorax. 

 The elytral costse are sometimes quite obsolete. 



We figure one of Chevrolat's types (var. b) from Mexico ; also a variety from Cache, 

 Costa Rica. 



28. Scaptolenus obscuriceps. (Tab. XXV. fig. 27, s .) 



$ . Scaptolenus obscuriceps, Chevr. Ann. Soc. Ent. Fr. 1894, pp. 509, 520 \ 

 Hab. Mexico, Panistlahuaca in Oaxaca [Salle 1 ). 



Unique in the Salle collection. The type is somewhat immature, and has the apical 

 four joints of the antennae broken off; it differs from S. femoralis in its paler colour, 

 and in having the elytra more coarsely punctured and the fulvous hairs on the thorax 

 longer. The shorter and less parallel elytra separate it from S. chevrolati. 



29. ScaptolenUS longicornis. (Tab. XXV. fig. 26, 6 , antenna.) 



<$ . Elongate, rather narrow, slightly attenuate behind, shining ; pitchy-brown, the head black, the body 

 beneath and the femora luteous, the antennae ferrugineo-testaceous, with the three basal joints piceous, 

 the mandibles castaneous, black at the tip, the tibiae and tarsi piceous ; the head, prothorax, and scutellar 

 region clothed with rather short, decumbent fulvous hairs, the breast with longer similarly-coloured 

 hairs, the rest of the elytra finely pubescent, the margins fimbriate. Head sparsely, somewhat coarsely 

 punctate, the eyes large and prominent ; mandibles short, abruptly curved i awards at the middle ; 

 maxillary palpi with the apical two joints equal in leugth ; antennae long and slender, joint 3 a little 

 longer than 2, 4-10 elongate and subparallel, 4 three times as long as 3, 11 feebly constricted before the 

 apex. Prothorax about three-fifths broader than long, rounded but not dilated at the sides anteriorly, 

 with very long, slender, divergent hind angles ; the surface thickly, rugulosely punctate. Scutellum 

 closely punctured. Elytra elongate, about two and three-fourths longer than the head and prothorax, 

 and a little wider than the latter, feebly gibbous at the base and flattened on the disc, narrowing 

 posteriorly; sparsely, moderately finely, subseriately punctate, and towards the suture narrowly, 

 obsoletely costate, without trace of striae. 



Length 17 §, breadth 5f millim. 



Hab. Guatemala, Ceiro Zunil {Champion). 



One broken specimen from the Pacific slope. Very near S. fem,oralis, but with 

 considerably longer antennae, longer and more slender hind angles to the thorax, and 

 (apparently) flatter elytra. The elytra are much more elongate than in S. teapensis, 

 and quite sparsely punctured.
