SCAPTOLENTTS. 569 



The type of this species is contained in the Salle collection, and we also possess an 

 example of it from Jalapa. Chevrolat's second specimen (now in the collection of 

 M. Rene Oberthiir) is probably referable to S. femoralis. In this insect the hairs on 

 the thorax are rather short and decumbent, and brownish in colour; the outer joints 

 of the antennae are very slightly dilated at the apex; the mandibles are short; the 

 apical two joints of the maxillary palpi are equal in length; the thorax is not very- 

 much narrower than the elytra ; and the elytra are narrowed behind, deeply sulcate, 

 with the interstices convex, and rather sparsely punctured. 



21. Scaptolenus subapicalis. 



<J. Scaptolenus subapicalis, Chevr. Ann. Soc. Ent. Fr. 1874, pp. 509, 519 \ 

 Hab. Mexico (coll. Mniszech 1 ). 



The type of this species cannot now be identified with certainty ; but in the Mniszech 

 collection (now in the possession of M. Rene Oberthiir) there is a Mexican specimen 

 agreeing fairly well with the description. There are also two others from Mexico in 

 M. Oberthiir's collection, one from that of Chevrolat (incorrectly labelled S. villosus), 

 that probably belong to it. These three specimens have the head black, the thorax 

 more or less infuscate, the elytra fusco-testaceous (blackish at the apex in one example), 

 and the under surface and femora luteous. The yellowish-cinereous pilosity of the 

 thorax is rather short and decumbent, that of the breast being much longer and 

 denser. The thorax is a little dilated at the sides anteriorly, not twice as broad as long, 

 with long, slender hind angles. The elytra are elongate, a little wider than the thorax, 

 distinctly narrowed posteriorly, shallowly sulcate, with the interstices narrowly, vaguely 

 costate, and somewhat thickly, finely punctate. The mandibles are short ; the apical 

 two joints of the maxillary palpi are equal in length ; and the fourth and following 

 antennal joints are very little widened outwards. 



Compared with S. femoralis, these examples are less parallel, and they have the 

 thorax less transverse, with more slender hind angles and rather longer pubescence.

Guerin's original type of Cebrio chevrolati is contained in M. Rene Oberthiir's 

 collection. There are also two specimens of it in the Salle collection, named as male 

 and female of the same species, the female being the one figured by Chevrolat 3 as 

 S femoralis. In this species the thorax and elytra are fulvous-brown in colour : the
