but nevertheless a little, and gradually, widened both 

 towards its base and apex, and divided from the forehead 

 by a very appreciable line ; in their eyes being exceedingly 

 depressed, transverse, and slightly approximated above ; 

 in their prothorax and metasternum being a good deal 

 lengthened ; in their scutellum being very conspicuous ; 

 in their elytra (which are just perceptibly broader than the 

 prothorax) being deeply sulcated towards the apex where 

 they are separately, and minutely, rounded off; in their 

 antennae and legs (the former of which are inserted con- 

 siderably behind the middle of the rostrum, and have the 

 second funiculus-joint exceedingly abbreviated) being rather 

 short and incrassated ; and in their feet being much thick- 

 ened, with the third articulation conspicuously dilated and 

 bilobed. Their four anterior coxae are about equally wide 

 apart, and the hinder ones are but slightly more remote 

 from each other. 



I am indebted to Mr. Fry, and also to Mr. Janson, for 

 the opportunity of inspecting types of the C. longulus, 

 Bohm., from Mexico ; and several other species are now 

 in my possession (all of them South American) from the 

 exceedingly rich collection of Mr. Fry. My own belief 

 is, that the genus, as properly defined, is essentially an 

 American one ; for although it is true that three or four 

 supposed representatives have been described from the 

 islands of the Pacific, and elsewhere, I think it is never- 

 theless far from unlikely that these latter will be found, on 

 a more critical examination, to pertain to some other 

 group, perhaps to Catolethromorphus, or even to the 

 Pentarthrideous genus Stenotrupis. 



69. STENOTRIBUS (nov. gen.~). The type of this genus 

 is a minute and narrow Brazilian Cossonid (communicated 

 by Mr, Fry as having been received from Bahia), which 

 is without doubt very closely allied to Catoletlirus for 

 one of the smaller members of which it might well at first 

 sight be mistaken. An accurate inspection, however, will 

 show that it cannot in reality be associated with the 

 Catolethri, from which it differs in its antennas being 

 inserted into the middle (instead of considerably behind 

 the middle) of its rostrum; in the latter being more 

 parallel and cylindric (there being scarcely any tendency 

 to either an anterior or a posterior thickening), and even 

 still more conspicuously divided from the remarkably 

 convex forehead ; in its prothorax being extremely elon-
