Ginera of the Cossonida. 559 



gated, less constricted in front, and perfectly even (there 

 being no traces either of keel or depression) ; in all its 

 coxae being subequallj apart (even the anterior ones being 

 widely separated); and in its feet being much less in- 

 crassated, and with their third joint small and simple. 

 Its elytra too are more decidedly parallel (or less fusiform) 

 than in Catolethrus ; its body is less depressed ; its colour 

 is nearly black ; and its eyes are so extremely sunken as 

 to be with difficulty detected. 



[70. PROECES (Schonherr, Gen. et Spec. Cure. iv. 

 1080. 1838). The present genus is one of six which 

 I have not been able to inspect; but the two species to 

 contain which it was established by Schonherr, and which 

 are apparently peculiar to Madagascar, are stated by 

 Lacordaire to be very similar at first sight to the smaller 

 members of Catolethrus, and quite as narrow. Their 

 rostrum however is said to be slenderer and more cylin- 

 drical; their antennae are shorter and less thickened, 

 with the second funiculus-joint longer, and the club larger 

 and more abrupt ; and their legs are thinner, with the third 

 articulation of the feet simple and not at all wider tha^i 

 those which precede it.] 



71. PHACEGASTER (nov. gen.). Although it does not 

 tally precisely with the diagnosis, I have little doubt that 

 the insect for which the present genus is proposed is the 

 Catolethrus nasalis of Boheman, from Brazil. At any rate 

 several examples are now before me (collected by Mr. Fry 

 near Rio Janeiro, and in the province of S ta Catharina) 

 which I feel satisfied are congeneric, and I believe also 

 conspecific, with the nasalis ; but it is nevertheless quite 

 evident that they cannot be associated with the Catolethri. 

 Not to mention their much larger size, they differ essen-* 

 tially from the latter in the form of their rostrum which 

 is very much broader, somewhat depressed above, and 

 gradually (though not very considerably) widened from its 

 base to its apex ; and the antennas are implanted into it 

 nearer to the middle point, In other respects, Phaeegaster- 

 is remarkable for a great peculiarity in its first and second 

 abdominal segments each of which are furnished with 

 two rounded, ocelli-like spaces, filled up with coarse 

 granules, The two on the basal segment are rather larger 

 and more widely separated from each other than those on 

 the second one, and are placed before the middle ; whereas
