Genera of the Cossonida. 543 



squamose covering and smaller stature, its surface is more 

 opake and closely sculptured, its rostrum is relatively more 

 elongate and slender, its antennas are more medially in- 

 serted, its scutellum is much less developed, and its legs 

 are setose and proportionately thicker, with the posterior 

 coxae wider apart, and the third tarsal joint more evidently 

 bilobed. 



47. COPTOKHAMPHUS (nov. gen.). The present genus 

 is founded on two species which have been communicated 

 by Mr. Pascoe (obtained, I presume, by Mr. Wallace), 

 one of them from Sarawak in Borneo, and the other from 

 Java. Its affinities are extremely difficult to determine ; 

 nevertheless I believe it to be a member of the Cossonidce, 

 and am inclined to think that the rather inferior position 

 of its transverse and greatly depressed eyes, in conjunction 

 with the fact that its rostrum is conspicuously divided 

 from the forehead, and its surface clothed, or setulose 

 (though in one of the representatives very sparingly so), 

 will tend to place it at no great distance from Himatium 

 an Indian genus (in the collection of Mr. Fry) from 

 Malabar. Yet its rostrum is considerably longer, slenderer, 

 and more curved than that of Himatium, and also very 

 much more separated from the head, the extreme base 

 being far more constricted than what we observe in the 

 groups around even Catolethrus; and its body, instead of 

 being pubescent, is more or Jess scaly and setulose. Cop- 

 torhamphus moreover is remarkable for many peculiarities 

 which are not indicated in any of the types with which I 

 have nevertheless considered it the most natural to asso- 

 ciate it. Thus, for instance, its funiculus (which has the 

 second joint appreciably elongated) is gradually much in- 

 creased in width, causing the club, although large, to be 

 by no means abrupt ; its front coxae are nearly, if not in- 

 deed altogether, contiguous (even more so than in Phlceo- 

 phagus)\ its femora are armed beneath with an acute 

 tooth ; its tibiae are greatly curved, and are furnished to- 

 wards their outer apex (more or less evidently), with a 

 pectinated tuft of setae ; and its prothorax has a large, 

 rounded, sharply-defined, and deep fovea just behind the 

 middle of the disk. This last-mentioned character is so 

 unusual, that I at first thought it must be the result of 

 accident ; but since it is conspicuous in both of the species, 

 I cannot but regard it as a generic eccentricity.
