From Rhyncolus, on the other hand, (with which they 

 agree better in their more separated coxae, more elongate 

 bodies, and developed scutellum), the members of Phlceo- 

 phagosoma differ in their very much slenderer and more 

 lengthened rostrum, in their less thickened and more 

 medially implanted antennae, which have a larger and 

 more abrupt club, and in their less prominent eyes. And 

 they are also larger than the Rhyncoli, and have their 

 anterior coxae (particularly however the intermediate pair) 

 rather more remote from each other, though these two 

 characters are less strongly expressed than they were as 

 compared with the corresponding ones of Phlceophagus.* 



The species now before me, which I should regard as 

 pertaining to Phlceophagosoma, are from Japan, New 

 Zealand, the islands of the Malay archipelago, Malacca, 

 Ceylon, Malabar, and southern Africa. The one from 

 the last-mentioned of those regions (which has been com- 

 municated by Mr. Janson) has the name " Phlceophagus 

 ebeninus, Schon." appended to it, but it scarcely seems 

 to me to tally with the published diagnosis of that insect. 



51. PHOLIDOFORUS (Wollaston, Trans. Ent. Soc. Lond. 

 18. 1873). The present genus was proposed in order to 

 receive a very singular Curculionid which appears to be 

 common in the Japanese archipelago, where it was de- 

 tected near Nagasaki, in the island of Kushiu, by Mr. G. 

 Lewis. It is at once remarkable amongst the Cossonida 

 for the thick, cinereous, bristle-like scales with which it is 

 densely studded, a type of clothing with which we are 

 very familiar in other departments of the Rhynchophora, 

 but which is of the rarest occurrence in the Cossonids. 

 In other respects it is conspicuous by its narrowish-fusi- 

 form outline (which is parallel in the middle, but much 

 attenuated both before and behind), for its rather elongated 

 antennas and feet, for its eyes being exceedingly prominent, 

 and for its third tar sal joint being a good deal expanded 

 and bilobed. 



52. COPRODEMA (Wollaston, Trans. Ent. Soc. Lond. 

 20. 1873). Like the last genus, the present one was 



* In the species of PJilceopJiagosoma, which I regard as the more typical 

 ones, the rostrum is of equal breadth throughout ; but in others it is either 

 (as in the P. curvirostris from Japan) a little thickened at the base, or else 

 (as in the P. fusirostris from New Guinea) slightly and gradually so 

 behind the middle.
