Protliovax lateribus ad basin mediocriter inflexis, antice hand 

 inflexis, lineis marginalibus tantuin ad angulos anteriores conjunctis,

This curious insect may, I believe, be considered as an aberrant 

 member of the Quediina. It has, perhaps, more the aspect of a 

 Cafius than of any other known genus, but it diiifers totally there- 

 from by the structure of the side-piece of the prothorax. I have 

 pointed out elsewhere that the essential character by which the 

 Quediina are distmguished is that the prosternum is not placed 

 quite at the front of the thorax, but leaves the anterior angles free 

 and projecting. This is the case in Cafioquedus, though to a slighter 

 extent than in the other genera of the group. Looking on the genus 

 as a member of the Quediina, the very peculiar form of the pro- 

 thoracic side-piece, which in front is scarcely at all inflexed, is 

 diagnostic : both marginal lines are quite distinct till the front 

 angles are reached, and exactly at this point they are joined. The 

 other characters throw but little light on the aftinities, though the 

 general structure is apparently that of Philonthus. The antenna; 

 are similar to those of the larger Philonthi ; the lahrum very short, 

 quite divided ; the mandibles long and slender, dentate in the 

 middle. The ligula is apparently bilobed, but of this I am not 

 quite sure. The labial palpi are rather slender, with the terminal 

 joint quite slender, subhnear, a good deal longer than the penulti- 

 mate joint. The penultimate joint of the maxillary palpi is broader 

 at the apex than at the base ; the terminal joint of very slender oval 

 form, slightly shorter than the penultimate. The middle coxa- are 

 slightly separated. 



1848. C. gularis, «-s- (Sharp; Trans. Boy. Dub. Soc, 1886, 

 p. 377.) Elunijatus, subcylindricus, niger, parce albido-pruinosus, 

 capite subtus gula sanguinea ; prothorace transversim fortiter con-

Long., lonnn. 



Antennae black, moderately slender; third joint longer than 

 second ; joints 4-10 each minutely red at the base, the penultimate 

 three or four joints each slender at the base ; the penultimate 

 not so long as its greatest width ; terminal joint short, strongly 

 obliquely sinuate. Head rather elongate, eyes rather large, sides 

 for some distance behind them almost straight, then distinctlj- nar- 

 rowed to the broad neck ; along the inner margin of the eyes is a 

 series of coarse punctures, and between this series and the neck are 

 some other coarse punctures, marking off a rather large space about 

 the hind angles on each side, which is finely punctate, and bears a 

 scanty white pubescence. Thorax rather long, black, shining, and
