142 AMERICAN COLEOPTERA 



Male. — Front tarsi 2-jointed ; hind coxse with a moderately long acute spine on 

 the inner side, ventral surface not ascending at apex. 



Female. — Tarsi normal; hind coxse without spine; ventral surface ascending 

 at apex. 



Hab. — Washington, D. C. — "In drugs;" "in dust from feed 

 store;" and "among Alaskan Lepidoptera." 



This species was described by Wollaston in 1871 from specimens 

 taken on the interior walls of a bouse at Funcbal, Madiera. Since 

 then it has been recorded from the Canaries, Algeria, Cape of Good 

 Hope, Portugal, Venezuela and Chili. 



Itl I ON I \ gen. nov. 



This genu's is erected for the reception of Cartodere unieostata, 

 which differs remarkably from every other Lathridiidi known to me 

 by its greatly developed trochanters, these being slender, cylindrical, 

 arcuate, and about equal in length to the fourth ventral segment. 

 This peculiarity, while suggesting Eumicrw and allies of the Scyd- 

 msenidse, is not as in these latter coupled with other traits which 

 may be considered of tribal value. Belonia is, in fact, in most re- 

 spects, a near ally to Cartodere, and only two supplementary char- 

 acters seem worthy of mention, viz. : the antennae are much longer 

 and more slender than in any Cartodere known to me, the interme- 

 diate joints (3-8) being so slender as to almost merit the term fili- 

 form ; and the prothorax is so small as to give the insect a very 

 singular apect. What weight to attach to these two character can- 

 not be determined without a wider knowledge of the exotic forms of 

 Cartodere than I now possess ; I suspect, however, that they will 

 prove to be of some significance. I take great pleasure in naming 

 the genus in honor of the distinguished French entomologist and 

 authority on the Lathridiidse of the world, M. Marie-Joseph Belon 

 of Lyons. 



B. unieostata, Belon.— Elongate, rnfotestaceous, glabrous. Head longer 

 than wide, finely, feehly, subrugosely punctate, and with a short faint longitudi- 

 nal impression; eyes small, prominent, situated at less than their length from 

 the hind angles; tempora convergent posteriorly ; sides before the eyes moder- 

 ately convergent; epistoma expanded to a width equal to that of the head with- 

 out the eyes; labrum suhtruncate; antennae distant from the eyes, inserted ante- 

 riorly beneath the finely margined sides of the front, passing the hind margin 

 of the prothorax ; first joint subglobular, second a little narrower, elongate-oval ; 

 3-8 nearly filiform, the third more than three times as long as wide, the following 

 joints gradually very slightly shorter; club 3-jointed, joints all longer than wide. 

 Prothorax about as long as wide, not wider than the head including the eyes,
