CEOTCHIA. 29 



hairy beneath. Elytra very smooth, the striae fine and the punctures minute; the 

 suture a little depressed at the apex; their apices simple as in Languria proper, and 

 passing the end of the abdomen. Ventral apical segment simple, and with scattered 

 punctures. Abdominal lines present, short, very fine, divaricating. Second, third, and 

 fourth segments of the abdomen with a punctiform tubercle on each side giving rise 

 to an upright seta. 



The three-jointed club and coarsely granulated eyes alone indicate that this is a 

 very distinct genus from any other New-World form of the " Languriides." The 

 typical speoies are of medium size, but others are small and more filiform ; while 

 the smallest members of the whole group which I have yet seen (these being scarcely 

 two millimetres in length) find their location here. The six species described by 

 Mr. Fowler are all from the late Mr. Crotch's or my own collection, and are all from 

 Tropical South America. There is good ground for believing that this will prove one 

 of the most numerous in species of the genera of the subfamily. 



1. CrotcMa proxima. (Tab. I. figg. 24 *, 24 a, 6 ; 24 3, d 1 front tarsus ; 24 c, 

 2 front tarsus.) 



C. vagabundce (Fowler) summa affinitate et primo visu haud differens, angulis autem prothoracis magis callosis 

 parum reflexis ; nigro-senea, nitidissima ; eapite parce sat profunde, prothorace minute, punctatis, hoc 

 quadrato, basi sinuato, subtiliter marginato, angulis anticis subrectis, angulis posticis acutiusculis, lateribus 

 fere rectis marginatis; elytris quam prothorax parum latioribus, minute punetato-striatis, interstitiis 

 planis et lsevibus. Long. 8| millim. 



Mas tarsis anticis latis, longius villosis ; abdominis segmentis tribus intermediis puncto duplici setigero 

 instructis. 



Fernina tarsorum anticorum articulo basali multo minore, minus villoso. 



Hab. Panama, Bugaba, Volcan de Chiriqui, David (Champion). 



Although this species is so very close to the one from Brazil lately described by 

 Mr. Fowler from two specimens in my own and Mr. Crotch's collections, yet a close 

 comparison of the type with a long series of examples brought by Mr. Champion 

 from the State of Panama convinces me that our insect must be regarded as distinct. 

 C. proximo, is rather larger ; the thorax is quadrate, its disc more finely, scarcely 

 visibly, punctate, and the anterior angles are a little more clearly refiexed so that they 

 appear more prominent. 



The species of this genus seem only to be differentiated by very minute distinctions, 

 as, indeed, is the case in all the genera of " Languriides." I have not seen any speci- 

 mens in our series of C. proxima that could be referred to C. vagabunda ; though had 

 these insects both occurred in the same country they might have been treated as mere 

 varieties. According to this view C. punctata, described by Mr. Fowler as a variety,, 

 and other varieties spoken of by him, would be regarded as distinct species. 



* By an oversight this figure is numbered 25 on the Plate.
