Lanyt-landiina.'] CLAVICOKNIA. 193 



Langelandia (Ac/elandia) grandis, which undoubtedly has four joints to 

 the tarsi ; this species is very closely related to Lanfjdandia anopkthalma, 

 and cannot be separated far from it ; if then this latter species has 

 3-jointed tarsi, great confusion arises as to the proper classification. M. 

 Belon rather inclines to the plan of classing the Colydiidw and Lath- 

 ridiidae together under one family, so as to include the groups with three 

 joints to the tarsi as well as those with four joints ; the only other plan 

 to be adopted (if Langelandia has 3-jointed tarsi, which does not seem 

 as yet to be proved with absolute certainty) is to form a separate family 

 Langelandiidse ; as, however, M. Belon observes, it appears " exorbitant 

 de leur donner rang de famille ; " if, however, they are not given family 

 rank, I feel certain they must be classed with the Colydiidte, as they bear 

 a far greater affinity to such genera as Ditoma than to any of the Lath- 

 ridiidze. 



XiAN GEXiANDXA, Aube. 



This genus contains four European species, one of which has quite 

 recently been found in Britain ; they are characterized by having no 

 eyes, and by the fact that all the coxae are more or less distant ; they are 

 usually found in rotten wood, seed potatoes, &c., buried at some distance 

 underground. 



The larva of L. anopHhalma is described by Ferris (Larves des Coleopteres, p. 77) ; 

 the description, however, does not quite agree with that of a larva taken by Mr. T. 

 Wood in company with the perfect insect, and which I feel certain is the larva of 

 Langelandia ; Ferris describes the larva as linear, but the larva before me is strongly 

 strangulate in the middle of body, and the abdomen is widened behind and terminates 

 in two strong pointed processes ; Peiris states that the larva is linear, and that the 

 abdominal segments are gradually larger until the sixth, and that the ninth terminates 

 in two moderately curved hooks ; the pupa appears to be distinguished by having the 

 large flat head resting on the thoracic region. 



Zi. anophthalma, Aube. Elongate, subparallel, not convex, of a 

 dull ferruginous colour ; head much narrower than thorax, uneven ; 

 antennae short and stout, with distinct 2-jointed club ; thorax much 

 longer than broad, widest a little before apex, slightly narrowed to base, 

 anterior angles produced, posterior angles obtuse, lateral margin bordered 

 and more or less strongly crenulated, disc with three more or less distinct 

 longitudinal keels ; elytra with the suture and two lines on each raised, 

 the intervals being more or less coarsely punctured in rows ; legs ferru- 

 ginous. L. 2|-3| mm. 



This species has only been recently discovered in Britain by Hr. T. Wood, who took 

 it in his garden at St. Peter's, Kent, in decaying seed potatoes underground, and where 

 I had the pleasure of taking it with him last summer (1830) ; the insect is extremely 

 sluggish in its movements, and might be easily overlooked. 



CERYLONINA. 



This tribe contains two European genera, Pltilotltermus and Ccri/lon,
