LATHRIDIIDiE. 



LATHRIDIUS, Heibst. 

 L. bergrothi, Reitt. (Yerh. zool.-bot. Ges. Wien, 1880, 53). In 

 gener.al appeaiance something like Enicmus transrers^ls, 01., but at 

 once distinguished by its larger size, and the sharply carinate interstices 

 of the elytra (there are three prominent carina3 on each elytron and the 

 suture is also raised), the margins of the latter being also conspicuously 

 explanate towards base; according to Ganglbauer (Die Kafer von 

 Mitt. Eur. iii. 781), the chief distinguishing point between this and 

 allied species seems to be that on the posterior half of the elytra 

 between the last raised interstice and the side maigin, instead of the 

 usual double row of punctures there are four rows ; this is very 

 evident vmder a good lens ; the upper surface is somewhat dull, ferru- 

 ginous, with the head and thorax usually darker, without pubescence ; 

 head narrower than thorax, with rather small prominent eyes ; antenna3 

 with a feeble club ; thorax about as long as broad, gradually nan-owed 

 behind apex, sub-parallel behind, finely rugose ; elytra ample, ovate, 

 much broader than thorax, carinate and with the interstices punctured ; 

 legs red. L. 2-2J mm. 



Four taken by Professor Carr from a dried specimen of Burdock 

 (Aretinm) in the herbarium of the University College, Nottingham, 

 and introduced as British by the Bev. A. Thornley (Ent. Mo. Mag. 

 xxxvii. (2 Ser. xii.), 1901, 18) ; afterwards taken in numbers by Mr. W. 

 Holland in his cellar at Oxford by beating firewood faggots and 

 lumber. London in a granary (Donisthorpe) ; Reading and Wells, 

 Norfolk (Joy) ; Southampton (Gorhnm) ; Winlaton, Durham (Bagnall) ; 

 Chesham (Eiliman) ; Loudwater, Bucks, in moss (W, E. Sharp) ; Carlisle 

 (Day) ; West Malvern (Tomlin) ; Plymouth (Keys). It is gradually 

 spreading its range on the Continent ; it was not described vintil 1880, 

 and has been found in Russia, Denmark, Germany, Austria, Silesia, 

 and France. It has comparatively recently been described, as pointed 

 out by Mr. Holland, as having been found in an old straw hat at 

 Wimereux, Pas de Calais, and in old baskets in Normandy. 



ENICMUS, Thomson. 



E. fungicola, Thorns. (Skand. Col. x. 33G). Pitchy black, with 

 the elytra reddish-brown and the antennfe and legs ferruginous ; head 

 obsoletely channelled, with the eyes large and prominent ; thorax a 

 little shorter than broad, scarcely cordate, with the sides dilated before 

 the middle and obsoletely crenulate, central longitudinal channel more 

 or less distinct, elytra about twice as broad and four times as long 

 as thorax, slightly shiny, with veiy finely punctured strife, which, with 

 the exception of the strong sutural stria, become obsolete towards 

 apex ; underside pitchy black. L. l|-2-| mm.
