hura.'] PHTTOPHAOA. 281 



broader and has the lateral tubercles more prominent and continued with 

 a slight curve until they meet the anterior margin ; the elytra are thickly 

 and strongly punctured, and the separate side margin is furnished with 

 a row of fine and often obsolete punctures. L. 3^ mm. 



On young birches and aspens ; very local ; Tay, Dee, and Moray district! ; it was 

 first discovered by Charles Turner at Rnnnoch, and was named after him by Dr. 

 Power; the name was afterwards sunk in favour of rvfo-textacea, Kraatz, by certain 

 European authorities, but in the catalogue of Heyden, Beitter, and Weise it is re- 

 instated ; it is sometimes abundant where it occurs ; I have a note from the Rev. 

 C. T. Cruttwell, in which he records it as found by himself " in the utmost profusion 

 on young aspens at Pitlochry, end of August, 1884." 



XiEMA, Fabricius. 



This is one of the largest genera of the Coleoptera in point of numbers ; 

 more than five hundred species have already been described, about ninety 

 of which have been added since the publication of the Munich catalogue; 

 they are chiefly found in tropical countries, and are very widely distri- 

 buted ; only eight occur in Europe, of which four inhabit Britain ; they 

 are closely allied to Crioceris, from which they differ in having the tarsal 

 claws connate, and the head contracted behind into a shorter neck ; the 

 eyes are emarginate ; the scutellum is truncate at apex ; the elytra are 

 oblong, variable in breadth, and as a rule much broader than thorax. 



I. Upper surface entirely blue or greenish-blue. 



i. Thorax constricted just behind middle L. CYANKLLA, L. 



(puncdcollis, Curt.) 

 ii. Thorax constricted just before bnse. 



1. Size smaller; elytra shorter in proportion to thorax, 



which is more strongly constricted behind . . . . L. LICHEXIS, Voet. 



(cyanella, Suffr.) 



2. Size larger ; elytra longer in proportion to thorax, 



which is very slightly constricted behind . . . . L. ERICHSOKI, Suffr. 



II. Thorax bright red L. MBLANOPA, L. 



It. cyanella, L. ( puncticollts, Curt.). Rather broader and more 

 convex than either of the three following species, of a deep blue colour, 

 shining, antennae and legs dark; head much contracted behind eyes, 

 which are large and very prominent ; thorax about as long as its greatest 

 breadth, strongly constricted behind middle, rather strongly and not 

 closely punctured, with a smooth and somewhat raised central line ; 

 elytra much broader than thorax, with rather fine rows of punctures, 

 interstices very finely crofs-striated ; the colour is variable, being 

 occasionally violet or blackish. L. 4-5 mm. 



Male with the anterior tarsi slightly dilated.
