The male characters also difier, the male organ in the latter insect 

 being much more slender than in the former, and being parallel-sided, 

 whereas in L. cinnamomea it is slightly conical in shape, being broadest 

 at the base. Taking all the characters into consideration it would seem 

 that L. anglica ought to be regarded as a good species. 



Ij. lucens, Fairm. (Ann. Soc. Ent. Franc. 1855^ Ixxvi. ; Jacq. 

 Duval Gen. Col. d'Eur. i. pi. 36, f. 179 .t 11%). Mr. Champion 

 (Ent. Mo. Mag. xli. (2 Ser. xvi.) 1905, 198) points out that the insect 

 somewhat doubtfully introduced into the British list under the name of 

 L. ohlomja, Er., is really to be referred to L. lucens, Fairm. It belongs 

 to a different section of the genus, and is separable from the members 

 of the L. cinnamomea group by the short row of punctures at the base 

 of the ninth elytral interstice, and the peculiar character of the armature 

 of the posterior femora of the male ; this is well shown by Jacquelin 

 Duval {I.e. supra) ; the apical tooth is obtuse instead of being sharply 

 hooked, and the median tooth is very large and angular. It has- 

 occurred at Farnham (Champion) ; Shiei'e, Surrey (Capron) ; Bradfield 

 and Wellington College (Joy); Woodhay in some numbers (DonLsthorpe). 



In the last European catalogue L. grandis, Fairm., is given as a 

 synomym of L. cmnamomea, Panz., while L. anglica, Rye, and L. oblonga, 

 Er., are regarded as A^arieties of that species. Ganglbauer regards- 

 L. oblonga, Er., as a separate species and further appears to be inclined 

 to think that L. grandis, Fairm., and L, anglica. Rye, are distinct 

 inter se and from L. cinnamomea (Kiif. der Mitteleurop. iii. 213). In 

 any case we do not appear to possess ohlonga as British. As a matter 

 of fact we have hardly, as yet, material enough to settle the question. 



L. davidiana, Joy (Ent. Mo. Mag. xlvii. (2 Ser. xxii.) 1911, 11). 

 Allied to L. dabia, Kug., but broader and more convex, the antennse 

 shorter, the head more strongly punctured, the thorax broadest at the 

 base, the scutellum much larger, and the stri?e of the elytra more finely 

 and closely punctured, the thii-d being distinctly sinuate in the centre. 

 Oval, strongly convex, ferruginous, head and thorax darker, often 

 fuscous ; head rather strongly punctuied, antennfe rather short, tes- 

 taceous, with the club fuscous, the latter rather narrow, with the last 

 joint about as broad as the penultimate ; thorax broadest at the base 

 (and not before it as in L. dAibia), finely and moderately difl:useiy 

 punctured ; scutellum large, thickly and strongly punctured ; elytra 

 rather short, rounded at the sides ; strite with fine and very closely set 

 punctures, third stria distinctly sinuate outwards in the middle, fourth 

 stria sometimes very slightly sinuate, first stria not reaching the base, 

 but ending at the side of the scutellum about 5- to | from its base, 

 instei'stices distinctly and not very finely punctured ; legs testaceous, 

 tibias strongly widened towards apex. 



Male with the posterior femora furnished at apex with a small 

 blunt tooth ; posterior tibi;e very feebly bisinuate, rather strongly 

 curved inwards at apex. L. 2^ to 3 mm. 



Southport, Deal and Llancillo, and probably fairly generally dis-
