Lfljitusa.'] STAPiiYLrNrn.ii. 1G5 



The lurva of L. fiim'uhi is sii'ul to be fomiil ii» the gullerii's of Cerylon, ami that 

 of Z. analis in the galleries of Tomicux, but it is prolmblo that neither of tlieiii are 

 coiitiiied to any pariicuhir insect. 



According to our catalogues there are four British species of tliis 

 genus ; hut two of these, L. tmiacea and L. rujic(illi-<, behjug respectively 

 to tlie sub-genera Sipalia, Rev, and FarJn/ghda, Thonis. : many of the 

 continental authorities unite these as sub genera under Lepftisa, but they 

 seem to be very distinct from that genus ; the differences, however, 

 between L tetftacea and L. rujicollis are very slight, consisting chiefly 

 in the relative sharpness of the mesosternal plate. The difference as 

 expressed by Mulsant and Rey is as follows: Sipulia, "Lame mcso- 

 sternale retrecie en angle aigu ; " Par/i/jf/luta, " Lame niesosteniale re- 

 trecie en pointe aceree," and I have therefore united them under Sipalia. 

 The genus Leptusa, as tlius restrictetl, contains only four or live Euro- 

 pean species. 



I. Thorax hardly narrower than elytra; colour brown or pitchy, 



rather dull ; antennse ferruj>;inous or reddish testaceous . . . L. ANALIS, Gj/ll, 



II. Thorax plainly a little narrower than el;, tra ; colour pitch-black, 



shiny; antenna; pitcliy wilh base lighter L. fumida, Er. 



Xi. analis, Gyll. Of an obscure pitchy red or brownish-red colour, 

 with the head and part of hind body before apex darker, finely and rather 

 thickly pubescent ; head much narrower than thorax, antennre moderately 

 stout, slightly thickened, ferruginous or reddish-testaceous, with penul- 

 timate joints strongly transverse ; thorax plainly broader than long, 

 about as broad as elj^tra, finely and thickly punctured ; elytra longer 

 than thorax, thickly and rugosely punctured, the punctuation being 

 evidently stronger than that of thorax ; hind body long, parallel-sided 

 until near apex, finely and thickly punctured in front, sparingly behind, 

 basal segments strongly impressed longitudinally ; legs clear reddish- 

 testaceous. L. 2| mm. 



Male with the sixth segment of hind body furnished with a long 

 longitudinal keel, seventh with a more or less distinct keel, apical 

 margin plainly sinuate. 



Local ; Scotland, Highlands, under bark of fir ; Tay, Dee, Moray, and Solway 

 districts : Mr. VV. G. Blatch tells me he has taken it in the Dean Forest, which is 

 hitherto the only English record. 



Ii. fumida, Er. (hrnnorrhoifJaUs, Heer), Blacker and mure 

 shining than the preceding, with lighter and less close pubescence ; it 

 is, moreover, a shorter and stouter insect ; the antenme are a little 

 longer in pro])Oition, and are fuscous with base lighter ; the thorax is 

 evidently narrower tlian the elytra, and the hind body is less elongate • 

 the male characters also are different, the sixth segment being furnished 

 with a small tubercle instead of a long keel, and the seventh being less 

 strongly sinuate and sometimes obsoletely crenulate at apex. L. 2] -2,' 

 mm. 



Under baric, ic. ; cummoa and widely distributed throughout the country.
