seems to have been puzzled by his insect, as it was revei'sed among 

 some large specimens of 0. parallelus at the end of his series of that 

 species. It differs, however from large examples of paraJlehis by the 

 less distinct basal margin of the thorax, as well as by a slightly 

 different shape and punctuation of that part.

A TABLE OF THE BRITISH SPECIES OF LACCOBIUS, Er. 

 BY JAMBS EDWARDS, F.E.S. 



The following table suggested itself in the course of the writer's 

 arrangement of his material in this genus, and its publication is 

 prompted by the consideration that no table of our species has 

 hitheiio appeared in which the character of the ^J specula, discovered 

 by Dr. Sharp, has been utilized in the grouping of them ; moreover, 

 two species have been added to our list since the publication of 

 Mr. Newbery's table (Ent. Mo. Mag. xliv, p, 80). 



1 (12). t? with a pair of flat smooth shining spaces (specula) on the under 



side of the front edge of the labruni. Rows of elytral punctures 

 irregular. 



2 (7). Specula sub-circular. Surface of the pronotura smooth on the disk. 



3 (6). S vv'ith a patch of yellow pubescence on tlie hinder basal angle of the 



middle femora beneath. 



4 (5). Elytra without metallic reflection. The dark patch on the pronotiun 



touching the hind margin in its two inner fourths and having a more 

 or less V-shaped projection on each side in front. Clypeus often 



narrowly pale at the sides nigriceps, Thoms. 



{sinuatiis. Fowler, nee Motsch). 



5 (4). Elytra with purple metallic reflection. The dark patch on the 



pronotum occupying the whole surface except a narrow side border, 

 which sometimes has a dentiform projection near tlie apical third of 

 its inner edge directed obliqviely backward, Head entirely dai'k 

 above purpiirascens, Newbery. 



6 (3). <? without a patch of yellow pubescence on the underaide of the 



middle femora. Pronotum black with irregular yellow side margins, 

 which have a dentiform projection neai- the apical third of the inner 

 side, and sometimes an oblique linear one i-unning from the inner 

 apical angle towards the middle of the disk. Head entirely dark
