joints together ; and the middle tibia is slightly curved and its inner 

 margin is armed along the anterior edge with a series of well-marked 

 crcnulatioiis. There can be little doubt, I think, as to the present 

 species being P. crenidatus, Pandelle, this name being placed in the 

 Catalogues as a synonym of P. limbatus, Maklin, a Sitkha insect. 

 The distinctive characters of P. limbatus have never, so far as T know, 

 been satisfactorily set forth. It differs from the allies, inasmuch, as 

 the male patella is formed by the elongation of the basal joint, 

 whereas, in P. brevicollis, tiie basal joint is comparatively shorter, 

 and in P. brochypterus the patella is altogether smaller. The name 

 of this insect must, I fear, remain a little doubtful, as none of the 

 describers allude to the above mentioned diagnostic feature. In 

 each of the three species the second joint is more or less enlarged, 

 but it is only in the species I am specially alluding to that the first 

 joint is so predominantly elongated. 



I found two specimens of this species at Nethy Bridge in 1906, 

 and two others in 1907. P. crenulatus is not specially a northern 

 insect.

THREE NEW BRITISH C OL EOF T ERA. 

 BY NORMAN H. JOT, M.E.C.S., F.E.S. 



Epipeda nigbicans. Thorns. 



Depressed, black ; head, thorax and elytra somewhat shining, alulaceous, and 

 very fi:<ely and diffusely punctured ; head nearly as broad as thorax, strongly 

 channelled in centre ; antennae short, black with base pitchy, third joint shorter 

 than second, fourtli strongly transverse ; tliorax transverse, distinctly channelled • 

 elytra half as long again as tliorax ; abdomen more shining than front-parts, basal 

 segments very flnely and diffusely punctured, the last two segments almost 

 impunctate ; legs pitchy-testaceous, femora darker. L. 2-u mm. 



This species is easily distinguished from E. plana, Gyll., by its 

 darker colour and distinctly more shining fore parts ; the head is 

 larger and much more finely and diffusely punctured, and the head 

 and thorax are strongly channelled. Two specimens were taken 

 under pine bark, at Blair Atholl, Perthshire, on September 5th, 1909, 

 It occurs in Sweden and Finland. 



Latiirobium dilutum, EricJis. 



Somewhat resembling L. longulum, Grav., but larger and broader in proportion, 

 entirely brownish-testaceous, anlenuoe and legs reddish-testaceous ; head larger than
