NEW BKITISH SPECIES, ETC., IN 1865. 75 



2 — 5 lightly impressed; coxae short, like the preceding, but 

 produced into a curved spine on the inner margin. Fern, 

 Elytra simple. 



4. C. mtermediuSf Kr., Bris. Abdomen with segments 

 4 — 5 lightly impressed ; coxae long, gouge-shaped. Fern, 

 Elytra simple. One specimen, from Mr. Janson's collection, 

 taken at Finchley, 



The males, as Mr. Crotch remarks, may be always known 

 by the dilated anterior tarsi and curved intermediate tibise.

I see in the last edition of de Marseul's Catalogue that 

 the Catops lojigulus of Murray {tristiSj var. B, Mon. of Gen. 

 Catops, 36) is synonymous with pilicornis, Thomson, Skand. 

 Col. iv. 61, and distinct from the present species; a conclu- 

 sion in accordance with my own suspicions. The C. longula 

 of Mr. Crotch's Catalogue, being founded (as that gentleman 

 informs me) on Murray's insect, will, therefore, now stand as 

 jnlicorniSf Thorns. ; and the above species, first recorded by 

 me, will immediately precede it in our list. 



It is allied to C. morio, nigrita, coracina, and tristis; 

 from which, besides its much more elongate form, the follow- 

 ing characters will distinguish it. 



Compared with rnorio the club joints of the antennae are 

 longer, the 7th being in every way larger, and the apical 

 half only of the 11th testaceous; its elytra are more evi- 

 dently punctured, and more gradually contracted behind ; and 

 its legs (and especially the apical joints of its tarsi) are longer. 



It may be known from C. nigrita by its thorax being 

 broadest a little before the middle, with the posterior angles 

 less straight ; from C. coracina by its uniformly stouter
