ccvi Mr. Wollastons Descriptions of New Insects. 



4. 



A very peculiar little Homalota, somewhat allied to the H. gregaria of 

 Erichson, but smaller, narrower, more diluted in colouring, and with its legs and 

 antennae (especially the latter) extremely slender. It is certainly unrepresented 

 in the Stephensian collection, and I am informed by M. Kraatz, of Berlin, that 

 it is probably distinct from anything described in Erichson's Monograph. It 

 would appear to be a mountain species, the only two specimens which I have 

 seen having been captured by myself in North Wales (I believe at Bettws-y-coed) 

 during July. 



Family — Lathridiad^e . 

 Genus — Corticaria. 



CORTICARIA BOREALIS, Woll. 



Subovato-cylindrica, rufo-ferruginea, pabescens ; capite prothoraceque profunde 

 punctatis, Mo lato ocidis magnis exstantibus, hoc ad later a rotundato et 

 valde crenulato ; elytris profunde striato -punctatis, singulo stria fortiore 

 suturali ultra medium impresso, sutura scutelloque scepius nigrescentibus. 

 {Long. corp. lin. 1 — 1|.) 



Somewhat ovate-cylindrical, being convex, but a little expanded behind the 

 middle ; reddish ferruginous, slightly shining, and more or less clothed (especially 

 on the elytra) with a pale rigid pubescence. Head and prothorax deeply punc- 

 tured ; the former very wide, and with the eyes large and prominent ; the latter 

 convex, rounded at the sides, and with its extreme lateral edges powerfully 

 crenulated. Elytra coarsely striate-punctate, each of them having a more deeply 

 impressed stria alongside the suture, behind the middle ; the suture (particularly 

 behind the middle), and occasionally the lateral margins also, together with the 

 scutellum, more or less black. Antennae and legs a little paler than the rest of 

 the surface. 



The above description has been compiled from three specimens of a large, and 

 apparently new, Corticaria, in the possession of G. K. Waterhouse, Esq., of the 

 British Museum, which were captured many years ago by Charles Darwin, Esq., 

 though in what locality I am unable to ascertain, I possess, however, two ex- 

 amples, taken by Mr. Hardy on the coast of Durham, and (if I mistake 

 not) registered as the C. crenulata in his enumeration of the insects of that 

 county and of Northumberland. It seems to be undescribed in Mannerheim's 

 Monograph of the genus, and unnoticed in the ' Catalogus Coleopterorum 

 Europae,' published at Berlin in 1852. I may add, that on the return of M. 

 Motschoulsky to- St. Petersburgh, after his visit to England in 1851, I took the 

 opportunity of sending it for comparison with his large assortment of Manner- 

 heiins types, with none of which it would appear to agree. It is a very singular 

 and well-marked species, its cylindrical outline, wide head and prominent eyes, in 

 conjunction with its usually darkened suture (which his a deeply impressed stiia
