ovate species, and is distinguished by having the thorax move convex than the 

 elytra, by the very fine, and at the same time diffuse, punctuation of the thorax, and 

 by the ahnost invisible punctuation of the interstices of the elytra. There is a 

 specimen in Mr. Mason's collection which was returned to me from the continent as 

 "pres ruhiginosa ;" it is not sufficiently distinct to form a new species, but must, T 

 think, be roferred to A. ruliginosa. 



It may, perhaps, be here remarked that A. oblonga, Er., and A. grandis, Fairm., 

 are now united by the chief continental authorities, and also that A. oSesa, Schmidt, 

 appears to be considered as in all probability identical with A. dulia, Klug, and A. 

 similata, Eye, as a form of A. hadia, Sturm. 



Very little is usually known about the difference between Cyrtusa mmuta,Ahv., 

 and C. jyatixilla, Schm. : the former is a larger, less elongate, and more convex insect, 

 with the posterior tibise gradually widened to apex, and the posterior angles of thorax 

 right angles ; it has been taken at Scarborough and in the Solway district of Scotland, 

 but very rarely ; (he latter is evidently smaller, more elongate, and less convex, with 

 the posterior tibiae abruptly widened at apex, and the posterior angles of thorax 

 obtuse ; it is not uncommon in the London district in several localities, and has been 

 taken at Hastings and in the New Forest. Most of the specimens standing in our 

 collections as C. minuta ought probably to be referred to C. pauxilla. 



Adalia (Coccinella) obliterata, L., var. fenestbata, "Weise. 

 In Dr. Power's collection there are two specimens of this very distinct vai-iety 

 of Adalia obliterata, L. : it is quite black, with the apex of the elytra and a few 

 more or less distinct spots at margins and on disc of the same yellowish or yellowish- 

 red, and the anterior angles of the thorax somewhat broadly whitish. 



The specimens were taken at Northampton, on ling, by the Eev. 

 Hamlet Clark. 



A. BOTUNicA, Payk., var. ceucifeba, Weise. 

 Most Coleopterists who are acquainted with Dr. Power's collection will remem- 

 ber a rather small, hemispherical, yellowish Coccinella labelled "like variabilis, but 

 not it," which Dr. Power used to set great store by, and often endeavoured to get 

 identified : this specimen has lately been named for me by Herr Reitter as Adalia 

 hothnica, v. crucifera, Weise, a species which occurs in northern Europe, the 

 mountainous districts of central Europe, and in Siberia. Dr. Power's specimen is from 

 Moss Morran, Scotland. The genus Adalia differs from Coccinella proper in having 

 the prostei-num convex, and without carinse, whereas in the latter genus the pros- 

 ternum is depressed between the coxte, and furnished with two carina! ; hitherto 

 only two species have been known as British, A. ohliterata and A. bipunctata. A. 

 hothnica is ahnost circular and hemispherical. Head and thorax yellow, with 

 distinct black markings, which are more or less confluent ; elytra yellow, with the 

 suture and six patches on each black ; the side margins also, until a third before 

 apex, are black ; in the variety two of these patches on each elytron are free, two 

 join the margin, one touches the apex, and one the suture at middle : the suture 

 and the two patches that join it form a rough cruciform figure ; the legs are pitchy ; 

 the elytra are closely and rather distinctly punctured. Length, 3i — 4 mm.
