elongatulus, Stui-m, Schaum, which is, I believe, new to the British Fauna. It 

 closely resembles H. trisUs, but is rather larger, flatter, and more obscure than 

 that species, and has a wider head and thorax, and the elytra more pubescent. 

 I have compared my specimen with continental types kindly lent me by Mr. Crotch, 

 with which it agrees in every respect, excepting in its slightly smaller size. —

Note on a new British Haliplus. — I occasionally find, in large ponds here, a 

 Hali2olus which I think is H. varms, Nicol., Schaum. It is of the same pale 

 testaceous hue as H. ohliqims, with the elytra lineated with black j the black lines 

 next the suture nearly complete, and those towards the margiu very slightly twice 

 interrupted. Its smaller size and proportionately larger and more convex thorax 

 separate it from H. ohliq;uiis, whilst the small size and pale colour clearly distinguish 

 it from H. lincatus, — Id. 



Note on Nomada xantlwsticta and Nomada mistura. — Nomada mistura, Smith 

 is, I believe, the male of Nomada ccanthosticta, Kirby. Both appear at the same 

 time of year, and frequent the same localities. Both Mr. Wailes and I have taken 

 thorn flying about the burrows of Andrce7ia analis, near Haltwhistle, Northumber- 

 land, in July. In the same month I again met with the Nomada near Naworth 

 Castle, Cumberland, also in company with the same Androina, — Id. 



Note on Nomada horealis. — The handsome Nomada horealis, Zett., is in this 

 district rather an abundant species, occurring wherever Andrcena Clarkella is to 

 be found. The Nomada varies very much both in size and colour : I have examples 

 not more than one-third the bulk of others, and in these small specimens consider- 

 able variations of colouring are to be found. Typically, the female has nearly a 

 totally black head and thorax ; but specimens are not unfrequent which are nearly 

 as much maculated with ferruginous as dark examples of ruficornis. The two 

 species, however, may be easily separated by the spines on the posterior tibise : in 

 ruficornis the tibiee can scarcely be said to be spinose, having merely a row of weak 

 pale-coloured hairs, whilst horealis has the tibiae thickly set with strong black 

 spiny hau's. In the latter, too, the head and thorax are of a deeper black, much 

 less pubescent, more glossy, and more distinctly impressed behind than in 

 ruficornis. 



Can it be that the great difierence in size of this species is caused by the size 

 of the Andrwna to which it is attached ? I have often taken it flying about 

 colonies of A. albicans, and in other places where there was no trace of its usual 

 patron, A. Clarkella; and would thence infer that it is not exclusively attached to 

 one, but adopts itself to several, species, as some of the other species of the genus 

 are known to do. — Id.
