chiefly from the prevalent disinclination io study minute insects, 

 and from their locality : the above may be called An, plumbeus^ 

 and as I have already described the British species of the genus 

 in a former volume of the Journal, I shall add the description of 

 a fourth species discovered by myself last July, at Ripley, ia 

 Surrey. 



Sp. 4. An. grisescens. Rufo-grisea, abdomine concolore, thorace 

 fascia dorsali albidd^ lateribus nigrkantibus^ alts submacu-' 

 laiis. (Long. corp. 3| lin.) 



Red-griseous ; forehead white ; thorax with a broad longitu* 

 dinal whitish band, edged on each side with dusky; pleuros 

 rufescent ; abdomen plain, griseous, not annulated : legs^ palpi^ 

 and antennae pale olivaceous ; wings nearly immaculate; nervures 

 pale yellowish. 



The remarks upon Haltica have novelty to recommend them* : 

 at least I am unacquainted with any work in which they are men- 

 tioned, unless they are given in lUiger's Magazine, in the 7th 

 vol. of which work there is a long dissertation on the genus, with 

 descriptions of all the then known species; but, unfortunately, 

 with the exception of the specific characters of the latter, and the 

 characters of the sections, the work is in German. Halt, Mer- 

 curialis decidedly will not associate with the other species above 

 named, which constitute lUiger's section Aldtarses, and are ele- 

 vated to the rank of a genus in Latreille's Families Naturelles. 



I shall conclude by stating that Latreille, in the work last men- 

 tioned, places the Dermestes Armadillns of De Geer, in his section 

 Monomera; but I suspect from its close affinity to Phalacrus^ 

 Agaihidium, and Leiodes^ that it is peutamerous, though I have 

 hitherto been unable to examine the insect with the requisite 

 microscopic accuracy, owing as well to its minuteness as to the 

 fact of possessing a single specimen only; it and two other 



* It may, however, be observed, that the second joint of the antennae is 

 usually the shortest in Coleopterous insects.
