Sp. 4. variabilis. Piceo-ferrugi?ieus, elytris nigro-piceis, basi maculisque fer- 

 rugineis, antennarum articido ultimo longiori, pallida. (Long. corp. 2 — 9.\

My. variabilis. Hellwig.—Steph. Catal 88. No. 916. My. piceus. Curtis, iv. 

 pi. 156. 



Pitcby-ferruginous or black, the antennse dusky- ferruginous, with the last joint 

 large and pale ochraceous : elytra pitchy-black, faintly punctate-striate, and 

 slightly pubescent, the base with a broad ferruginous belt, in which is a sub- 

 quadrate dusky or black spot ; surrounding the scutellum, behind the middle, 

 is a variable, abbreviated testaceous fascia, sometimes simple, at others arcuated 

 or truncate, with a minute adjoining spot; and near tbe apex is a rounded 

 spot of variable dimensions and similar colour : body pale fei ruginous beneath : 

 legs slender, ferruginous, or pale testaceous. 



Extremely variable ; especially in the form and markings of the spots on the 

 elytra, scarcely two individuals agreeing precisely with each other : the spots 

 and fasciae being more or less confluent, and variable from testaceous to light 

 ferruginous ; the ground colour is also frequently black, and sometimes pale 

 ferruginous. 



Occasionally taken within the metropolitan district, also in Devon- 

 shire, near Bristol; in Norfolk, Suffolk, &c. " In the neighbour- 

 hood of Swansea."— L. W. Dillwyn, Esq. " Netley."— Rev. F. W.

Sp. 5. Populi? Rufo-ferrugineus, subpuhescens, elytris pallidioribus, subtiliter 



punctato-striatis, mediis nigro ferrugineoque variis. (Long. corp. 2 lin.) 

 My. Populi? Fabricius f Steph. Catal. 88. No. 947. 



Rufo- ferruginous, slightly pubescent; thorax very obscurely punctate: elytra 

 pale, very delicately punctulate, faintly punctate-striate ; with an obscure 

 fascia in the middle, and a patch at the apex, fuscous : the latter with an ob- 

 solete pale spot : body beneath rufo-testaceous : legs pale rufo-testaceous, or 

 ferruginous. 



The insect answering to the above description in my cabinet is the Boletaria rufa 

 of Marsham, but it seems too closely allied to My. variabilis to be really distinct 

 from that species; its chief distinction consisting in the disposition of the 

 colouring on the elytra, and some trifling variation in form. 



One of my specimens was taken near London, the other I ob- 

 tained from the Marshamian cabinet : the insect has occurred in 

 Norfolk.
