. the base testaceous, the apex slightly mcrassated, with the terminal joint 

 rather elongated and acute. 



Not common: found within the metropolitan district in the spring, 



Sp.170. humeralis. Nigricans, thorace canaliculato, pedibus, pectore, abdomine 

 basi ut apice elytrorumque humeris ferrugineis. (Long. corp. 2 J — 3 lin.) 



Al. humeralis. Gravenhorst?— Steph. Catal. 268. iVo. 2767. 



Black, shining, dusky: head sub triangular, black: i/torajr broad, wider than

'- rufous: abdomen above twice the length of the elytra, ferruginous, with,

Sp. 171. funesta. Nigra, nitida, palpis antennis pedibusque fuscis, thorace 



postice puncto impresso. (Long. corp. 2^ lin.) 

 Al. funesta, var. Gravenhorst, Mon. 168. 



Black, shining: head smaller than the thorax, subtriangular : thorax xaihev 

 wider than long, somewhat convex, with a small impression in the middle of 

 the hinder margin, which is rounded : elytra very delicately punctate, black, 

 with a griseous pubescence : abdomen deep glossj-black, with the margins 

 of the central segments rather testaceous : legs Tpitchj fuscous, with the 

 the tibiae anteriorly and the tarsi paler : antennce rather long,fusco-piceous, 

 with the base reddish, slightly incrassated towards the apex, with the ter- 

 minal joint elongate, subacute : palpi fuscous. 



This and the three preceding species appear to form a good genus. 



I possess a single example of this conspicuous insect, which I 

 believe was captured by myself at Hertford.
