300 MAXDIBULATA. COLEOPTERA. 



Black, rather shining, pubescent; with the lateral margins of the thorax pale-: 

 rufous : the margin and apex of the abdomen and the mandibles the same : 

 the legs entirely black; the two basal joints of the antenna beneath pale- 

 rufous ; the remainder black. 



Distinguished at once by having the lateral margins only of the thorax bright- 

 rufous, with the rest of the thorax and the legs totally black. 



Rare in the south of England, but apparently not very uncommon 

 in the north. 



2. Antennae with the second joint shorter than the third. 



Sp. 22. cyaneus. Ater, nitidus, pubescens, capite antics, thorace ubdomineque rufis, 



elytris cyaneis. (Long. corp. 6 — 8 lin.J 

 Te. cyaneus. Curtis, vi. pi. 215.— Te. tricolor. Steph. Catal. 132. No. 1338. 



Shining-black, pubescent: head anteriorly, thorax and abdomen rufous: elytra 

 cyaneous, rugose, with three obscure lines on each : palpi and apex of the 

 mandibles dusky-black : basal joint of the antenna? rufous beneath, the apex 

 and rest of the antenna black. 



Known from the following species, with which it has been confounded, by its 

 entirely black legs :— Marsham long since applied the name tricolor thereto, 

 which has ridiculously enough been changed to the appellation it now bears : 

 it may be the cyanipennis of Ziegler, a more apt designation. 



t Sp. 21. longicornis. Luteus, elytris testaceis, apice nigris, antennis longitudine 



corporis. 

 Ca. longicornis. Fabricius, E. i. 302. — Te. longicornis. Curtis, fo. 215. (!) — 



Steph. Catal. 411. No. 1337.* note. 



Luteous, with the elytra testaceous, black at the apex, the antennseas long as the 

 body. 



Introduced as British in the work above cited, but evidently without any au- 

 thority : the insect here described is Brazilian, and the blunder originated 

 from the misapplication of my MSS. name of longicornis, in an endeavour 

 to conceal its origin. 



t Sp. 23, violaceus. Niger, capite, thorace, ahdomine pedibusque rufis, elytris 



cccruleis, antennarum ariiculo primo pallido. 

 Ca. violacea. Paykul. — Te. violaceus. Wilkin (!) — Steph. Catal. 132. No. 



1339. notes. 



Black, with the head, thorax, abdomen and legs rufous, the elytra cyaneous, the 

 basal joint of the antennae pale : the crown of the head more or less dusky in 

 the male. 



Introduced by mistake for the preceding insect in Wilkin's Catalogue of the 

 rare insects contained in his collection.
