20. Mieromimetes alutaceus, n. sp. (PI. XX. fig. 5.) 

 M. parallelus, subopacus, ubique alutaceus, minutissime et parce cinereo 

 pubescens, subamescenti-niger, prothoracis limbo postico, elytrorum 

 apice et margine angusto laterali, antennis in toto pedibusque flavo- 

 testaceis ; capite latiusculo, parce et minute punctulato ; prothorace 

 convexo, minutissime (vix perspicue) puuctulato ; elytris depressis, vix 

 distinctius punctulatis et multo subtilius alutaceis, pilis erectis fere 

 carentibus ; pedibus posticis interdum paulo infuscatis.

Although (as lately stated) perfectly distinct from it in real 

 structure, yet, regarding the present insect superficially as an Attalus 

 (for which it would, at first sight, be taken), I may just add that it 

 may be readily known from its apparent allies by its subopake and 

 entirely alutaceous surface ; by its dull brassy-black hue (which has 

 often a slightly greenish tinge), the hinder margin of the prothorax, 

 the extreme apex and lateral edges of the elytra, and the limbs 

 (except occasionally a portion of the posterior legs) being pale 

 yellow ; by its head and pronotum being convex, whilst the elytra 

 are somewhat parallel and depressed ; and by the latter being almost 

 entirely free from any indication of additional erect pile. The few 

 specimens which I have seen (only fourteen in number) were cap- 

 tured by myself, during April 1858, in the sandy district at Maspa- 

 lomas, in the extreme south of Grand Canary. 



21. Mieromimetes? jucundus, n. sp. 



M. nitidus, subglaber ; capite sat magno longiusculo convexo crasso, aeneo- 

 nigi-o, regulariter punctato ; prothorace rufo, in disco antico vix nigro 

 maculato, fere impunctato, postice angustato, mox ante basin (in medio 

 sub-bipartito elevatam) transversim constricto ; elytris cyaneis, minu- 

 tissime et parce punctulato-subrugulosis, pilis nigris erectis perpaucis 

 parce obsitis; antennis brevibus, nigrescentibus, versus basin rufo- 

 testaceis; pedibus anticis fusco-piceis, intermediis (tarsis exceptis) 

 paulo obscurioribus, posticis subnigrescentibus.

I would wish distinctly to state that I have placed the present 

 insect here merely provisionally, and not with the idea that it is 

 truly a second species of Mieromimetes ; but having unfortunately 

 only a single individual to judge from, and that a female, I am unable 

 to conjecture to what group the fore tarsi of its males would tend to
