clothed, and its slender limbs, will at once separate it from both of 

 the preceding species. And it is somewhat remarkable that, whilst 

 the M. costipenne and M, hirtum would seem to represent, at the Cana- 

 ries, the Madeiran M, oceanicwm and M. ahdominale respectively, the 

 present one may be regarded as the analogue of the M. Artemisice of 

 those islands. And yet, in spite of this general resemblance, it is 

 abundantly distinct from it specifically. Thus, it may be known 

 by its larger size and more anteriorly acuminated outline, by its 

 pubescence being comparatively short and decumbent (instead of 

 long, fine, and erect), by its prothorax being much narrower, less 

 abbreviated, and more conical, by its entire sculpture being closer 

 and less coarse, and by its male antennae being very much shorter 

 and with each individual joint considerably less developed. 



The M.Jlavescens was captured by myself in the mountains of 

 Palma, from off the perpendicidar rocks which bound the great 

 Pinal, above the plains of Los Llanos, in the district of the Banda, 

 at the beginning of June 1858. 



XXXII. — Descnptions of new Genera and Species of Phytophaga. 

 By J. S. Balt. 



Fam. Eumolpidse. 

 Genus Pyropida. 



Corpus oblongum, valde convexum. Caput perpendiculare, subelongatmn ; 

 ociilis renifoi-mibus ; antemiis filiformibus, gracilibus, longitudini cor- 

 poris fequalibus, aut fcemince vix brevioribus ; mento apice angulato- 

 emarginato ; palporum articulo ultimo ovato, obtuse trancato. Thorax 

 longitudine latitudini fere sequali, dorso valde convexo, lateribus mar- 

 ginatis, breviter rotundatis. Elytra basi thorace multo latiora, apicem 

 versus angustata, obovata, basi truncata ; punctato-striata, humeris 

 prominulis. Pedes modice robusti ; femo)-ibm pauUo incrassatis, basi 

 attenuatis, inermibus ; tibits jwsticis quatuor extus ante apicem eiiiar- 

 ginatis ; unguiculis basi dentatis. Prostermim latum, transversnm, lateri- 

 bus medio paullo productis ; antepectoris processu antero-Iaterali anguste 

 cuneiformi, extus ad thoracis angulum exteriorem non extenso. 



Type Pyropida sumptuosa, Baly. 



This lovely insect is very closely allied to Chrysopida, agreeing 

 with that genus (and differing from Rhyparida) in possessing a narrow 

 wedge-shaped antero-lateral process to the antepectus, differing in 

 the shorter, more robust form, in the shorter legs (the thighs being 

 also less incrassate and unarmed beneath), and also in the somewhat 

 shorter, less exserted head and less prominent eyes.
