250 INSECTA MADERENSIA. 



amongst flowers in the neiglil)oiu'liood of Fimclial, especially in low positions 

 towards the coast. On the rocky ledge above the Praya Formoza I took it in 

 tolerable abundance during March of 1848 ; since which time I have not succeeded 

 in detectuig it. 



§ III. Caput ovatum angustum depressum, clypeo longiore, oculis demissis : palpi maxilhres longksimi, 

 articulis secundo et tertio longiorihus : tarsi antici maris artieulo secundo in lohum elongatum 

 (apicem versus intus valde pectinatwm) supra producto. 



192. Pecteropus rostratus, Woll. (Tab. IV. fig. 9.) 



P. antice acuminatus, pubescens subnitidus subviridescenti- vel subcuprescenti-aeneus, capite pro- 

 thoraceque creberrime tuberculato-asperatis, elytris profunde puuctato-rugulosis, antennarum 

 basi pedibusque rufo-testaceis, illis iu marc longioribus. 

 Var. a., plerumque subviridescenti-seneus antice valde acuminatus, prothorace antice angustato, 



pedibus omnino pallidis. (Ins. Partus Sanctus.) 

 Var. fi. plerumque subcuprescenti-seneus antice acuminatus, prothorace antice minus angustato, 

 tibiis intcrdum vix obscui-ioribus. (Ins. Deserta Grandis.) 

 Long. Corp. lin. 2-21. 



Habitat in floribus Portus Sancti et Desertse Grandis, tempore vemali, non infrequens : var. a., sola in 

 Portu Sancto solo occurrit ; scd var. /3. ad Desertam Grandcm, et tantum uisi fallor ad banc 

 insulam, pcrtinet, qua Maio c.xeunte a.d. 1850 plurima specimina inveni. 



P. elongate-ovate (being more acuminated anteriorly than either of the preceding species) ; thickly 

 pubescent and very slightly shining ; fencous, with either a slightly greenish or a slightly coppery 

 tinge. Head and prothorax very thickly and coarsely granidated : i]i& former ovate (being longer 

 and narrower than in either of the other species), exceedingly depressed,, and with scarcely any 

 indications of frontal impressions ; with the eyes hardly at all prominent : the latter widest cither 

 about or a little behind the middle. Elytra coarsely rugulosc, and more distinctly punctui'cd 

 than in either of the previous species ; rather expanded behind. Anteniue at base, and the legs 

 rufo-testaceous ; the former very distinctly longer in the males than in the females. 



Var. a. generally of a greenish-brassy tinge, and much acuminated anteriorly, — the prothorax being 

 usually widest a little behind the middle and considerably narrowed in front; the legs entirely 

 pale. (The state peculiar to Porto Santo.) 



Var. /3. usually of a more coppery tinge, and less acuminated auterioi'ly, — the prothorax being 

 generally widest about the middle and but very slightly narrowed in front ; the tibia: generally 

 a little dusky. (The form on the Dezcrta Grande.) 



A very interesting Pecteropus, and one which has been liitherto only detected, 

 so far as I am aware, in Porto Santo and on the Dezcrta Grande. It may be 

 immediately recognised from the P. Jluderensls and rtigosus, th'st, by the strtictiu'e 

 of the second joint of its male fore feet (the peculiarities in the distribution of the 

 inner setoe of which have been ah'eady pointed out) ; and, secondly, by its some- 

 what larger and anteriorly tapering outline, — its narrow, ovate and exceedingly
