INSECTA MADERENSIA. • 267 



its legs and antennse, particularly the latter, are less robust, — the former of which 

 moreover have their tibite and tarsi paler than the femora, whilst the terminal 

 joint of the latter is more elongated and less apically obtuse than in the P. albo- 

 jnctiis. The only specimen which I have seen was captured by myself in the 

 vicinity of Funchal (I believe in the Ribeiro de Santa Luzia) during the spring 

 of 1849. 



205. Ptinus albopictus, Woll. (Tab. V. fig. 4.) 



P. fusco- (rarius nigro-) piceus squamis cinereis variegatus, elytris subrotundatis dilutioribus punc- 

 tatis (punctis minoribus crebris), fasciis duabus (sc. basali, vel omnino diffusa vel obsoletissima ; 

 et subpostica, plus minusve distincta) per suturam interruptis albidis ornatis, antennis pedibusque 

 subelongatis pallidioribus sed vix squamosis. 



Var. a. nigro-piceus parce cinereo-adspersus, elytris rufescenti-brunneis, fascia basali obsoleta sed 

 subpostica distincta, pedibus obscuris. Long. 1-1^ lin. (In Madera propi-id stains typicus.) 



Var. j3. fusco-piceus cinereo-variegatus, elytris paulo dilutioribus, fascia basali diffusa sed sub- 

 postica distincta, pedibus rufo-testaceis. Long. |-1 lin. (In Desertd Grandi status typicus.) 



Var. y. fusco-piceus vel fusco-ferrugineus dense cinereo-variegatus, elytris paulo dilutioribus, fasciis 

 omnino diffusis confluentibus, pedibus plerumque rufo-testaceis. Long. 'i-\ lin. (In Desertd 

 Ch-andi status aberrans, sed in Porlu Sancto typicus.) (Tab. V. fig. 4.) 



Var. S. fusco-ferrugineus dense cinereo-variegatus, elytris dilutioribus (interdum etiam subflaves- 

 centibus), fasciis diffusis sed subposticS, ssepius leviter distincta, pedibus rufo-testaceis vel etiam 

 testaceis. Long, vix i-§ lin. (In Desertd Boreali.) 

 Long. Corp. lin. vix ^-1^. 



Habitat in insulis Maderensibus, usque ad 3000' s. m. ascendens : ror. a. ad Maderam propriam 

 solam (nisi fallor) pertinet : var. /3. Desertse Grandi propria est, qua. caules Silybi Mariani, Grtn. 

 ( = Cardui benedicti, antiquorum) destruit : var. y. in Portu Sancto prsedominat, lichenes in 

 rupium fissuris crescentes colens : var. S. in DesertS, Boreali, et nusquam nisi illic, occurrit, qua 

 Junio ineunte a.d. 1850 copiosissime observavi. 



P. brownish- (rarely dark) piceous, and more or less densely variegated with cinereous scales. Pro- 

 thorax rather convex, a little longer than in the P. pilula, and very slightly rounded at the sides. 

 Elytra subrotundate, — being, throughout all the varieties, less decidedly spherical than those of 

 the P. pilula (nevertheless not ovate, since they are widest about the middle) ; more or less diluted, 

 or rufescent, in colouring ; punctured (the punctures being small, and close together ; and with- 

 out any tendency to be disposed in rows) ; and with more or less obscurely defined paler scales 

 in the usual positions, to represent the fascise, — the basal one of which however is usually im- 

 mensely diffused, so as to lose its fascia-form character, and often entirely confluent with the 

 posterior one (being only in rare instances evanescent) ; whilst the hinder one is generally better 

 defined (being seldom entirely suffused). Antennae and legs rather slender, more or less pale, 

 and almost free from scales ; the former nearly filiform, with their apical joint thick and ovate ; 

 the latter with their tarsi rather long, but not very broad. 

 Var. a. usually large, dark ])iceous, and only sparingly besprinkled with (rather small) cinereous
