P. margaritaceas, Er., inter alia has the basal joint of the antennal 

 funicle louger in proportion to the 2nd joint. P. angustatus, 

 Fahrs., inter alia is very distinctively and differently marked with 

 silvery scales. P. pusio, Sch., is a much smaller insect, variegated 

 ■with black, white and ferruginous markings. P. sparsus, Germ., 

 is only doubtfully distinct from P. mactdosus, Fahrs., which inter 

 alia is very different in respect of its rostrum. 

 Victoria. 



Pelororhinus crassus, sp.nov. 



Minus elongatus ; piceus plus minusve rufescens, supra squamis 

 argeiiteo-niveis et nonnullis obscure griseis maculatim 

 vestitus, corpore subtus fere toto albido-squamoso ; prothorace 

 quam latiori vix longiori, lobis ocularibus nullis ; elytris 

 punctulato-striatis ; rostro supra longitudinaliter fortiter vix 

 sequaliter arcuato, minus brevi ; antennarum funiculi articulo 

 basali quam 2**^ fere sesqui longiori; oculis quam P. argentosi, 

 Gyll., pauUo minoribus. [Long. 6-7, lat. 2-2| lines. 



The scale-pattern on the head and prothorax is almost as in 

 P.argentosus ; on the elytra it is very different, having no tendency 

 to run in vittse ; it may be best described by reganling the silvery- 

 white scales as forming the ground ; this ground is interrupted by 

 the rows of denuded spots or granules usual in the genus, and 

 which are less closely placed in this species than in most others ; 

 there are also two obscure fascia-like spots on each elytron (one a 

 little in front of, the oihey a little behind, the middle) on which 

 the scales are much less close than on the rest of the surface and 

 are of a pale fuscous tone of colour ; the whole of these markings, 

 however, are clearly defined only in very fresh specimens. The 

 most distinctive character seems to consist in the form of the 

 rostrum. 



Rhinaria caliginosa, Pasc. 



There does not seem to be much doubt that this species is either 

 R. rugosa, Boisd., or B. excavata, Boisd., and it appears to me 

 very probable that they are two names for one species. Between 

 Boisduval's descriptions of the two I lind no difference excejjt that
