and flattened at the tip in,the @. Prothorax transverse, gradually narrowed forwards, strongly 
constricted in front, the sides slightly rounded anteriorly and at the extreme base; closely, coarsely 
punctate, except along the smooth median line, Elytra moderately long, gradually narrowing from the 
rounded humeri, depressed along the suture; with feebly punctured deep stri, the interstices flat, 
coarsely uniseriate-punctate, 2 and 3 closely, irregularly punctate, and 3 widened, at the base, 7-9 
costate at the apex. Pygidium densely punctate, large and somewhat tumid in the 6, flattened, vertical, 
and smaller in the 9. Beneath somewhat densely punctate; first ventral segment slightly depressed 
down the middle in the ¢. Prosternal sulcus straight, rather shallow. Femora rather sharply dentate. 
Length 43-53, breadth 2,4,-25 millim. (d @.) 
Hab. Mexico, Cuernavaca in Morelos (H. H. Snith; Wickham; Deam, U.S. Nat. 
Mus.). 
A pair found by Mr. C. C. Deam, a female by Mr. Wickham, and a male by 
Mr. H. H. Smith. More elongate than P. senescens, the elytra depressed along the 
suture and almost bare (the basal spot excepted), the femora dentate. ‘This last- 
mentioned character separates P. dentipes from P. discreta and its allies,

Morelia (Hége), Acaguizotla in Guerrero (If. H. Smith), Cuernavaca (Barrett, in U.S. 
Nat. Mus.). 
Apparently a common insect in Western Mexico, and recognizable amongst the 
allied forms by its large size, immaculate elytra, and feebly dentate femora. I have 
seen the types of Boheman and Solari, and also the specimen in the Sturm collection 
The original type of B. tibialis + has 
the prothorax a little more transverse and more coarsely punctured than usual, and 
the ferruginous colour of the tibize in this insect is of course due to immaturity. The 
first ventral segment is slightly hollowed down the middle in the male. ‘The elytral

subsequently described in Schénherr’s work 
interstices are less distinctly costate at the apex than in P. undulata and its allies.

Hab. Mexico, Atoyac, Teapa (H. H. Smith); Guatemaza, Zapote, Duefias (Champion) ; 
Costa Rica!, Escazu, Higuito (Biolley), Caché (Rogers). 
A small, oblong-ovate, black form, with a coarsely punctured prothorax and a row 
of rather coarse transverse impressions along each elytral interstice (the third neither 
widened nor aibo-squamose at the base), the prosternal sulcus straight and deep, the 
anterior femora with a short tooth, the rostrum elongated and smoother in the female 
than in the male. Sent in numbers from Higuito.
