40 RHYNCHOPHORA. 
in a long, dentiform process ; deeply punctate-striate, the punctures of the strize becoming very coarse 
towards the sides, the interstices feebly convex. Second ventral segment with two indistinct prominences. 
Legs short. 
Length 33, breadth 12 millim. ( 2.) 
Hab. Mexico, Acapulco (fHége). 
One specimen. ‘This insect, at first sight, was supposed by me to be the female of 
C. armatus, but this cannot be the case: the eyes are more approximate in front, the 
seriate punctures of the elytra are much coarser towards the sides, the apices are 
dentiform, the vestiture is uniformly whitish beneath, the blackish rhomboidal patch 
on the elytra is much smaller, &c. 
8. Cylindrocopturus albonotatus, sp.n. (Tab. III. figg. 11.) 
Elliptic, flattened above, nigro-piceous; the upper surface variegated with a dense clothing of oval and 
rounded, overlapping, fulvous, white, and dark brown scales, the seriate elytral punctures each with a 
narrow scale: the head fulvous; the prothorax fulvous, with a large subquadrate patch on each side 
behind, extending obliquely inwards anteriorly, and a narrow, abbreviated, median vitta, white; the 
elytra with a spot at the shoulder, another near the suture below the base, a sinuous, interrupted, post- 
median fascia (extending forwards along the suture), and the apex, white, and a short transverse fascia 
on the disc below the base (in a line with the first white spot) fulvous; the vestiture of the under surface 
and legs white, the femora faintly fusco-annulate. Eyes rather narrowly separated, the intra-ocular space 
widening above and beneath. Rostrum rugulose and feebly carinate at the base. Prothorax transverse, 
constricted and narrowed in front, the sides parallel behind; densely punctate. Llytra a little wider 
than the prothorax, rounded at the sides, the apices raised and separately, angularly produced; deeply 
punctate-striate, the interstices narrow, raised, about as wide as the striz. Legs short. 
Length 33-32, breadth 13 millim. 
Hiab. Mexico, Toxpam in Vera Cruz (Sallé), Cordova (fége). 
Two specimens, one of them in perfect condition. ‘The short, transverse (not 
oblique), fulvous fascia on the disc of the elytra below the base, the somewhat 
tricruciate white sutural stripe, and the subquadrate large white patch on each side of 
the prothorax at the base, and the white under surface, distinguish C. albonotatus. 
The scales are smaller than in C. tmbricatus.

Hab. Nortu America, Colorado®, Texas!, and Arizona*.—Mexico, Northern 
Sonora (Morrison). 
Sent to us by Morrison as from Sonora, and by Wickham from Utah, Colorado, and 
Texas (Brownsville). ‘The white spots on the prothorax are sometimes coalescent into 
three vitte; the two curved series of white spots on the elytra vary somewhat in 
extent, the intervening portion of the suture being bordered with white.
