CYLINDROCOPTURUS. 41 
10. Cylindrocopturus bifasciatus, sp. n. (Tab. III. fig. 13.) 
Oblong-elliptic, narrow, flattened above, black, the rostrum reddish; the upper surface variegated with a 
dense clothing of overlapping, oval and rounded, brown, ochreous, and whitish scales, the seriate elytral 
punctures each with a hair-like scale: the prothorax with a spot in the middle at the base and a sinuous 
vitta on each side white, the elytra each with a conspicuous spot at the base of the seventh interstice, a 
rather broad curved fascia at about the basal third, a short transverse fascia beyond the middle, a spot at 
the apex, and an oblique lateral patch opposite the first ventral segment, white or ochreous ; the under 
surface and legs with intermixed brownish and white scales. Eyes well-separated. Rostrum arcuate, 
rather coarsely punctate, carinate and rugulosely punctate at the base. Prothorax as wide as the elytra, 
not much broader than long, somewhat rounded at the sides, narrowed and constricted in front and 
slightly narrowed behind; densely punctate. Elytra subparallel at the base, the apices obtuse and slightly 
produced ; finely punctate-striate, the interstices feebly convex. Legs short. 
Length 3, breadth 1} millim. (¢.) 
Hab. Mexico, Durango City (Champion). 
One specimen. Differs from the other Mexican forms in having the prothorax and 
elytra almost equal in width. ‘The submarginal white vitte on the prothorax extend 
on to the base of the elytra; the arcuate fascia on the latter is ochreous, becoming 
white towards the suture. 
11. Cylindrocopturus elongatus, sp.n. (Tab. III. figg. 14, 144, 6, 3.) 
Elongate-elliptic, flattened above, black; the upper surface variegated with a dense clothing of coarse, rounded, 
overlapping, whitish, black (or fuscous), and fulvous scales, the blackish scales condensed on each elytron 
into a broad transverse or oblique fascia at about the middle of the disc and an irregular fascia between 
this and the apex, the seriate punctures each with a narrow scale ; the vestiture of the under surface and 
legs coarse, dense, and whitish, the femora more or less fusco-variegate along their outer half. Eyes 
very narrowly separated in front, the intra-ocular space widening upwards. Rostrum (<¢) arcuate, 
carinate, rugulose, and squamose to about the middle, and finely punctate thence to the tip, ( @ ) a little 
longer and smoother. Prothorax about as long as broad, gradually narrowing from near the base, feebly 
constricted in front; densely punctate. LElytra slightly wider than the prothorax, oblong-oval, the apices 
conjointly rounded and slightly produced; deeply punctate-striate, the interstices equally convex 
throughout, narrow, very little wider than the strix. Anterior cox with a conical prominence. 
Length 44-53, breadth 14-25), millim. (¢ 92.) 
Hab. Mexico, Acapulco, Chilpancingo, Iguala, Jalapa (H6ge). 
Six specimens. Recognizable by its elongate form, long prothorax, and equally 
convex elytral interstices, the latter not wider than the strie. The interrupted blackish 
fasciee of the elytra are sharply defined. 
12. Cylindrocopturus scaphiformis, sp.n. (Tab. III. fig. 15.) 
Oblong-elliptic, narrow, flattened above, nigro-piceous or piceous, the antenne, tibie, and tarsi obscure 
ferruginous; the upper surface variegated with a dense clothing of rounded, overlapping, fulvous, white, 
and brown scales, the seriate elytral punctures each with a narrow scale: the prothorax with a fulvous 
or whitish patch on each side at the base and apex, the elytra with a transverse fulvous patch on the 
disc below the base, and an irregular dark fascia below it, the suture, base, and some transverse or 
oblique marks towards the apex, whitish; the vestiture of the under surface in great part white, the 
flanks of the prothorax fulvous in one specimen, the legs also white, the femora mottled with fulvous 
above. Eyes narrowly separated, the intra-ocular space almost equal in width throughout. Rostrum
