238 RHYNCHOPHORA. 
3. Cyphus forreri, sp. n. (Tab. X. fig. 16, ¢.) 
Oblong, robust, black, densely clothed (a small space behind each eye excepted) with pale green, bluish-green, 
or greenish-cinereous scales, with minute, scattered, whitish, decumbent hairs intermixed ; the prothorax 
with two small spots on each side (those at the base sometimes obsolete), the elytra each with six or 
seven small spots (one above and one below the shoulder, one on the disc before the middle, and some- 
times another in a line with it on the eighth interstice, and from 2-4—the inner ones sometimes 
coalescent—at about one-third from the apex), and the intermediate and posterior femora each with a 
single spot, black. Head and rostrum sharply suleate and densely punctate, the rostrum hollowed at the 
apex; antenne rather stout, the scape reaching the middle of the eyes, the latter moderately convex, 
joint 2 of the funiculus twice as long as 3. Prothorax transverse, sinuate at the sides towards the base, 
campanulate in 9; densely, finely punctate, the disc transversely excavate in the middle posteriorly 
and with an abbreviated median sulcus. Elytra finely seriate-punctate, the ninth row of punctures sub- 
obsolete for some distance before the middle, the interstices flat and densely punctulate, the apices 
acuminate and dehiscent. Fifth ventral segment with an oblique impressed line on each side in front 
in 9. Legs short, the tarsi broad, the anterior tibia unarmed at the tip. 
Length 12-16, breadth 4-6 millim. (¢ ¢.) 
Hab. Mexico, Ventanas in Durango 2000 feet (Forrer), Alamos (Buchan-Hepburn). 
Seven specimens, one only in good condition. This is a form of C. modestus with 
the eyes less convex and the prothorax of the female campanulate. The spots on the 
elytra vary in number, and the one at the sides beyond the middle is often geminate. 
4. Cyphus lautus. (Tab. X. fig. 17, 3.) 
Tanymecus lautus, Lec. Proc. Acad. Phil. 1854, p. 85°. 
Cyphus lautus, Horn, Proc. Am. Phil. Soc. xv. p. 897; Pierce, Proc. U.S. Nat. Mus. xxxvii. 
p- 860°. 
Hab. North America, New Mexico 2, Arizona 23, Frontera, io Grande !.—Mexico, 
Northern Sonora (Morrison). 
Sent us in numbers by Morrison as from Sonora, these examples agreeing with 
others before me from Arizona, &c. Smaller than C. modestus, with the elytra more 
or less distinctly nigro-bifasciate on the disc (the fascize formed by oblong spots) and 
the punctures of the strize somewhat scattered and not covered by the vestiture, the 
prothorax with two small, obliquely placed, black spots on each side posteriorly, the 
head (as in C. modestus) with a small bare spot behind the eyes. C. placidus, Horn, 
also from Arizona, must be a very closely allied form, perhaps not really distinct from 
C. lautus. 
5. Cyphus quadripunctatus, sp. n. (Tab. X. fig. 18, 3.) 
Oblong, black, densely, uniformly clothed with small cinereous or cupreo-cinereous scales, intermixed with 
minute, white, adpressed hairs; the prothorax with two small spots at the base, the elytra with a spot at 
or below the shoulder, and sometimes a very small triangular scutellar patch also, and the intermediate 
and posterior femora each with a single spot, black. Head and rostrum sulcate, densely, finely punctate ; 
antenne rather stout, the scape reaching to the middle of the eyes, joint 2 of the funiculus nearly twice 
as long as 1. Prothorax transverse, subconical in 9, the sides subparallel behind and more rounded 
anteriorly in g, the base bisinuate; feebly sulcate, and densely, finely punctate, with coarser punctures
