Horn.] CYPHIXI. 99 



long oval, slightly attenuate at apex ; base slightly broader than the thorax, 

 humeri obtuse. Intercoxal process moderately broad, rounded at tip. 

 Second segment longer than tiie two following united, and separated from 

 the first by a strongly arcuate suture. Articular surfaces of hind tibiae 

 open, slightly scaly. Claws connate. Anterior and middle tibite feebly 

 mucronate, not denticulate within. Surface scaly and hispid. 



The second joint of the funicle varies in the two species. It is slightly 

 longer thau the first in Unniatus and shorter in unicolor. Lacordaire is in 

 error in stating that the second joint is twice the length of the first in keniatus. 



Our species are two in number. 

 Second joint of funicle longer than the first ; elytra with four 



brown stripes taaniatus. 



Second joint of funicle shorter than the first ; elytra uni- 

 formly cinereous unicolor. 



A. tseniatus CTyll. Schonh. Gen. Cure, ii, p. 460 ; Saj^ Cure. N. A. p. 

 9, without description. 



Head and rostrum shorter than the thorax, densely scaly except at tip ; 

 scales pale brown above, cinereous at the sides and beneath, and Avith 

 sparsely placed short erect hairs. Thorax cylindrical, slightly narrowed in 

 front, sides feebly arcuate, base squarely, apex obliquely truncate, disc 

 moderately convex, not densely punctured, densely scaly ; scales pale 

 brown ; a pale line on each side of middle, sides and beneath cinereous. 

 Elytra oval, feebly striate, strife with moderately coarse verj' regularly 

 placed punctures, intervals feebly convex, surface densely clothed with cin- 

 ereous scales ; the second and fourth intervals with brownish scales, the 

 inner stripe longer, each interval with a row of very short whitish hairs.. 

 Body beneath and legs densely covered with cinereous scales ; tibise sparsely 

 hirsute. Length .20-.22 inch ; 5- 5.5 mm. 



This insect is very well-known to most collectors. The species has 

 usually been attributed to Saj^ but as the description of Gyllenhal is really 

 the first, it appears just to so accredit it. 



Occurs in the Middle and Southern States. 



A. unicolor, n. sp. 



Form elongate oval, densely covered with cinereous scales. Head and 

 rostrum as long as the thorax, moderately densely scaly. Thorax regularly 

 cylindrical, sides scarcely arcuate, apex obliquely, base squarely truncate, 

 disc sparsely punctured, surface densely ^scaly and with whitish erect hairs. 

 Elj'tra oblong oval, feeblj' striate, stride with large rather coarse punctures 

 very regularly placed, intervals feebly convex, densely scaly, each with a 

 single row of short, white, erect hairs. Body beneath, especially the abdo- 

 men sparsely scaly. Legs moderately scaly, tibite sparsely pilose. Length 

 .18 inch ; 4.5 mm. 



This species is rather narrower than tmniatus ; thorax more regularly 

 cylindrical, and with the erect hairs more distinctly" visible. It difiers es- 

 pecially in the structure of the funicle ; the second joint being but little 

 more than half the length of the first.
