94 OTIORHYNCHID.^. 



[Horn. 



rately convex, finely punctured, densely scaly. Elytra regularly oval, 

 slightly acuminate posteriori}'-, sides regularly arcuate, base sub-truncate, 

 humeri slightly prominent anteriorly ; disc convex, feebly striate, striae 

 not closely punctured, intervals flat. The seventh slightly elevated at 

 humerus, surface verj^ densely scaly and with numerous verj^ short, semi- 

 erect, scale like hairs. Body beneath densely scaly, sparsely setose, legs 

 densely scaly, tibise sparsely pilose. Length .20-. 30 inch ; 5-7.5 mm. 



This species presents two varieties. 



var. tesselatus Say. Head and rostrum with earthy -brown scales, paler 

 around the eye and beneath. Thorax similar in color, with a narrow pale 

 line at the sides and a broader pale line on each side of a broad median 

 brownish space. Elytra earthy-brown, on each side of suture obscurely 

 variegated with paler mottlings and a small pale humeral line, and a narrow 

 space at the side of the tip. 



These specimens are found in Southern Illinois. 



var. pallidum. This variety is of somewhat larger size than the prece- 

 ding, the scales covering the surface are pale-greenish white, and with 

 barely perceptible darker spaces arranged \\^ a manner similar to the pre- 

 ceding variety. 



This variety occurs from Kansas to Texas. 



Both varieties have the lateral strise of the elytra more distinctly im- 

 pressed than those of the disc. 



A specimen of the latter variety was submitted to Mr. Pascoe, who was 

 of the opinion that it might be identical with " Sitona durius Germ." * 



A. Fulleri, u. sp. 



Form oblong oval, surface not densely clothed with dark -brown scales. 

 Head and rostrum longer than the tliorax, densely punctured, sparsely 

 scaly. Rostrum with feeble ridge on each side from the tip nearlj' to the 

 eyes. Thorax cylindrical, apex and base equal and truncate, very slightly 

 wider ihan long, sides feebly arcuate, a fine median line, disc moderately 

 convex, densely punctured, sparsely scaly. Elytra regularly oval, humeri 

 entirely obliterated, base sub-truncate, surface indistinctly striate, and with 

 rows of large, moderately closely placed punctures, intervals flat, not 

 densely scaly, and with very minute sub-erect hairs ; scales dark- 

 brown, a whitish or paler stripe beginning at the humerus, passing along 

 the lateral margin, ending in a short oblique f\iscia at the middle of the 

 elytra. Body beneath sparsely scaly. Legs with scale-like hairs. Ante- 



* Since the above was written tlie following note has been received from Mr. 

 H. Jeliel. 



•' Lipai-us tesselatus Say. It is a Naujmctus sensu Sch., so very allied to the 

 female of i\\ durius, Germ., from Brazil, that, should not the size be a th ird larger, 

 and the habitat so distant I would have regarded them as identical * * * , 

 For that group of y^aupacti I have created the genus Aomopactus." 



I am not aware that this genus suggested by Mr. Jekel has been described. 

 The remarks apply especially to the \ariety pallidus, Fulleri being more nearly 

 allied to ovulum Jek., from the Pampas, Mendoza.
