genus (as far as they are known to me) in having elliptical ob- 

 lique eyes. Chiefly on account of this character, I have placed it 

 in Trypanorhynclius, near T. depratus from which it is at once 

 distinguishable by the relatively longer beak in T. ohliquus. 



AcALLES Schonh. 



A. EXHUMATUS n. sp. (Plate VII, Fig. 3.) The specimen is preserved in 

 such a position as to present chiefly a dorsal view. Form moderately elon- 

 gate and not very robust, recalling the recent A. iwrosus but with a differ- 

 ently shaped prothorax. Head not distinguishable. Prothorax broadest at 

 base, strongly narrowed anteriorly, the sides little if at all arcuate, surface 

 rather coarsely and very closely granulate, the granules rounded and with 

 a slight tendency to form longitudinal or radiating series, a distinct median 

 line present. Elytra with series of elevated rounded granules, effaced over 

 a great part of the surface but where present they are fairly regularly 

 spaced, separated by distances somewhat greater than their own diameters. 

 The courses of these series can be traced suflSciently well to indicate that 

 they were extensively confluent near the tip, the discal rows enclosed, as 

 usual in the Rhynchophora. Length, 6.25 mm. 



Some doubt must attach to this generic identification, which 

 is made chiefly upon facies. Nothing similar seems to have been 

 described by Dr. Scudder, the nearest approach to it being his 

 Rhysosternum ceternabile, in which the thoracic punctures form 

 distinct rugae. I assume that in my specimen the sculpture is in 

 reverse, and that the granules represent punctures. 



Baris Germ. 



B. FLORissANTENSis n. sp. (Plate VI, Figs. 6, 7, 8.) Form rather stout. 

 Head mostly concealed, except the rostrum which is short, only slightly 

 curved, and punctate near the base, eye elliptical and transverse. Pro- 

 thorax with close, deep, rounded punctuation, about uniform over the entire 

 disk. Elytra striate, the strife with distinctly elongate, well-impressed but 

 not very regularly spaced punctures, the interstitial areas broad, nearly flat, 

 with transverse alternating grooves and ridges, representing a further de- 

 velopment of the type of punctuation seen in the recent B. transversa. The 

 elytra overlap along the suture, confusing the arrangement of the striae, but 

 those of the disk are seen to be disposed very much as in B. transversa. 

 Legs, as far as shown, rather finely and somewhat rugosely punctured, only 

 the femora visible. Length, 4.75 mm. 



One specimen, showing obverse and reverse. This species is 

 readily distinguished from most of the other Florissant fossil 

 representatives of the genus by its size, in which respect it is
