22 NATUEAL HISTOEY BULLETIN 



Legs -wanting, except a small portion of one of the hind pair which shows 

 no characters of importance. Length, exclusive of style, 3.40 mm. ; of anal 

 style, about .80 mm. Height, 1.55 mm. 



On account of its small size, this is referred to Mordellistena. 

 Compared with the fossil M. florissantensis, the present species 

 has a distinctly differentiated moderately long anal style and 

 relatively longer elytra. The name is given in memory of the 

 late John B. Smith, whose Synopsis of the Mordellidge is well and 

 favorably known. 



AuLETES Schonh. 



A. FLORISSANTENSIS n. sp. (Plate VI, Fig. 3.) Form rather slender and 

 elongate for this genus. Head narrower than the prothorax, eyes not dis- 

 tinctly definable but evidently small, antennae showing only a few of the 

 median joints which are rather slender. The cephalic punctuation is strong 

 and close, except on the occiput. Prothorax distorted by pressure, the sides 

 damaged so that their outline cannot be determined, punctuation per- 

 ceptibly less strong than that of the head but very close. The front coxae 

 are overlapped a little in the specimen, in life they were evidently con- 

 tiguous. Meso- and metasterna, with their side-pieces, strongly and closely 

 punctured, middle coxge contiguous. Elytra rather coarsely and closely 

 punctured, the discal punctures not in stria?, but showing some indication 

 of leaving a smooth longitudinal discal line and a stria is evident along the 

 outer margin. Abdominal segments subequal, punctured at sides, nearly 

 smooth along the middle. Legs slender and rather short for this family. 

 Length, from the base of the beak to the elytral apex, 4.75 mm. 



Unfortunately the beak is destroyed in my only specimen. The 

 insect is an undoubted Rhynchitid and is a much better exponent 

 of Auletes than the fossil A. wymani referred here by Scudder. 

 Recent species of this genus are found from Massachusetts to 

 British Columbia. 



Trypanorhynchus Scudd. 



T. MiNUTissiMUS n. sp. (Plate VI, Fig. 4.) Form moderately elongate. 

 Head full, very minutely sculptured in front, eye small and nearly circular, 

 behind it a fan-shaped figure of about thirteen fine rugae. Eostrum straight, 

 about equal in length to the dorsal line of the prothorax, striate and carin- 

 ate. Prothorax very little arched along the back, anterior side margin 

 about straight, surface closely and, for such a small insect, moderately 

 coarsely punctate. Elytra more finely sculptured than the prothorax, 

 punctures rounded, subseriate in arrangement at base but completely con- 

 fused apically. Underside of body much smoother than the upper, particu-
