sylvania." Mr. Klages finds this species on hickory trees only, but 

 Mr. Schwarz tells me that he has taken both it and gibbosa on 

 hickory and on various other trees as well 



It gives me great pleasure to dedicate the species to Mr. Klages, 

 to whom I am indebted for a series of specimens as well as for many 

 courtesies extended at the Carnegie Museum and at his home. 



3. T. gibbosa Say. — Oblong, moderately robust, densely clothed with gray- 

 ish white recumbent hairs, except the posterior median portions of the prothorax, 

 and a broad discal posteriorly rounded basal area on the elytra. Antennal club 

 subequal in length to all the preceding joints, the intermediate joints mutually 

 similar and all a little longer than wide. Prothorax evidently narrower than 

 the elytra, sides a little arcuate and convergent posteriorly, hind angles rounded ; 

 disk strongly gibbons, surface throughout rather densely granulate, each granule 

 bearing a long fine erect hair, the vestiture otherwise dense and subrecumbent, 

 except as above noted ; the summit of the gibbosity with a divided tuft of brown 

 and fulvous hairs, and anterior to these two smaller similar tufts. Elytra with 

 coarse punctures arranged in somewhat irregular rows, and numerous small 

 rounded granules which are more conspicuous at base; vestiture consisting of 

 dense recumbent whitish gray hairs intermixed throughout with long tine erect 

 hairs. The whitish recumbent hairs are. however, nearly lacking in a large 

 basal area which contrasts strongly with the adjacent densely clothed portions, 

 and are also sparser in the apical fourth. Within the dark basal area there are 

 on each elytron two elongate lines or tufts of dark brown and fulvous hairs, one 

 sutural the other parallel to and exterior to the first. At the posterior fourth 

 there is on each elytron a transversely arcuate series of four smaller tufts. Under 

 surface and legs as described of eristata. Length 5-6.7 mm. 



Widely distributed throughout the Atlantic region and in the 

 Mississippi Valley. The following localities are represented in the 

 material at hand. Massachusetts, New York, Pennsylvania, Ohio, 

 Florida, Canada, Michigan, Indiana, Iowa, Missouri, Louisiana, 

 Kansas. 



Dr. Hamilton records the occurrence of this species on elm sprouts. 



4. T. beyeri n. sp. — Oblong, brown, twice as long as wide; vestiture gray- 

 ish, with the usual darker erect hairs, moderately dense, but not concealing the 

 surface color of the elytra, the latter with a suhmedian rounded suhdenuded 

 area. Head sparsely punctate and granulate. Antennal club distinctly longer 

 than the preceding joints in both sexes; joints 4-8 about as wide as long, the 

 ninth more parallel and equal to the five preceding in the male, more trian- 

 gular and a little shorter in the female. Prothorax narrower than the elytra, 

 the sides straight or feebly arcuate and moderately converging behind ; hind 

 angles rounded. Surface gran ulose, summit of gibbosity with four approximate 

 spots of brownish black hair, which is, however, scarcely longer or tufted. Ely- 

 tra coarsely confusedly punctate, scarcely at all granulate, each with two tufts of 

 blackish hair within and close to the front margin of the denuded area, and a
