PSYCHE. 



[October iS<)6. 



207, Geotriipes splendidus Fab. 

 This very common beetle has been 

 seen on the wing on numerous occa- 

 sions in March, and a pair was found 

 in copulation beneath a log on Dec. 

 20th. They usually mate in May. 



208, Ti-ox aequalis Say. The only 

 one of the nine species known to occur 

 in the county which has been found in 

 winter. Once, Dec. 12, beneath rail 

 in fence corner. 



309, Valgus canaliciilatiis Fab. 



210, V. squainiger Beauv. Both 

 have been taken on several occasions 

 in winter, notably on Dec. 10, 1S93, 

 when they were found gregarious in 

 numbers beneath a half hollow decay- 

 ing chunk which was filled with dry 

 dirt and situated in an upland thicket. 

 A single specimen of canalrcnlatus 

 taken at that time is unique in having 

 the tergita of the terminal ring of the 

 abdomen prolonged into a sharp spine, 

 3 mm. in length. Mr. H. F. Wick- 

 ham mentions in a private letter the 

 finding of an example of the same 

 species in Michigan, which possesses 

 a similar abdominal projection. 



Chryso.melidae. 



One hundred and nine species of 

 this family have been collected in the 

 county. Of these, mature specimens 

 of but twenty-six have been taken in 

 the winter months. 



211, jMyochrous dent i coll is Say. 

 Represented in my collection by a 

 single specimen, taken Feb. 28, from 

 beneath a chunk in the river terrace 

 woods. 



212, Metachrovia angiistiila Cr. 

 Once in winter, Feb. 14, from be- 

 tween mullein leaves. Common in 

 June on the flowers of Cornus and 



Ceanothus. 



213, Doryp/iora clivicollis Kirbv. 

 Uncommon at any time. Once, Jan. 

 5, from beneath mullein leaves. Sev- 

 eral times, single specimens in March. 

 On milkweed flowers in June. 



214, D. lO-lineata Say. Much less 

 common than 20 years ago. Usually 

 hibernates in the ground at a depth of 

 iS to 20 inches, but sometimes beneath 

 logs, rubbish, etc. On the wing in 

 early spring. 



215, Chrysoinela stitnralis Fab. 

 Dec. lo. 



216, C. similis Rog. Feb. 21. 



217, C. praecelsis Rog. These 

 three winter sparingly beneath chunks 

 near the borders of sandy cultixated 

 fields and along the old canal. Sutura- 

 lis is rare, the others frequent. Three 

 additional species, elegans Oliv., mul- 

 tipiinctatits and auripennis Say, have 

 been taken in the county, the first and 

 last on dates (Mar. 14 and Nov. 21) 

 which lead me to infer that they also 

 hibernate as imagoes. 



21S, Ceroto?>ia cami/iea Fdh. Rare. 

 Three only from county. One, Feb. 

 21, beneath log in lowland woods. 



219, Diabrotica vittata Fab. On 

 numerous occasions in winter from be- 

 neath logs and rubbish in dry sandy 

 places, especially along the borders of 

 fields in which melons and cucumbers 

 had been cultivated. 



220, Galeruca nottilata Fab. Be-
