NOTES OX THE WINTER INSECT FAUNA OF VIGO COUNTY, 



INDIANA.— VI. 



BY W. S. BLATCHI.EV, INDIANAPOLIS, INDIANA. 



COLEOPTERA (Cont.). 



CoCCrNELLIDAE. 



Twentv-one species of these interest- 

 ing and lieneficial beetles were taken 

 in the county. Thirteen of these 

 were found to hibernate as imagoes, 

 while one other, Hippodaiiiia gla- 

 cialis Fab., was taken on two occa- 

 sions in the latter part of March, 

 so that it probably also winters 

 in the mature stage. 



125, Megilla maciilata DeG. By 

 far the most abundant member of the 

 family in Indiana. During October 

 it congregates beneath rubbish and 

 logs. On several occasions I have 

 found them in midwinter bv thousands, 

 huddled together beneath piles of the 

 stems of the larger ragweed {Ambrosia 

 trifida L.) in the low bottom lands 

 of the Wabash River. It also hil)er- 

 nates singly beneath mullein leaves. 



126, Hi'ppodamia converge)! s Guei'. 



127, H. ij-piinctata Linn. 

 I 28, H. parenthesis Say. 



129. Coccinella g-ttotata Hbst. 



The above four are frequent in 

 winter beneath mullein leaves and 

 chunks along the borders of sandy, 

 upland, cultivated fields. 



130, Coccinella sanguinea Linn. 

 Once, Feb. 23, beneath mullein. 



131, Adalia bipiinctata Linn. 

 Once, Jan. i. beneath the bark of an 

 ash snag. 



132, Ckilocoriis bivulnerns Muls. 

 Several times, singlv, beneath chunks 

 in upland sandy woods. Flies on the 

 first warm days of spring, and is then 

 frequently found resting on the sunny 

 side of rails or posts of fences. 



133, Hvperaspis dissol/ita Cr. Dec. 

 10. 



134, //. iindiilata Say. Jan. 7. 



135, Scymmts sp? Jan. 21. 



136, Scvmniis sp ? Jan. 6. 



137, 6'. harmorrlioiis Lee. Dec. 23. 

 Each of the above, once eacii in 



winter, date given, from beneath mul- 

 lein or chunks in upland fields. 



Endo.myciiidae. 



Five of the eight species known to 

 occur in the county have been taken 

 in winter, as follows: 



13S, L\coperdina ferr/ig/nea Lee. 

 Dec. 28.' 



139, Apliorista vittata Fab. Jan. 



140, Mycetitia perpiilclira Newm. 

 Dec. 24.
