4 ( J0 NOTES ON LACHNOSTERNA. 





In tbe afternoon of this day I picked up the first specimen of L.fra- 

 terna v , on the road. 



May 14.— Cold and rainy. No beetles flying and none came to light. 



May i,-).— The same conditions prevailed. 



May Hi. — Chilly, yet close. No rain. Mr. Roberts and myself went 

 down into Rock Creek Valley, but neither saw nor heard a specimeu. 

 The blackberries are just beginning to bloom but attracted nothiug. 

 Returning, we found on the pear trees L. arcuata, 1 2,2 9 . 



May 17. — On the Department of Agriculture grounds, the party con- 

 sisting of Messrs. Schwarz, Pergande, Roberts, and myself. The even- 

 ing was cool and threatening, but it did not rain. 



The result of the combined collections was : L. arcuata, 307 8 , 161 9 ; 

 /,. inversa, 230 8 , 107 9 ; L. hirticula, 57 8 , 43 9 ; L. micans, 3 $ ; L. 

 fraterna, 2 8 ; L. hornii, 19; in all, 974 specimens. Mr. Roberts kindly 

 assisted me in sorting this catch. Oaks and hickorys were beaten, the 

 oaks giving the fraterna and hornii. The fraterna here taken, by the 

 bye, is the form determined as forsteri by Dr. Horn, and to this form 

 his paper led me in the determination. After-study convinced me that 

 the specimens taken ou the Agricultural grounds were really of a dis- 

 tinct species. As I did not make this discovery until after the col- 

 lecting season was over, I can not say exactly what specimens are fra- 

 terna and what the new species as they are referred to in my notes. I 

 .shall therefore make no effort to distinguish here, but will call every 

 thing fraterna that then seemed to be such. 



The time spent was about one and one-half hours, and the capacity 

 of the bottles determined the cessation of the collection, 



May 18. — Lanier Heights with Mr. Roberts. The oaks at the foot of 

 the hill were visited and gave: L. fraterna, 2 S ; L. micans, 3 8. On 

 privet and pear we took: L. arcuata, 7 8 , 7 9 ; L. hirticula, 3 8 . 



May 20. — Lanier Heights with Mr. Roberts. The oaks at the foot of 

 the hill were again visited; the night was damp, chilly, and moonlit. 

 L. arcuata, 3 8 , 1 9 ; L. hirticula, 13 $ , 4 9 ; L. tristis, 3 8 • L. aftinis, 

 4,5.52; L. inversa, 2 8,2 9 . 



The affinis with one exception were from the same tree ; the others 

 close by, gave principally hirticula; inversa scattered ; the tristis were 

 on the same tree with affinis. 



The ground was full of hirticula, buzzing in every direction. No 

 more were taken by us because they flew to the high branches, which 

 were not easily reached. Nothiug was found either on pear or on 

 privet. 



May 22. — At the Department of Agriculture, Messrs. Schwarz, Per- 

 gande, Alwood, and myself. Night cool and cloudy: oak, hickory, and 

 hazel were beaten and proved almost equally productive. L. tristis, 

 1 9 ; L. hornii, 18; Jj. fraterna, 3 8 ; L. hirticula, 01 $ , 42 9 ; L. ar- 

 cuata, 116 <3, 194 9; L. inversa, 137 8, 115 9 ; in all, 733 specimens. 

 The principal flight seems over. It is noteworthy that the character
