FIELD AND FOREST, 



2. The marginal appendages ami edge 

 of the leaf are distinct from the remainder 



of the leaf and their motion is not simul- 

 taneous with that of the " clappers." 



3. The stellate hairs and glands are de- 

 veloped from the epidermis, but the sensi- 

 tive hairs from the subepidermal tissues. 



4. Stomata exist on both sides of the 

 leaf, but only on the under side of the 

 *' clappers." 



5. The structure and development of 

 the leaves suggest the hypothesis that the 

 movements of the " clappers " are due to 

 variable turgescense (absorption of sap) on 

 upper parenchymal surface alone. 



6 Sensitive hairs are the active organs 

 that convey the impulse of irritation direct 

 .to the sub-epidermal tissues. — Rot. Zei-

 nouncement of the death of D. H. Jacques,

The New England Farmer grows 

 facetious. It says : Entomologogists wili 

 be pleased to learn that that particularly 

 disgusting and valuable carnivorous beetle, 

 the Amblychila cylindriformis, whose very 

 existence has been doubted, is now found 

 in considerable quantities in Kansas.

F. Riley st Ues that on a recent trip Irom 

 Cuba to 15 >ston, w'ten fully 100 miles 

 irom land, east of the capes of Virginia, 

 his vessel wis board sd by several hundred 

 Colorado potato beetles. This was about 

 October 8th, and there wis a heavy blow 

 from the north-west. The insects were 

 evidently aided in their journey to this 

 distance from land by the wind. Some of 

 them when thrown overboard, spread their 

 wings before reaching the water, and flew 

 about easily, a (ew returning to the vessel.

Manuscript Notes from my Journal, 

 or Entomological Index to Vcri- 

 cultural Reports. By Tow >' end 



Glover, Washington, 1877. 



This is a quarto of 103 pages, in the 

 well-known chirography of the A ithor, 

 transferred to stone and printed by lithog- 

 raphy. In addition to a complete index 

 to all the reports issued by the Depart- 

 ment of Agriculture, it includes a list of 

 vegetable and animal substances injured 

 or destroyed by insects, etc. 



Such an index must be of great value to 

 entomologists desiring to use these rep )rts, 

 especially as references are given, with all 

 the insects named, to the author's unpub- 

 lished plate. s It is a matter of regret how- 

 ever, that but 60 copies have been printed, 

 and this small edition is already exhaus- 

 ted.
