3. Nemognatha hiimaculata, witli 

 2 pages of text, marked I'l. Ill (pi. 7 

 in 1S24). 



4. Notox/is iiioiiodoii, the lower 

 fig., and jY. bicolor, with 4 pages of 

 text, marked PI. IV {Anthicus bicolor 

 and A. ?noiiodon, pi. 10, in 1S24). 



5. Bcrytus spinosits. with 3 pages 

 of text, marked PI. V (pi. 14. in 1S24). 



6. Cicindela formosa. and C. de- 

 cemnotata, with 4 pages of text, marked 

 PL VI, and followed by an index of the 

 8 species figured (pi. 18 in 1S24). 



The text in 1S24 is tliroughout difler- 

 ent from the text in 1817. mostly short- 

 ened,, but scarcely ditVerent for the 

 descriptive part of the species. The 

 coloration of the plates is mure caretiil 

 than in 1S24 and better than in Le- 

 Conte's edition. 



The Memoirs of the Philadelphia 

 society for promoting agricultm^e. \ol. 

 4, Philadelphia, iSiS, 8°, contain two 

 letters of Thomas Say. which are not 

 mentioned in Doubleday's List of Thom- 

 as .Sav's works, nor in LeConte's edition, 

 nor quoted by Th. \V. Harris. Dr. 

 Asa Fitch states that lie has never seen 

 this rare book. The volumes were pre- 

 sented to the Library of Harvard college 

 in 1849, after Harris had done his work. 

 He knew it, but as it contains notliing 

 of importance it is not quoted i)y Harris, 

 though in one volnme a letter to him is 

 found on the cover. 



1. A letter, Sept. 28. 1817, to Hon. 

 R. Peters, by Thomas .Say, p. 234-226. 

 containing remarks on tiie Hessian H\'. 

 on the locust and on corn gruhs. 



2. A letter, p. 236-237, to the same. 

 b\' ThoniMs Sa\'. containing remarks on 



the Hessian fly. on Tinea oraiiclla. 

 and on cut worms. 



[The references, to these two arliiles, which 

 were written out several years since, are

.Soi^ND-l'HonUCING ORG.'WS IN Axo- 

 MAL.V. An'TIIONOMIS, ANP orilKR 



coLEOl>TER.\. — There is a stridulating 

 organ in Anoniala, situated on tiie meta- 

 thorax and clvtra, in the same position as 

 described by me in Polyphylla (Psyche. 

 V. 2. p. 278). Its location is the same as 

 that of the elytral organ described by 

 Dr. LeConte (Class, col. X. .\.) in 

 Trox and Ligyriis, but Dr. LeConle 

 failed to notice that the melathorax in 

 those genera has on its ascending portion 

 (beneath a ridge in Trox) a corresi)on- 

 ding pearl\ space, just as it has in 

 Polvplivlla; this is in addition to the 

 organ on the first ventral, corresponding 

 to the third dorsal, segment, in Trox. 

 described by Dr. LeConte. My finding 

 these organs in mclolontliini and rntcl- 

 iiii is merelv accidental : why does not 

 some coleopterist study them microsco- 

 picalh in all our genera of scaralmei- 

 dac? Tlie same organs are present in 

 L/'inoni/is and other clateridac. and 

 there is, besides, a surface on the ascen- 

 ding portion ol the first ventral segment, 

 as in Trox. wiiich. as in 'Trox. corres- 

 ponds to a second surface on the elytra. 

 I find stridulating organs als> in An- 

 thonomiis. of the citrciil/onidae. situateil 

 as in Aiiiunala .
