Mr. Riley has given us, in his final report on the insects of 

 Missouri, the complete life-history and full notes on the ravages 

 and general habits of Nematus ventricosus ; a nearly complete 

 account of Lopliyrus lecontei ; has supplied the desiderata in 

 the history of L. abbot ii ; and has added, from his earlier pub- 

 lications and those of Walsh, histories of Pristiphora grossulariae 

 and Emphytus maculatus — all Tenthredinidae. He has also 

 given a full account of Eufitchia ribearia, has added the most 

 important parts of the history of the army-M^orm, and has fur- 

 nished the liistory of an alHed form, Leucaiiia albilinea. Notes 

 on the Colorado potato-beetle are also given, but these are taken 

 from his work on potato-pests published the previous year. Per- 

 haps the most interesting parts of the report are the account of 

 the second species of Leucania (X. albilinea)^ which confines its 

 attacks principally to heads of wheat, and the discovery of the 

 mode and place of oviposition of both the species of Leucania. 



Dr. Packard's account of injurious insects in the west, while 

 la rgely relating to the destructive locust, includes histories of 

 over one hundred other insects. These histories have been 

 collated, in large measure, from his earlier publications and 

 those of others. In addition to what was already known, he 

 gives full notes upon the red-legged locust (^Caloptenus femur- 

 rubruTn)^ Donaciapt'oxitna, the northern army-worm (^HeliopJiila 

 unipuncta), the cabbage web-moth (^Plutella xylostella)^ 

 G-asfropacha californica, PJiryganidea californica, the two latter 

 contributed by Mr. H. Edwards, and Pieris rapae ; as well as 

 brief notes on Oedipoda p)^^lucida, Acridium americanum, 

 BUss2is leucopterus, BrucJms fabae, Eurytoma hordei, Cecido- 

 myia destructor^ Aletia argillacea, Clisiocampa americana^ 

 Aegeria cucurbitae and Nematus ventricosus ; figures of the 

 early stages of most of these are given, with maps showing the 

 distribution of the Cecidomyia, Blissus, Heliophila, Aletia and 

 Eurytoma, as well as of Cecidomyia tritici and Heliothis armi- 

 gera ; he also gives some new accounts of the journeyings of 

 the notorious Colorado potato-beetle and original figures of the 

 early stages of a Harpalus, of Pleotomus pallens, of Pryocoetes 

 affaber and of Tomicus pint.
