1903I Book Notice. 14 



Americati Orthoptera, which includes every known reference to 

 each species up to the close of 1900. " A Descriptive Catalogue 

 of the Orthoptera known to occur in Indiana " treats in a 

 systematic manner of every species which has ever been found in 

 the state. Excellent tables enable the student easily to refer a 

 species, first to one of the two large sub-orders Saltatoria or 

 non-Saltatoria, and then to one of the seven families included 

 within these two sub-orders. The former, Saltatoria, embraces 

 the AcrididcB or true locusts, the Locustidce, or Long-horned 

 Grass-hoppers and Katydids, and the Gryllidce or Crickets. The 

 non-Saltatoria includes the Forficuhdm, or Earwigs, the Blatiidce, 

 or Cockroaches, the MantidcB and the PhasniidcB, or Stick Insects. 

 There are no less than 148 species described in this little book 

 in tull detail, and among these we find a large proportion of our 

 Canadian Orthoptera. Fourteen species of the number have been 

 described by Prof. Blatchley himself, and six of these are new 

 species described in this work for the first time. A short article 

 treats of " the Life Zones of Indiana," as illustrated by the 

 Orthoptera of the State, and the book concludes with a good 

 glossary of terms and a fyll index. The illustrations are 

 numerous and good. As a frontispiece, the beautiful coloured 

 plate of the pink variety of Amblycorphyra oblongijolia on a head 

 of Solidago sempervirens is used. This plate first appeared in 

 " Entomological News" for May, 1901. J. F. 



A WEED WORTH GROWING. 

 (Matricaria inodora, L.J 

 During the autumn of 1902 I had the good fortune to spend 

 a few weeks on that gem of the sea. Prince Edward Island, and 

 was particularly struck with the showy appearance of the above- 

 named Mayweed, which grows as a way-side weed in Summerside 

 and Charlottetown, as well as in many other parts of the Island 

 away from the towns. Thinking, from the size of the flowers, 

 that the plant might be worthy of a trial as a garden flower, I 

 gathered some of the seed and sowed it last spring. On my 

 return to Ottawa in the middle of August, I found a patch of 

 plants 3 feet across and 2 feet high, covered with large flowers, 

 several of them measuring over 2 inches across. From that time
