HISTORY OF PASADENA. 



also in the air when necessary. This singular creature carries its eggs on 

 the shell- like wingcases over its back, says Jason Brown, where they some- 

 times appear thickly massed together, but always in orderly arrangement. 

 In this respect it is an approach toward the dorsological baby house style of 

 incubation, heretofore known only in the Surinam toad. 



Of a species of woolly spider I have seen both white and red varieties 

 in the mountains. 



Of course this is no place for a complete list of our native insects, for 

 they run up into thousands of species or varieties. Van Dyke says there 

 are at least ten different kinds of musquito here. I have only mentioned 

 a few of the more notable insects, because of their singularity, or because 

 as California curios they have become in some sense historic. The Pasa- 

 dena field of Entomology is a very large one, entirely unworked, and lies 

 open for some of our young naturalists to delve in and win fame. One of 

 the queer things in this line is, that bedbugs and cockroaches cannot live 

 here. Every season for the past twenty years bedbugs have been brought 

 to Pasadena in clothing, in bedding, in carpets, or in furniture, yet they 

 never live to propagate their species ; the same is true of cockroaches. The 

 reason for it still remains an unsolved problem for our young scientists to 

 wrestle with. 



As to books on California Entomology, a volume of 472 pages was pub- 

 lished by H. S. Crocker & Co., Sacramento, in 1883, entitled " Injurious 

 Insects of the Orchard, Vineyard," etc. It was prepared by Matthew 

 Cook, State Entomologist, was liberally illustrated, and stills holds the field 

 as the best California book of the kind yet produced.
