The Triangle Spider in California. — 

 On Novembers, 1S9S, Professor O. P.Jenkins 

 of this University (Stanford) found a single 

 triangle spider {Hypiiotcs sp.) on its web in a 

 cedar tree near the Universitv. The web 

 was nine inches long and six inches wide at 

 its base. It had four radii and twenty-two 

 cross threads. At about the same time Dr. 

 Jenkins found a few other webs but was 

 unable to capture any more of the spiders. 

 The spider seems to be the familiar triangle 

 spider of the East, but differs in a number of 

 minor characters and rather markedly in size. 

 Until more specimens are obtained, however, 

 (and in the two years since finding the first 

 no others have been seen) the specific iden- 

 tity of this Hyptiotes cannot be certainly 

 determined. 



PROCEEDINGS OF THE CLUB. 



14 December, 1900. The 216th meeting 

 was held at 156 Brattle St., Mr. S. H. Scud- 

 der in the chair. 



Mr. W. L. W. Field showed a moth which 

 he had raised from a caterpillar mentioned in 

 tire Harris Correspondence and shown on pi. 

 3. fig. 2. The species is not ^-et determined. 



Mr. A. P. Morse showed specimens of 

 Dichromorfha viridis which he had taken at 

 Needham. It had not before been found in 

 eastern Massachusetts. 



Mr. S. H. Scudder read a note from Mr. 

 F. H. Sprague, announcing the capture of 

 the same species of grasshopper in a meadow 

 in .Milton, Mass., last September. Mr. Scud- 

 der also showed a specimen of Eiiftoieta 

 claniUa. a rare butterfly in New England, 

 captured at the border of Hartford, Conn., 

 by Mr. S. C. Carpenter; specimens of the 

 European Mantis religiosa, reared in Ithaca, 

 N. Y., by Mr. M. V. Slingerland, from eggs 

 received from Rochester, N. "Y., wliere the 

 insect has been in some way introduced, 

 and seems fairly domiciled; a pair of wing- 

 less Acridians, recently received from Mr. 

 T. D. A. Cockerell in New Mexico, where 

 they were found upon Larrea, the twigs of 

 which they closely resemble ; the species is 

 called Clematodes liirreae and not only 

 forms a new genus, but represents a new 

 group, allied to certain tropical groups and 

 especially the \'ilernae; and finally, a pair 

 of Cyfhoderris mons/rosa Uhl., the male one 

 of the types described from Oregon more 

 than 35 years ago, the female, hitherto un- 

 known, from Laggan, Alberta; the striking 

 difference between the sexes were pointed 

 out. 



Ml-. R. Hay ward showed a record which 

 he had kept during the past summer of the 

 notes of the Katydid with relation to tem- 

 perature (to appe:ir in I'>,VciiK'.
