color follows the third and fifth longitudinal veins to beyond the anterior 

 cross-vein ; subhj-aline spaces at apex of costal, base and apical fourth of 

 marginal , apical third of submarginal and disk of first posterior cells ; posterior 

 border hyaline ; femora and tibiae A-ellowish, tarsi black. Abdomen without 

 macrocluttte, but clothed with short, black hairs ; entire outer margin, 

 including the anterior half of the first segment and all of the small posterior 

 segment, pale brown, covered with white pollen, producing a pinkish shade ; 

 disk dark purple with a narrow, pollinose dorsal stripe ; venter uniform yel- 

 lowish. Length ; whole body, 10 nmi., wing 9 mm., width of wing at base, 

 5 mm. Habitat, Baldwin, Kansas. Two male specimens taken from flow- 

 ers of willow by Mr. J. C. Bridwell, for whom the species is named. 



This is a ver}' .striking species, and it is with some hesitation 

 that I locate it in Phorantha. Its wide wings and general form 

 stiggest Alophora ptilverea, but the bare sides of front bars it from 

 this genus. Bigot's description of fenestrata has been carefully 

 studied and the following differences noted : The coloring of the 

 wings is a conspicuous brown, which color includes the apex, and 

 the discal cell except the lighter margin of the fifth vein, the 

 femora are not fuscous above and the size is larger. Besides, 

 Coquillett in his valuable study of theTachinidae, places fenestrata 

 under Alophora. 



The Januar}' number of the America?! N'aturah'sf contains an 

 article by Prof. J. H. Comstock and Mr. Chujiro Kochi on " The 

 Skeleton of the Head of Insects," which deserves the closest 

 attention of students of the anatomy of insects. Heretofore our 

 knowledge of this subject has been in a chaotic condition, btit 

 this contribution certainly brings together what is known from 

 different sources, combines it with original studies and presents it 

 in such manner that .some final conclusions seem .safe. — H. O. 



MEETING OF THE BIOLOGICAL CLUB. 



Orton Haix, February 3rd, 1902. 



The Club was called to order by President Mills and the min- 

 utes of the previotis meeting were read and approved. President 

 Mills exhibited a copy of an Astec book which belongs to the series 

 copied by Mrs. Nuttall and published by Harvard University. 



Professor Cook gave the results of his investigations on the 

 embryology of the Nymphaeas and Castalias. He conchtdes that 

 these plants should be placed among the Monocotyls rather than 

 the Dicotyls. His paper will soon be publi.shed in the Torrey 

 Botanical Bulletin. 



A series of eggs, embryos, and young of the Salmon were 

 exhibited by Professor Landacre, who also gave an interesting 

 account of the annual migrations of this fish. 



Mr. T. \V. Ditto and Mr. J. G. Sanders were elected to ment- 

 ber.ship. The Club then adjourned. V. J. Tvi.i;r, Scc'y.
