The Ohio Naturalist. 
[Vol. II, No. 5 
color follows the third and fifth longitudinal veins to beyond the anterior 
cross-vein ; subhyaline spaces at apex of costal, base and apical fourth of 
marginal, apical third of submarginal and disk of first posterior cel Is ; posterior 
border hyaline ; femora and tibite yellowish, tarsi black. Abdomen without 
macrochaetae, 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, io mm., 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 very striking species, and it is with some hesitation 
that I locate it in Phorantlia. Its wide wings and general form 
suggest Alophora pulverea, 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, 
Cocpiillett in his valuable study of the Tachinidae, places fenestrata 
under Alophora. 
The January number of the American Naturalist 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, but 
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 Hall, February 3rd, 1902. 
The Club was called to order by President Mills and the min- 
utes of the previous meeting were read and approved. President 
Mills exhibited a copy of an As^ec 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 concludes that 
these plants should be placed among the Monocotyls rather than 
the Dieotyls. His paper will soon be published 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. W. Ditto and Mr. J. G. Sanders were elected to mem- 
bership. The Club then adjourned. F. J. Tylkr, Sec'y.
