Habits of Spinoliella zebrata (Cresson) (Hym.). 



On July 25, in the vicinity of the Bluebird Mine, in the mountains 

 of Boulder County, Colorado, I found a great number of bees swarm- 

 ing in the road. They were flying rapidly over the surface of the 

 ground, and frequently half a dozen or more would engage in a fight, 

 tumbling over each other in the dust, in a confused mass. On catching 

 a few, I found that they were all males, and to my great astonishment, 

 belonged to the species Spinoliella zebrata, which I had never seen alive 

 before. It is a very conspicuous bee, hardly to be overlooked, and its 

 local abundance in a region where it had never been observed during 

 ten years was astonishing. — T. D. A. Cockerell, Boulder, Colo. 



Some Muscoid Synonyms. 



The following synonymy is offered as a matter of record : — 



Clytiotnyia punctata Coquillett, 1895, Jn. N. Y. Ent. Soc. III. 52-53; 

 Oestrophasia punctata Coquillett, 1897, Rev. Tach. 71, equals 

 Ormia punctata R. D., 1830, Myod. 428. 



Oestrophasia setosa Coquillett, 1902, Proc. U. S. N. M. XXV, no, 

 equals Oestrophasia clausa B. B., 1889, Muse. Schiz. I. 145-146. 



Senotainia fasciata Coquillett, 1897, Rev. Tach. 81, equals Eumacrony- 

 chia elita Townsend, 1892, Trans. Am. Ent. Soc. XIX. 100. 



Paraphyto Coquillett, 1895, Jn. N". Y. Ent. Soc. Ill, 105, apparently 

 equals Wohlfartia Brauer & Bergenstamm, 1889, Muse. Schiz. I. 

 123. The holotype of P. chittendeni appears to be strictly con- 

 generic with the European W. meigenii Schiner. 



Polychaetoneura elyii Walton, 1914, Proc. Ent. Soc. Wash. XVI. 

 90-91, equals Thryptocera americana Townsend, 1892, Can. Ent. 

 XXIV. 69-70, equals Gymnophthalma Lioy, 1864. 



Neaera longicornis Coquillett, 1902, Proc. U. S. N. M. XXV. 106-107, 

 equals Clausicella usitata Coquillett, 1897, Rev. Tach. 56, equals 

 female Schizotachina convecta Walker, 1856, Dipt. Saund. 276. 



EuHALLiDAYA severtnii Walton, 1914, Proc. Ent. Soc. Wash. XVI. 

 130-132, equals Biomyia genalis Coquillett, 1897, Rev. Tach. 82-83. 

 The two specimens referred to under the name severinii are both 

 males. The female differs externally only in having the front, 

 and especially the face, broader, outside of the hypopygium. 



Tachinopsis Coquillett, 1897, Rev. Tach. 120, equals Plagiprospherysa 

 Townsend, 1892. 



Petia Coquillett, 1910, Proc. Ent. Soc. Wash. XII. 126-127, equals 

 Catharosia Rondani, 1868. The two genotypes are so nearly 

 identical in both structure and color that it will be difficult to define 

 their distinctness. 



It may also be mentioned that Thryptocera dunningii Coquillett, 1895, 

 Jn. N. Y. Ent. Soc. III. 54, referred to Hypostena in 1897, Rev. 

 Tach. 60, equals Spathidexia Townsend, 1912, the genotype of 

 which has been determined by Coquillett as Thelairodes cinereicol-
