THE PSYCHODIDAE OF THE PACIFIC COAST. 



By Trevor Kincaid, TTnivereity of Washington. 

 Through the kindness of the Eev, A. E. Eaton, the British 

 authority on the Psychodidte, the writer has been made ac- 

 quainted with the classification of the family as accepted bj 

 European students. Tn Europe there are five genera, M'hich 

 are tabulated by Halliday in the following manner : 

 (a) With two simple nervures between the forked veins 



(b) rroboscis compressed, with maxillae nearly as long. 

 Wings pointed exactly at the end of the second simple 

 vein. Psychoda. 



(bb) Proboscis with broad, pointing liplets Maxillae ob- 

 solete. Labrura shorter than the labium. 

 Co) Wings broad, ovate, with an upward bellying sinus in 



the middle in the male. Ulomyia. 



(cc) Wipgs even in both sexes. Perfcoma. 



(aa) With one simple nsrvure between the forked veins. 



(b) Hindermost vein not much shorter than the rest. An- 

 tennae, with obconical joints, 14-jointed. 



Trichomyia. 

 (bb) Hindermost vein abbreviated. Antennae, with linear 

 joints, ISjointed. Sycorax. 



To these five genera, a sixth, Phlebotomus, has been added. 

 This genus seems to be more or less intermediate between 

 Halliday's primary divisions of the family, since Mr. Eaton 

 states that it has two simple veins between the forked ner- 

 vures, but is otherwise more closely related to Kycorax and 

 Trychomyia . 



Mr. Eaton records forty -one species of Psychodid.e for the 

 British Islands, distributed as follows : Vlomyia (1 sp.) ; Peri- 

 eoma (32 sp.) : Fsycfioda (6 »p.) ; Trichomyia {I sp.) ; Sycorau 

 (1 sp). 



All of the North American Psyciiodid.e so far described 

 have been placed under the genus Psychoda, but there is little 

 doubt that part of these will be referred to Pericoma. 



It is the purpose of the present paper to describe a number 

 of new species of Psychodid.e from various points on the Pa- 

 cific coast and to record certain notes in connection with spetdes 

 previously described , In the discrimination of the species in 

 the group very little use has apparently been made of the ven- 

 tral plate of the female. The writer believes that this struc- 

 ture is of great importance in this connection.
