THE PSYCHODIDAE OF THE PACIFIC COAST. 



BY THHVOK KIXCAID, I'niversity of Washington. 

 Through the kindness of the KY\ . A. E. Eaton, the British 

 authority on the Psychodidas tlie writer has been made ac- 

 quainted with the classification of the family as accepted by 

 European students. In Europe there are live genera, which 

 are tabulated by Halliday in the following inaniier: 

 (a) "With two simple uervures between the forked vcin.- 



(b) Proboscis compressed, with maxilla 3 ni-arly as lony . 

 Wings pointed exactly at the end of the second simple 

 vein. I'sticlnxlii. 



( bb) Proboscis with broaO., pointing liplels Maxilla 3 ob- 



solete. Labrum shorter than the labium. 

 c Wings broad, ovate, with an upward bellying siuu> in 



the middle in the male. I'lunnikt. 



'\cc) A\'i'g-s even in both sexes. l'< 'i-ii-onm . 



'.an With one simple uarmre b3twec:i (lit- forked vein> 



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

 tenna 1 , with obcooical joint?, 14-jointed. 



Trichomym. 

 > bh) Hiuderiiid-t vein al)breviaicd. Antenna 1 , with linear 



joints, 15-joiuted. b'ycoi-f>.>-. 



To these five genera, a sixth. /V/V^o/i*;////*. has l)een 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 uer- 

 vures, but is otherwise more closely related to Si/cf>r<i.> -and 

 Trychomyia. 



Mr. Eaton records forty-one species of PsyrimniP.K tor the 

 British Islands, distributed as follows : ('!<ni/i<i i 1 sp. ) ; I^ri 

 count ('.\'l sp. i : I'.si/rlHHlit ( (> x|. , : 'l'ric/i<>iin/i \ -p. i ; Si/cdiii.i 

 (1 Sp.. 



All of the North American I'svciK l)t i>-i: so far described 

 ha\c been placed under the genus I'si/i-hoila. but there is little 

 doubt that part of these will be referred to /Vr/Vo//m. 



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

 of new species of PsvciidDiD.i: from various points . .11 the Pa 

 cilic coast and to record certain notes in connection with species 

 previously described. In the discrimination of I lie species in 

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

 tral plate of the female. The writer belie\ es thai this struc- 

 ture is of great importance in this connection.
