APPENDIX. 



SOME NEW SPECIES OF KANSAS CHIRONOMID^. 



By O. a. Johannsen. 



Among a lot of Chironomid9e submitted to me for identifi- 

 cation by Mr. E. S. Tucker, of the museum of the University 

 of Kansas, were several specimens which could not be classi- 

 fied with any previously described species, and are therefore 

 presented here as new. 



Bezzia elegantula, n. sp. 



Female. — Head and proboscis yellowish, the tip of the 

 latter and the palpi fuscous. Eyes nearly contiguous over 

 the base of the antennae. Antennae, including the large basal 

 joint, yellow. Thorax deep yellow, subshining, humeri and 

 pleura with a grayish bloom ; dorsum with four rows of fine 

 setae, also a marginal row near the base of the wing. Ab- 

 domen yellowish brown, posterior segments a little darker, 

 posterior margins of all the segments pale yellow ; venter 

 yellow, posterior margins of the segments on the sides black. 

 Legs, including coxae, yellow; tips of hind femora, bases of 

 hind tibiae and tips of all tibiie brown ; tips of all tarsal 

 joints also narrowly brown. Claws very unequal, under side 

 of fifth tarsal joint of all the feet with one or two pairs of 

 stout, blunt, black spines ; hairs of all tibiae and tarsi black. 

 Wings bare, pale, veins yellow; the tip of the radius ends 

 about one-fourth of the wing length from apex ; the media 

 petiolate, the stem but little shorter than the cross-vein. 

 Halteres yellow, with pale green knob. Length, 2 mm. Col- 

 lected in July at electric light on bridge across Kansas river 

 at Lawrence, Douglas county, Kansas, by E. S. Tucker. 



The homology of the Ceratopogon wing venation given on 

 plate 17, figures 13 to 16 (Bulletin 86, New York State Mu- 

 seum), I now believe to be incorrect. What is marked R2+3 

 should be R4+5, while those marked R4+5 and M constitute the 

 anterior and posterior branches of the media.
