 and from several taken at Westholme, V. I., May 15, 1917, 

 killed on same date. 



Adult. — The species was first described by Doane* in 1900, 

 who gave it the name of Cylindrotoma splendens. His spec- 

 imens, three males, were obtained from Unalaska. In 1901, 

 Coquilletf redescribed the species under the name of Cylin- 

 drotoma juncta from a male specimen collected at Virgin Bay, 

 Prince William Sound, Alaska. 



The following is Doane's description: 

 ^^Cylindrotoma splendens, sp. now. (PI. VIII, Fig. 21). 



Pale yellow and black ; head very pale yellow almost whitish; occi- 

 put, front, rostrum and palpi brown; first and second segments of anten- 

 nae whitish, first with a brown ring, other segments brown, cylindrical, 

 if bent back they would reach to about the middle of the first abdominal 

 segment ; thorax very pale yellow or whitish ; dorsum with three opaque 

 black stripes, the lateral ones merge anteriorly into broader brown 

 stripes which curve in and meet the median stripe; collar with a black 

 band; a large, black spot on the pleura between the base of the wing and 

 the anterior coxee, another over the anterior coxce, and another between 

 the first and second pair of coxas ; a smaller one just in front of the base 

 of the halteres, and a double on the posterior border of the metanotum; 

 scutellum with a median, brown stripe; halteres pale, slightly infuscated 

 above and at the tips ; legs brown, base of femora lighter ; tarsi and tips of 

 the tibia darker ; abdomen black ; male forceps large, brownish posteriorly ; 

 wings rather narrow, hyaHne; stigma pale, veins brown; auxiliary 

 vein ends abruirtly just before the stigma; the small, cross vein connect- 

 ing the first longitudinal vein with the costa is very faint and situated a 

 little beyond the middle of the stigma ; submarginal cell either longer or 

 shorter than the first posterior cell. (In two of my specimens it is longer 

 in one wing and shorter in the other.) Thus the praefurca may either 

 end in the submarginal cell or in the first posterior cell; five posterior 

 cells, the second sessile; discal cell elongated, somewhat pointed ante-
