The "confusion worse confounded" in which the mosquitoes of 

 America are at present enveloped may be illustrated by the two following 

 instances : 



In the August number, Canadian Entomologist (1904) I described 

 a mosquito from Benecia, Cal , as Grabhamia de Neid7nanfiii^ and, some 

 time afterward, received a note from Mr. Coquillett, stating he believed it 

 to be his Culex sqiia^niger (originally published as TcBniorhytichus). As 

 the insect did not belong to Culex, as restricted by Theobald, and I had 

 hot seen Mr. Coquillett's description, I let the matter rest till I should 

 have further information. Now, for some time, I have been practically 

 convinced -that Mr. Coquillett was correct, and that Grabhamia de 

 Neidmajinii must sink as a synonym of his sqiiauiiger, the genus of which 

 seems, however, to be still undetermined, Mr. Coquillett now referring it 

 to Culex, Dr. Dyar to Grabhamia, and Dr. Felt to Ctdicida. 



In June, 1905, in this magazine I described another mosquito (from 

 the Sierra Nevada Mts.) as Tceniorhyndius Sierrensis, the description 

 benig made from several very imperfect specimens. During the fall of 

 1905 some specimens in good condition were received, and to my as- 

 tonishment I found that, partly from an error in transcribing my original 

 .ijptes, partly from the poor condition of the specimens, not only had a 

 gross error in the description of the tarsi arisen, but that the scales of the 

 ;Scutellum, which are long, very broadly spatulate, and only slightly curved, 

 fwitha few slender curved scales, apparently mostly at the base of the 

 ■S'cutellum, carried it out of Tceniorhyiichus. The description aS to colours, 

 etc , as now corrected, makes it more than probable that it is Coquillett's 

 varipalpiis, but if this be so, it is in any case not a Culex, nor a 

 Tcetiiorhyjichus, but probably lies near Finiaya. 



The following is apparently a new mosquito, being one of the very 

 few in the U. S. having light apical abdominal markings : 

 ^ Culex Frickii, n. sp. — Female : Hea(i covered with pale ochraceous, 

 almost white scales, long curved ones, heavily intermingled with dark 

 brown forked scales on the occiput and vertex, flat lateral scales, light 

 around the eyes, with a {^.\y dark bristles projecting forward ; antennae 

 brown, verticels and pubescence brown, first joint with a few light scales, 

 basal joint covered witii "frost" and a few white scales ; palpi dark brown, 



y\pril, K/"^'.
