GENUS SABETHES ROBINEAU-DESVOIDY. 

 Sabethes cyaneus Fabricius. 



Cnlex cyaneus Fabricius, Syst. Antl., 35, No. 9, 1805. 



Sabethes nilidus Theobald, $ , Mon. Culic., ii, 347, 1901. 



Sabethoides confusus Theobald, Mon. Culic., iii, 328, 1903. 



An examination of the descriptions of Fabricius and Wiedemann seems 

 to us to clearly indicate that Fabricius had before him this Sabethid, 

 rather than the species Haemagogus splendens Williston which Mr. Theo 

 bald has made a synonym of Fabricius' old species. The abdominal mark 

 ings form a lateral line as described, which is not the case in splendens, 

 and the color of the thorax also agrees. 



GENUS WYEOMYIA THEOBALD. 

 Wyeomyia pertinans Williston. 



Aedes pertinans Williston, Trans. Ent. Soc., Lond., 271, 1896. 



Aedes pertinans Giles, Gnats or Mosq., 352, 1900. 



Wyeomyia pertinuns Theobald, Mon. Culic., ii, 272, 1901. 



Wyeomyia pertinans Giles, Gnats or Mosq., 2 ed., 498, 1902. 



Aedes pertinans Giles, Gnats or Mosq., 2 ed., 483, 1902. 



Wyeomyia pertinans Blanchard, Les Moust., 424, 1905. 



Wyeomyia ochrura Dyar & Knab, Journ. N. Y. Ent. Soc., xiv, 229, 1906. 



Wyeomyia ochrura Dyar & Knab, Proc. Biol. Soc., Wash., xix, 141, 1906. 



We quote the above synonymy for this widely distributed species, hav 

 ing now before us cotypes of pertinans, which Dr. Williston has very kindly 

 sent us for examination. It is a true Sabethid, not a Culex (see remarks 

 under Culex divisor Dyar & Knab, Journ. N. Y. Ent. Soc., xiv, 222, 1906). 



GENUS CULEX LINNAEUS. 

 Culex ocellatus Theobald. 



Culex ocellatus Theobald, Mon. Culic., iii, 222, 1903. 



Mr. Urich has discovered the larva of this pretty species, which he had 

 formerly bred from a pupa in Bromelia water. It falls in our table (Journ. 

 N. Y. Ent. Soc., xiv, 207, 1906) with imitator, consoJator and inimitabilis,be- 

 ing a close ally of these species, with its extremely long air tube and gen 

 eral slender, colorless appearance. It differs from rejector in the smaller 

 pecten with two detached teeth, which are as in consolator ; it differs from 

 inimilabilis in having more teeth in the pecten (it has seven while inimita- 

 bilis has five) and in having a median hair tuft on the tube instead of a 

 single hair ; it differs from consolator in having a small multiple tuft on the 

 tube beyond the middle and a subapical single hair instead of four rather 

 long 2-haired tufts. It is nearest to imitator Theobald, so much so that we 

 can not demonstrate any differences in the limited and somewhat defective 

 material before us (the head hairs of imitator have not been studied). The 

 antennae of ocellatus are slender, pale, the tuft from a small notch well be 

 yond the middle ; upper head tuft in fours, lower a single thick spinulated 

 hair. 



Bred by Mr. Urich from Bromelia water, Sangre Grande, Trinidad.
