40. BASSUS CINCTUS (Cresson) 



Microdus ductus Cresson Canad. Entom., vol. 5, 1873, p. 53. 

 Microdus pimploides Viereck, Trans. Kan.s. Acad. Sci., vol. 19, 1905, p. 27G. 

 Bass^is winkleyi Viereck, Bull. 22, Conn. Geol. and Nat. Hist. Survey, 1917 

 (1916), pp. 227 and 229. 



Type. — The type of cinctus is in the Philadelphia Academy of 

 Sciences; that of pimploidet^ is at the University of Kansas; and 

 that of winkleyi is in the collection of the agi'iculture experiment 

 station at New Haven, Connecticut. 



After studying these three types I am of the opinion that they 

 belong to the same species; pimploides and winMeyi therefore are 

 suppressed as synonyms of cinctus, which has priority. A small 

 rather slender species, varying in length from 3 to 4.5 mm.; face 

 distinctly broader than long, polished, malar space less, usually much 

 less, than half the length of the eyes; third segment of labial palpi 

 very small, sometimes indistinct; temples sloping gradually from 

 the eyes, but not especially narrow; antennae slender, 30 to 37 seg- 

 mented in the material examined; ocell-ocular hne not distinctly 

 quite twice the greatest diameter of an ocellus; parapsidal furrows 

 sharply impressed, usually minutely foveolate; furrow in front of 

 3015—27 5
