154 THE CANADIAN ENTOMOLOGIST. 



Colour : vertex and face testaceous, usually a horseshoe-shaped light 

 mark on front, pronotum fuscous in front, forming a collar behind the 

 eyes, the posterior margin and broad lateral areas light, scutellum 

 testaceous, the carinae rather lighter. Elytra subhyaline, the nervures 

 brown or testaceous, sometime the apical ones clouded with fuscous. 



Described from eight females from Palmer Lake, Ridgeway and Fort 

 Collins, Colo. All taken in the mountains. 



Myndus S/ossoni, n. sp. 



Short and stout. Black, with the margins of elytra and a median 

 saddle light yellow. Length 4 mm., width 1.25 mm. 



Vertex very broad, but slightly carinate, scarcely angled with front; 

 front similar to impiger, eyes large, together with vertex nearly as broad 

 as the pronotum. Pronotum very short, angulate behind, scutellum as in 

 impunctatus, strongly tri carinate. Elytra shorter and broader than even 

 in impiinctatus. 



Colour : vertex, face, legs and pronotum leather-brown, lighter 

 below. Eyes, scutellum and elytra black, the costal margins of elytra 

 with narrow white stripes extending back beyond apex of clavus, a pale 

 yellow, illy-defined saddle occupying nearly all the claval areas back of 

 the apex of scutellum in the female and extending nearly to the costal 

 stripes in the male. 



Male pygofers with a semicircular excavation bearing a minute 

 knobbed median process. Styles long, touching in the middle, then 

 obliquely divergent. Anal tube with an acute median ventral process. 



Described from a single pair from Biscayne Bay, Fla. Collected by- 

 Mrs. Slosson and sent me by Mr. E. P. Van Duzee. The head is 

 proportionally larger (broader) in this form than in any other of our 

 species. 



CEclcus lineatus, n. sp. 



Resembling decetis, but smaller and lighter coloured. Vertex narrow, 

 right-angled. Length : $ 5.5 mm., o* 5 mm.; width 2.25 mm. 



Vertex reduced to a line, over five times longer than wide, slightly 

 wider in front than behind, projecting some distance in front of eye and 

 meeting front in a right angle, the lateral carinse elevated and nearly 

 meeting behind, forming a trough. Front concave, narrow, broadening 

 out below the middle, where it is over three times as wide as at the base,
