THE MYKIAI'ODA OF NORTH AMERICA. 



Brown, sometimes with a bluish tinge ; antenna; filiform, pilose, somewhat elavate; segments 51; scuta both 

 above and below closely canaliculate, each furnished with a single series of long distant hairs; niucro long, 

 straight; anal scales with long hairs; preanal scale triangular, acuminate. 



I, canalictjlatus, Wood, Proo. A. N. S., 1863, p. 12. 



The color of this species is a dark brown, with sometimes a bluish tint, and very generally- 

 mottled with light brown. The triangular eyes are connected by an obscure black band. 

 The labial margin is broadly emarginate, and is furnished with two or three denticules, as 

 well as a double row of distant rigid hairs. The joints of the antenna: are tipped with 

 white. The first scutum is, in the female, slightly prolonged laterally, where it is 

 rounded off; on its anterior surface there is a dark, somewhat crescentic, blotch. The 

 anterior of the two subacute, forming each scutum, is closely and deeply canaliculate 

 through its whole circumference ; it is broader than the posterior, and very slightly eleva- 

 ted, so as to give the body somewhat of a moniliform appearance. The ring of hairs 

 surrounding each scutum is frequently imperfect ; it may be from the handling of the 

 specimen. The posterior subscutum is smooth above, and distantly and shallowly canali- 

 culate below. The posterior portion of the body is very pilose. T have never seen a 

 male. Length, 14 inches.

Brown, sometimes with a bluish tint; antennae filiform, pilose, somewhat elavate; segments 4!); scuta both 

 above and below deeply and closely canaliculate; niucro long and straight; preanal scale triangular, scarcely 

 acuminate. 



I, laqueattjs, Wood, Proc. Acad. Nat. Sot., 1864, p. 18. 



The color of this species is brown, sometimes bluish, mottled, almost areolated, with 

 light brown. The eyes are triangular, and are united by a dark band. The head has its 

 anterior margin broadly emarginate, denticulate, and furnished with two rows of distant 

 rigid hairs. ' The antennae have their proximal joints nearly cylindrical, and are light 

 colored, with their articles indistinctly tipped with white. The first scutum has rather 

 small lateral processes, and is ornamented on its anterior border with a dark band. The 

 anterior subscuta are deeply and closely canaliculate over the whole of their surface. The 

 anal scales are furnished with a series of long hairs along their valvular margin. The 

 posterior portion of the body is generally adorned with a very few scattered hairs, but I 

 have never seen it pilose. Length, ;i of an inch.
