202 THE MVIUAPODA OF NORTH AMERICA. 



Brown, sometimes with a bluish tinge ; antennae filiform, pilose, somewhat clavate; segments 51; scuta both 

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

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



I. canaliculars, Wood, Proc. A. N. S., 18G3, p. 1-2. 



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 cmarginate, and is furnished with two or three denticules, as 

 well as a double row of distant rigid hairs. The joints of the antennae 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 subscuta, 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. I have never seen a 

 male. Length, H inches.

I. brunneus, interdum cjeruleo tinctus; antennis filiform ibus, pilosis, nonnihil clavatis; segmentis 49; scutis 

 et supra et infra valde arcteque canaliculars ; muerone longo et recto; squama preanali triangula, vix acuminata. 



Brown, sometimes with a bluish tint; antenna; filiform, pilose, somewhat clavate; segments 49; scuta both 

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

 acuminate.

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

 light brown. The eyes an^ triangular, and are united by a dark band. The head has i t -. 

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

 rigid hairs. The antenna' 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 lew scattered hairs, but I 

 have never seen it pilose. Length. I of an inch.
