This species is closely allied to the next, but differs very much in 

 color and in the characters of the anterior segments, and male genitalia. 

 I have seen a male and a female which were collected by Mr. Charles 

 B. Brainier. The female has a browner pattern of coloration and the 

 red is not so vivid as in the male.

8. Fontaria rubromarginata, sp. nov. 



Diagnosis. — Very similar to Fontaria evides, but the first three seg- 

 ments of male attenuated; vertex, sulcus deeper; femur more swollen; 

 anterior border of first and posterior of other segments red. 



Type.—U. S. Nat, Museum. 



Habitat. — Balsam, Jackson County, N. C. 



This species is closely related to the preceding. It differs, however, 

 much in color and in the character of male genitalia. As compared 

 with the male of F. evides, the following points may be worthy of note: 



Browner, legs yellow; lateral plates not so sharp; legs of male more 

 crassate; distal fourth of genitalia very much expanded near the end; 

 basal spine stout, bifid; two lateral lobes, the first trifid, the other 

 bifid; length of body, 38"""; height, 5 mm ; width of segment, 6.3 m,u ; 

 width of tenth, 10 ,nm ; antennae, 8.3"" 11 . 



The characters of ventral plates and cox* are the same as in F. evides. 



These notes are based upon a male collected by Prof. George T. At- 

 kinson, which only has the right leg changed into a copulatory organ. 



9. Pontaria montana, sp. nov. 



Diagnosis. — Similar to Fontaria trimaeulata (Wood) but larger, espe- 

 cially the breadth; dorsal plates less convex, lateral carinas larger and 

 more produced; legs of male less crassate, shining black, yellow spots 

 very distinct, legs light brown. 



Type. — U. S. Nat. Museum. 



Habitat. — Wolf Creek, Cooke County, Tenn. 



This species is very closely related to F. trimaeulata, as is shown by 

 the coloration and genitalia, but the latter are more strongly coiled and 

 with the basal spine larger. Comparing the males of the two species, 

 it may be said that in F. montana the different parts are larger, but 

 more slender. 



I have examined a male collected by Mr. Charles B. Branner. This 

 species is the southern representative of F. trimaeulata, but it is not 

 probable that they will merge into one as the characters of the male 

 genitalia are too much unlike.
