Tliis species is closely allied to the next, lint ditleis very mnch in 

 i-oloiand in tliecliaraet«Ms of the anterior sej^iiients, and male <;('nitalia. 

 I have seen a male and a female which were collej'ted by Mr. Cliarles 

 B. I>ianiier. The female has a browner patt«Mii of coloration and the 

 red is not so vivid as in the male. 



8. Fontaria nibromaigiuata. sp. nov. 



hiagnoxis. — ^'ery similar to Fouinrin t rides, bnt the first three seg- 

 ments of male attennated; vertex, salens deeper; fennir more swollen; 

 anterior border of first and ])osteri(n- of other segments red.

This speties is closely related to the jireceding. It differs, however, 

 mnch in color and in the character of male genitalia. As <'ompared 

 with the male of F. < riths. the following points may be w<irthy of note: 



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

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

 basal sjMne stout, bifid; two lateral lobes, the first tritid, the other 

 bifid; length of body, 38"""; height, 5"""; width of segment, (5.3"""; 

 width of tenth, 10"""; antenna-, 8.3""". 



The characters of ventral jilates and coxa* are the same as in F.eridcs. 



These notes are based upon a male collected by Prof, (Jeorge T. At- 

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



9. Fontaria montaua. sp. nov. 



Didf/iiosis. — Similar to Foniaria frimnculata (Wood) but larger, espe- 

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

 more proihued; legs of male less crassate, shining black, yellow spot^ 

 veiy distinct, legs light brown. 



Type. — V. S. Nat. Museum. 



Habitat.— WoW Cvet^k, Cooke County, Teun. 



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

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

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

 it may be said that in 1\ montaua the different parts are larger, but 

 more slender. 



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

 species is the southern representative of I\ frimacidata, but it is not 

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

 genitalia are too nnich unlike.
