 prolmhly ideiitiral with TrarhnJiihiH I't'tors, and lias;;iven prt'teivnco to 

 tilt' latter iiuiih', although it was jjiven in-arly twenty y«*ars at'terwards. 



Ill this paiMM' I have <'oiisi«l('r«'d Aninthiiihm as distinct from Tiarhy- 

 julut. My reasons for this may be t'onnd in the followint; chaiiuters 

 whi«*h I have culled from (Jeivais's descriptions iind tijfures of A. blain- 

 rilUi. 



Ocelli in nioic than one series; antenna* resemblinj; that of Camlmht; 

 first and last segments smooth; otiier sef^ments striate beneath and 

 armed above with eijfht rows of tubercles, eiy;ht on each seguient; also 

 a median dorsal series of indistinct tubenrles. 



SSides of first segment produced backwards (male?).

1884. — Chordeiimidw Latz«'l. Myr. OHt.-Uufjar. Monarch., ii, 171. 



Ac«'ording to the synonymy given above this family should be called 

 CraHindoHomidw an«I not Chordeumidw. 

 Gray's and not Koch's name should be employed.

I agree with Dr. Latzel in considering the Trichopetahim iuUoideH 

 Harger as belonging to the genus Chordeuma; although there is some 

 probability that it may be the young of some Campoden. LariuluH Ber- 

 lese, which was placed by him in the Lysiopetalida; is a member of the 

 Craspedosomidw, and is also identical with Chordeuma. 



17. Campodes.

nulatus VV^ood = C. JiaricorniH). 



Campodes Koch has always been overlooked by American authors, 

 as, in fact, have been nearly all the works of Koch. The result has been 

 the description of several genera that are identical with earlier names 

 of his. In the above synonomy I have included Pseudotremia Cope as 

 forming a part of Campodes, while Cryptotrichus Packard is also iden- 

 tical with the latter.
