236 ORTHOPTERA. 



is largely brown or dull black, the lighter portions being confined to a few scattered blotches of testaceous 

 towards the base and some of the veinlets along the dorsal and discal areas. The wings are deep carmine 

 on the disk back of the dilated area, beyond and apically on the costal field this colour is varied with 

 black, the entire margin from the apex to the anal angle being black-bordered. Antennae flavous, save 

 the extreme apex, which is infuscated. 

 Length of body, tf 45-50, $ 60; of pronotum, tf 16-17, ? 22 ; of tegmina, tf 38-40, $ 40 ; of hind 

 femora, <3 23, £ 26 millim. 



Hab. Mexico, Medellin in Vera Cruz (Heyde, in coll. L. Bruner), Temax in 

 N. Yucatan (Gaumer). 



This species has the appearance of living among fallen leaves in the shadows of 

 tropical forests, where its sombre colours would be an excellent protection for it 

 against some of the larger insectivorous birds and various reptiles that are at home in 

 such localities. 



10. Taeniopoda bicristata, sp. n. 



Similar in general appearance to the preceding species, but differing from it in the somewhat smaller size and 

 the slightly narrower pronotum, with a much higher and longer crest, the posterior section of which is 

 higher and longer than the anterior one. The disk is much less flattened and has the hind margin 

 decidedly acute-angled ; and, as compared with T. obscura, the tegmina and wings are somewhat 

 abbreviated, while the pronotal carinas are black throughout in T. bicristata, as compared with the other 

 species, where they are streaked with flavous or ferruginous. 



Length of body, $ , 54 ; of pronotum 24, of tegmina 32 millim. 



Hab. Mexico (coll. L. Bruner). 



The type, a $ , is marked simply " Mat.," which possibly means Matamoros, Puebla. 

 It was given to the writer some years ago while he was visiting the Mexican National 

 Collections kept at Tacubaya. The insect approaches what I take to be Drury's 

 T. centurio in its general structure much more closely than it does T. obscura, with 

 which it has been compared, but imitates the latter in colour.

The Mexican and Nicaraguan specimens referred to T. centurio seem distinct from 

 all the other species recorded in the present work. Whether or not it is the insect 

 figured by Drury is difficult to state without examining examples from the original 

 locality, Honduras. The Nicaraguan material is more likely to belong to it than that 

 recorded from Mexico, and especially is this likely to be true of such specimens as
