costa, ochre yellow in the male, distinct postocular bar shining seal 

 brown; head of the female from the dorsal margin of the postocular 

 bar and the margin of the fastigium ventrad seal brown, more or less 

 shining ; eyes in the male mars brown, in the female burnt lunber ; an- 

 tennae wath about the proximal third of the pale general color, the distal 

 two-thirds of the darker shade. Pronotum with the lateral angles ochre 

 yellow, the protuberance of the median carina blackish; lateral lobes 

 shining seal brown except for an oblique bar of dull ochre yellow which 

 crosses the ventro-caudal lobe and is continued more or less distinctly 

 across the seal brown pleura. Tegmina bicolor, dorsad buff yellow, 

 ventrad seal brown. Abdomen with the seal brown lateral portions 

 distinctly separated from the dorsum, on the third and fourth segments 

 the lighter dorsal shade is continued ventrad and obliquely cephalad a 

 short distance in a subelliptical patch, the median carina of the pro-

Measurements. 



Length of body, 14.2 mm. 24 mm. 



Ijength of pronotum, 4 " 5.2 



Greatest dorsal width of the pronotum, ... 3 " 4.3 " 



Length of tegmen, 2.5 '' 3 5 



Length of caudal femur, 12.5 " 15.5 " 



A series of five paratypic specimens, three males and two females, 

 have been examined in addition to the types. Little variation is 

 noticed, except that two of the males have the lighter shades more 

 greenish-yellow than the others. 



The peculiar and striking appearance of this species should serve to 

 readily distinguish it, the large head of the female and the lacquer-like 

 character of the seal brown color being very striking. 



I take pleasure in dedicating this species to Mr. Hebard, as a slight 

 token of appreciation of much kindly interest and assistance. 

 Microtylopteryx fusiformis n. sp. 



Type : & and 9 ; Carrillo, Costa Rica. [Hebard collection.] 



Allied to M. hebardi, but differing in the shorter limbs, the more 

 robust body, the broader tegmina, rather different color pattern and a 

 number of minor characters. 



Size medium (female) to small (male) ; form fusiform, very slightly 

 compressed ; surface strongly punctate dorsad. Head with the occiput
