CHIBIQUIA.— OTUMBA. 7 



l. Chiriquia serrata, sp. n. 



Cola saxosa (Bol. ?, part.), Bruner, Bull. Lab. Nat. Hist. Univ. Iowa, iii. no. 3, p. 61 l . 



Body somewhat depressed. Face moderately retreating. Eyes large, globose, very prominent, elevated on the 



sides of the vertex. Antennae inserted below the level of the eyes, equidistant from the eyes and 



each other. Posterior ocelli barely below the level of the eyes. Vertex horizontal, elevated at the 



sides above the eyes to form transverse carinas running obliquely downward and inward to the 



mid-carina; the latter conspicuous from above, but hidden in side 



view by the prominent eyes, dividing opposite their lower part into 



high, rather widely divergent antrorse rami; from above, the vertex 



is nearly twice the width of one of the eyes, distinctly excavate, with a 



prominent median tooth (the mid-carina) reaching the level of the front 



margin of the eyes. Pace in profile strongly crenate, the middle arc 



formed by the prominent rami of the frontal costa, the upper arc by the 



eyes terminated by a minute portion of the transverse carinas of the 



vertex. Pronotum with truncate anterior margin and cuneate apex, of 



moderate width at the shoulders, granulate, rather flat above, with the 



exception of several prominent transverse rugae, which form on the 



mid-carina a series of low teeth between the shoulders and apex, and in 



front of the humeral angles a high cristiform eminence convexly arcuate 



in front, concave behind, its height from the shoulders equal to two-thirds 



the depth of the lateral lobes ; lateral lobes laminate, strongly produced, 



squarely truncate at the apex. Elytra minute, the exposed portion linear, five times as long as broad. 



Wings fully developed, reaching the apex of the pronotum, which passes the abdomen by about 1 millim. 



Anterior and middle femora very slender, the latter five times as long as broad, with irregularly sinuate 



margins ; (hind legs missing). 

 Total length, c? , 9*4 : pronotum 8 millim.

Two males. Prof. Burner's specimen is immature, and he referred it with some 

 doubt to another genus, as noted above ; but so similar is it to the adult male from 

 Chiriqui described that I have no doubt of their specific identity. 



. OTUMBA, gen. nov. 



Related to Metrodora. Pace strongly retreating. Eyes very large and prominent, elevated. Vertex truncate. 

 Pronotum somewhat depressed, flat above ; humero-apical carinae exceptionally developed and separated 

 from the lateral carinae by a deep groove ; scapular area very large ; external angles of lateral lobes 

 rectangular. Pemora elongate, slender. 



1. Otumba scapularis, sp. n. 



Amorphopus sp., Bruner, Bull. Lab. Nat. Hist. Univ. Iowa, iii. no. 3, p. 61, t. 3. fig. 2 l . 



Antenna long, reaching the humeral angles, filiform, very slender, joints 9-12 the longest. Pace very 

 retreating, convex opposite the insertion of the antennas, which are placed a little below the level of 

 the eyes. Eyes very large, globose, and prominent. Posterior ocelli exceptionally large, situated 

 between the lower part of the eyes. Vertex truncate, scarcely as wide as one of the eyes, horizontal, 

 terminating anteriorly in oblique transverse carinae ; the mid-carina distinct but very small ; facial 

 costa forking at the middle of the eyes (behind the ocelli) into very narrowly divergent, nearly
