ing distad to their acute apices and less than twice as long as broad, 

 between the bases of which the subgenital plate is triangularly 

 produced and unarmed. 



To the known Panamanian species it will be seen that nearest 

 affinity is with C. cabimae Hebard, that species differing in the mark- 

 ing of the head, wider interocular space, very much more elongate 

 fourth joint of maxillary palpi and differently shaped male styles. 



Type: cT; Bartica, British Guiana, January 10, 1913. [H. S. 

 Parish.] [Acad. Nat. Sci. Phila. Type no. 5370.] 



Size medium for the small species of the genus; form depressed, 

 surface glabrous. Head with occiput largely exposed. Interocular 

 space (.45 mm., in cabimae .55 mm.) two-thirds the width be- 

 tween the antennal sockets. Maxillary palpi with fifth joint 

 slightly shorter than fourth, fourth joint approximately four-fifths 

 as long as third. Pronotum transverse, subelhptical; greatest 

 width meso-caudad; cephalic and caudal margins transverse, 

 feebly convex; latero-cephalic angles distinctly more broadly 

 rounded than latero-caudal angles. Tegmina surpassing apex of 

 abdomen by about the pronotal length, strongly elongate lanceo- 

 late, with apex sharply rounded, distinctly more acute than in 

 cabimae; discoidal vein with numerous branches, the more distal 

 of which are subobsolete; discoidal sectors (9) oblique. Wings and 

 venation very delicate; appendicular field nearly as long as broad, 

 basal outline forming very sHghtly more than a right angle ; costal 

 veins moderately heavily clubbed distad. Dorsal surface of abdo- 

 men with sixth segment weakly specialized mesad, as characteristic 

 of the genus. Supra-anal plate strongly transverse, very weakly 

 triangularly produced. Subgenital plate with lateral portion of 

 free margin weakly oblique, nearly transverse, straight to the two 

 short styles, which are deeply inset, between these the subgenital 

 plate is minutely triangularly produced and unarmed. Styles 

 heavy, nearly twice as long as greatest width near base,^i the lat- 

 eral margins from that point to the small apical portion, which is 

 formed by a folding over of the style, forming a small triangular 

 apex, directed dorso-laterad. Limbs and their armament, pulvilli. 

 tarsal claws and arolia as characteristic of genus. ^^ 



Allotype: 9 ; same dataastype, except taken on January 30, 1913.

Agrees closely with male, differing in the following features. 

 Interocular space broader (.65 mm.). Tegmina shghtly less elon- 

 gate. Dorsal surface of abdomen not specialized. Supra-anal 

 plate triangular and rather strongly produced, with lateral margins 



^' In the male paratype these styles are distinctly shorter than in the type, with 

 contour, however, similar.
