136 THE BLATTIDAE OF PANAMA 



The general coloration is richer and the male genitalia are distinc- 

 tive, particularly in the type of specialization of the median portion 

 of the subgenital plate. 



In tegminal form and type of coloration closer similarity is 

 shown to C. gemmicula, here described, under which species compari- 

 son is made, and to C. albonervosa Rehn. the much richer and more 

 striking coloration, much fewer tegminal veins and differently 

 specialized male subgenital plate readilydistinguishing that species. 



Type. — & ; Gatun, Canal Zone, Panama. July 28 to August 5, 

 1916. (D. E. Harrower.) [Hebard Collection, Type no, 497.] 



In the features not mentioned here the present species agrees fully with C. cahimae, 

 described on page 134. Size medium for the small species of the genus. Interocular 

 space about one and one-third times the occipital ocular depth, two-thirds the 

 width between the antennal sockets. Maxillary palpi with third joint slightly longer 

 than fifth, the latter decidedly enlarged, fourth joint slightly shorter than fifth. 



Pronotum transverse, nearly elliptical, greatest width almost mesad ;'''*' cephalic 

 and caudal margins transverse, very feebly convex, cephalic angles more broadly 

 rounded than caudal angles. 



Tegmina surpassing abdomen by more than pronotal length, decidedly elongate 

 lanceolate, costal and sutural margins evenly and feebly convergent, straight from 

 proximal third to distal portion of tegmen, where they are convex convergent, the 

 sutural margin over a greater distance, to the decidedly acute-angulate, very sharply 

 rounded apex; scapular field broad, much broader than in transliicida; discoidal vein 

 longitudinal, with (thirteen to seventeen in series) costal branches, the more proxi- 

 mal of which (about seven) are distinctly arcuate, with or without a branch at 

 apex toward sutural margin, discoidal and median veins much closer together 

 than in translucida; discoidal sectors (eight to ten in series) oblique. 



Wings of the general type found in the Pellucida Group, not as in the Translucida 

 Group; with intercalated triangle rather than appendicular field relatively moderately 

 well developed, its length approximately equal to its width, basal outline forming an 

 angle distinctly less than a right-angle; (nine to twelve in series) costal veins briefly 

 and heavily clubbed distad, discoidal and median veins connected by (seven) 

 inconspicious transverse veinlets, other distal transverse veinlets between median, 

 ulnar and anal veins extremely weak. Median depression of sixth dorsal abdominal 

 segment shallow. 



Supra-anal plate strongly transverse, length slightly over one-fifth proximal width, 

 caudal margin broadly convex, showing weak indication of bilobation. Subgenital 

 plate very small, brief lateral margins concave to the large styles which are deeply in- 

 set in sockets, the dextral the more so; styles elongate, length about three times basal 

 width, trilamellate, tapering from large and briefly swollen base (this the more ample 

 for the dextral style) to acute apex, which extends beyond the distal margin of the 



"""' In translucida and C. panamae here descrilxHl, with greatest width mcso-caudad 

 and latero-cephalic anj^lcs much more broadly rounded tlian latero-iaudal angles.
