136 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



character alone given to separate the unique specimen described 

 as fallax from granadensis, taken at the same locahty, indicates 

 that the vahdity oi fallax is highly doubtful. 



The measurements of the specimen here recorded are as follows : 

 Length of body, 16.8; pronotum, 5.5; cephalic coxa, 4.8; cephalic 

 femur, 5 mm. Width of head, 3.7; of pronotum at widest point, 

 2.3 mm. 



Pogonogaster latens new species (Plate XVIII, figs. 6 and 7.) 



This remarkable mantid is not widely separated from the 

 genotype, P. tristani Rehn.^^ It differs in having the pronotal 

 collar proportionately slightly shorter, with the two median ele- 

 vations represented by slightly raised swellings rather than blunt 

 conical projections; the supra-coxal expansion not as decidedly 

 produced on each side, these portions less delicate with margins 

 not as strongly irregularly serrate; shaft with median carina dis- 

 tinct but lacking nodes, the flexure dorsad of the caudal portion 

 not as sharp, the pair of nodes there found heavier and lower, as 

 are the nodiform projections mesad on the caudal margin of the 

 mesonotum, metanotum and median segment; abdomen with 

 large and striking foliaceous plates only mesad on first, second 

 and third dorsal segments, these irregular in outline but lacking 

 spiniform marginal projections; succeeding abdominal segments 

 only moderately cristate mesad, this strongest on fourth segment; 

 supra-anal plate more bluntly rounded distad, and limb arma- 

 ment similar except that the minute microscopic denticulations 

 of the margins of the cephalic coxae and proximal portions of the 

 ventral margins of the cephalic tibiae are more numerous and 

 even smaller, while the cephalic tibiae are supplied ventro-ex- 

 ternally each with two minute spines curved distad. 



Type. — 9 ; Rio Aguatal, Cauca, Colombia. Elevation, 5900 

 feet. November, 1908. [United States National Museum.] 



Size medium; form very slender, except the abdomen which is moderately 

 stout. Head crushed; oceHi obsolete. Pronotum elongate, collar nearly half 

 as long as shaft, showing a large, moderately raised swelling meso-caudad and 

 a lesser swelling mcso-cephalad; pronotal margins microscopically denticulate; 

 supra-coxal expansion with lateral portions triangularly i)roduccd, directed 

 slightly ccphalad, with apex bluntly rounded, the angle there fornicHl slightly 

 less than a rectangle; shaft ^with a distinct medio-longitudinal carina, shaft 

 moderately bent dorsad near the caudal extremity and there supplied with a

 nearly adult, from La Palma, Costa Rica, is in the Academy collection.
