MORGAX HEBARD 105 



around the cephalic margin, there being still narrower and somewhat suffused. 

 Tegmina shining deep chestnut brown, translucent when spread, with marginal 

 field narrowly bordered with translucent warm buff; portion of dextral tegmen 

 concealed when at rest hyaline but embrowned, ^^'ings hyaline faintly em- 

 browned except in intercalated triangle, with a very faint iridescent luster, 

 veins and entire area of costal veins chestnut brown. Body, abdomen, except 

 dorso-proximad where the abdomen is paler, and cerci chestnut brown. Limbs 

 light buff, proximal portion of coxae chestnut brown, tibiae and tarsi tinged 

 with brown. 



Ill addition to the tj^pe and allotype, a single paratypic male 

 from the same locality is at hand. 



Ischnoptera colombiae new species (Plate XVI, figs. 8, 9 and 10.) 



This insect is so similar to /. apolinari that careful comparison 



shows the majority of features exactly as given for that species. 



We therefore describe below only the characters separating these 



species. 



Type. — cf ; Valle de Las Pappas to San Augustin, Tolima, 



Colombia. April 6, 1912. [Hebard Collection, Type No. 214.] 



Interocular space moderately wide, three-fifths the ocular depth, four-fifths 

 the interocellar width. Internal margins of ocelli forming a sharply rounded 

 angle with interocellar area, not raised. MaxiUary palpi shorter than in apoli- 

 nari, with fifth (distal) joint slightly longer than third. Supra-anal plate with 

 production of similar %y\>e but uniformly less heavily chitinous, this portion 

 slightly longer than its pro.ximal breadth; ventral surface lacking a projection. 

 Concealed genitalia : an elongate, heavy, moderately chitinous plate is situated 

 dextrad and directed caudad, adjacent to which mesad are two verj' elongate 

 and slender chitinous projections, the longest of which terminates in several 

 long contiguous spines. Subgenital plate very short, scoop-shaped, surface 

 entirely convex; free margin convex except meso-sinistrad where a moderate 

 obtuse-angulate emargination occurs, the convexitj' strongest meso-dextrad 

 where the production is greatest. Sinistral style situated in sinistral angulate- 

 emargination, elongate, decidedly stouter than this style in apolinari, flattened 

 cylindrical, feebly sinuous, tapering slightly to the rounded apex, unarmed. 

 Dextral style situated on dorsal surface of distal margin sinistrad on dextral 

 production, verj^ small, slender, cylindrical, unarmed, hardly tapering to the 

 apex, which is directed sinistrad. Limbs short, strikingly shorter than in 

 apolinari. 



Length of body, 12.6-^; pronotuin, 3.1; tegmen, 17; caudal femur, 3.7 mm. 

 Width of pronotum, 4.1; tegmen, 4.4 mm. 



Coloration throughout as in apolinari except that the pronotum is slightl}' 

 less (lark, shining dark chestnut ])rown, with narrow warm buff marginal 

 marking more sharjjly defined cephalad, but very narrowly interrupted meso- 

 cephalad. Limbs slightly darker than in apolinari, general coloration ochra- 

 ccous-buff, but similarly marked. 



The type is unique. 



^' The abdomen in this specimen is decidedl}- drawn in.
