MORGAN HEBARD 133 



The ootheca is carried with suture dorsad, this suture with 

 minute double-knobbed projections separated by about twice 

 their own diameter. Surface of ootheca strongly convex, weakly 

 roughened and covered with a scattering of minute hairs. The 

 extruded distal surface is curved evenly upward to base of suture 

 without a keel.

Ceratinoptera tropaia '' new species (Fig. 4.) 



This species is related to C. nahua, the greatest differences 

 in males being.found in the smaller size, decidedly less transverse 

 pronotum, truncate tegmina, vestigial wings, less decidedly 

 specialized mesal portion of seventh dorsal abdominal segment 

 and solid and darker general coloration. 



Type: cf ; Motzorongo, Vera Cruz, Mexico. February 1892. 

 [Hebard Collection, Type No. 417.] 



Description o/ Type.- — Size very small, form moderately stout. Eyes very 

 widely separated, not quite reaching as far as mesal portion of dorsal margin 

 of antennal sockets, ocellar spots absent (see footnote 9). Head and maxillary 

 palpi as given in generic description. Pronotum proportionately deeper than 

 in nahua, margin evenly rounding to latero-caudal angles which are rather 

 broadly rounded, rectangulate; caudal margin truncate, transverse. Teg- 

 mina corneous, very slightly longer than wide, sutural margins attingent 

 distad, caudal margins truncate and moderately oblique toward the sutural 

 margins, this truncation causing a decided inward bending of the anal 

 vein, brief proximal portions of other veins almost indistinguishable. Scv- 



^^In addition we have before us an immature example of the genus from 

 Cauca, Colombia. This specimen is dark shining blackish brown in general 

 coloration with pronotum immaculate, but in other features of paler color- 

 ation agrees exactly with the immature examples here recorded. 



^^ From Tpo7rata = a change from. In allusion to the differences from the 

 genotype in the organs of flight.
