scattered, similar nodules. The limits arc unspeciali ed, the caudal 

 metatarsi simple, equalling the combined length of the succeed- 

 ing joints. The ninth (distal) dorsal abdominal segment is slightly 

 longer than broad, truncate at apex. The sixth ventral abdom- 

 inal segment is produced in a small rounded mesal projection at 

 the base of the operculum. The operculum is broken.

The species appears to be nearest B. horni Redtenbacher. It 

 agrees in being apterous, with vertex smooth, eighth dorsal ab- 

 dominal segment with lateral margins straight and horizontal, 

 median segment not more than half again as long as the meta- 

 notum, femora not bearing lobes and ninth (distal) abdominal 

 segment with apex rounded, not bilobate. In addition to having 

 longer limbs and mesonotum, but metanotum and median seg- 

 ment of approximately the same length, the genitalia show the 

 present insect to be distinct. Were the description of horni ade- 

 quate, other differential characters could doubtless be given. 



Type. — cf ; Susumuco, Cundinamarca, Colombia. Elevation, 

 2600 feet. August, 1913. (From A. :SIaria.) [Hebard Collec- 

 tion, Type No. 456.] 



Size medium for the genus, form slender. Head ovate, weakly narrowed 

 caudad, cheeks about two and one-half times as long as eye. Pronotvmi, 

 mesonotum and metanotum smooth, the former with the median transverse 

 sulcus weakly indicated. Abdominal segments elongate, slightly enlarged at 

 their junctures; seventh dorsal segment three-fifths as long as sixth, widening 

 moderately and evenly caudad; eighth al)Out three-quarters as long as seventh, 

 proximad impressed dorso-laterad, not narrowing caudad, lateral margins 

 briefly convex proximad, thence straight, horizontal, the latero-caudal por- 

 tions of the segment vertical with angle sharply rectangulate; ninth (ultimate) 

 segment intermediate in length between seventh and eighth segments, narrow 

 in distal half, strongly cucuUato-tectate, with an appreciable blunt medio- 

 longitudinal carina and lateral surfaces regularly convex, lateral margins con- 

 cave to cereal bases, there forming a blunt obtuse-angulate production, thence 

 to bluntly rounded apex feebly concave, their ventral surfaces thickened, par- 

 ticularly distad, heavily supplied with stout, recurved denticulations. Seventh 

 ventral abdominal segment strongly widened caudad. Subgenital plate (eighth 

 ventral abdominal segment) strongly inflated, with a small blunt conical projec- 

 tion (rounded-triangular in lateral outline) slightly caudad of the median point, 

 from which a minute mcdio-longitudinal carina extends to the evenly convex 

 free dorsal margin. Cerci elongate, cyliiulrical, very feebh^ incurvetl, enlarging 



*^ Thirty-seven new species of this genus are described by Kedtenbacher in 

 the " Insektotifamilie der Phasmiden." Xo figures are given for these, the 

 treatment being fully as unsatisfactory as that of the species of Bostra.
