This insect appears to be nearest D. chiriquensis Brunner. It 

 agrees in being slender, with hnibs very slender, head and thorax 

 smooth, femora unarmed, apex of abdomen more slender with seg- 

 ments not carinate, ventral margins of eighth^"^ dorsal segment 

 straight and cerci terete with apices incurved. It differs in having 

 the operculum reaching as far as the apex of the eighth dorsal ab- 

 dominal segment, in the apparently more strongly fornicate ninth 

 (distal) dorsal abdominal segment, ^"^ in the shorter mesonotum 

 and metanotum and decidedly shorter femora. Other' features 

 doubtless exist, but can not be determined from the inadequate 

 description of chiriquensis. 



Type. — cf ; San Lorenzo, Sierra Nevada cle Santa Marta, Mag- 

 dalena, Colombia. Elevation, 8300 feet. August 23, 1913. 

 (M. A. Carriker Jr.) [Hebard Collection, Type No. 455.] 



.Size medium for the genus; form very slender; surface smooth, moderately 

 glabrous. Head elongate, very slender, cylindrical, moderately depressed and 

 tapering gently caudad from eyes to pronotum. Eye one-third as long as 

 cheek. Pronotum slender, over twice as long as greatest width, showing faintly 

 the transverse and longitudinal sulci. Mesonotum shorter than cephalic femur. 

 Metanotum with suture of median segment obsolete. Median segment very 

 elongate for genus, two-fifths the total length of the metanotum. AI)dominal 

 segments elongate and slender, distinctly enlarged at their jimctures; seventh 

 decidedly shorter than sixth, widening moderately and evenly caudad; eighth 

 as long as seventh, narrowing caudad, this almost entirely confined to mesal 

 third, lateral outline convex, then very weakly concave, lateral margins briefly 

 convex proximad, thence straight, horizontal, the latero-carudal portion curved 

 briefly inward with angle sharply rectangulate. Ninth (ultimate) dorsal ab- 

 dominal segment appreciably shorter than eighth, narrow, nearly twice as 

 long as broad, cucullate, smooth, not carinate, lateral margins almost straight, 

 feebly convex, ascendant to apical portion which is feebly notched mesad, the 

 small bilobate portion thus formed with ventral surfa(!e of each lobe heavily 

 armed with minute conical teeth. Seventh ventral abdominal segment widen- 

 ing moderately and evenly caudad. Subgenital plate (eighth segment) moder- 



103 Forty new species of this genus are described by Brunner in the "Insek- 

 tenfamilie der Phasmiden." No figures are given and the insufficient and 

 carelessly drawn descriptions are soon found to be even more unsatisfactory 

 than those of Redtenbat^her.
