148 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



band of green. Abdomen with dorsal surface black, lateral margins of seg- 

 ments and caudal margin of distal segment greenish. Entire ventral surface 

 of insect green. Femora civette green, distad lined with black dorsad and 

 laterad, these lines broadening distad. Cephalic tibiae black, median and 

 caudal tibiae suffused green, black dorso-distad. Cerci and tarsi black, the 

 hairs yellowish. 



The type of this strikingly beautiful insect is unique. 



HOLCOIDES new genus 



The present genus is readily separable from others of the 

 Stratocles Section of the Phasmini by the femora and tibiae all 

 being terete, both dorsad and ventrad. In Redtenbacher's key 

 the genus would stand nearest Para stratocles. 



Genotype. — Holcoides forceps new species. 



Description of Genus. — Head elongate, nearly twice as long as 

 width between eyes; ocelli distinct. Antennae elongate, segments 

 increasing greatly in length distad, the very elongate distal seg- 

 ments divided into numerous joints. Head, pronotum and meso- 

 notum smooth. Mesonotum shorter than metanotum; with a 

 decided medio-longitudinal sulcus in slightly less than proximal 

 half, which is bounded laterad by rounded carinae; lateral mar- 

 gins strongly cingulate. Tegmina short, truncate. Wings fully 

 developed. Male disto-dorsal abdominal segment highly spec- 

 ialized. Mesosternum evenly convex in transverse section. 

 Cephalic femora with cephalic flexure distinct. All femora and 

 tibiae terete both dorsad and ventrad. 

 Holcoides forceps new species (Plate XXI, figs. 2, 3 and 4.) 



This species is of particular interest in showing not only an 

 unusual type of limb structure, but also distinctive male genitalia 

 features. 



The general appearance of the insect agrees very closely with 

 that of Holca annuUpes Redtenbacher^^; that species differing 

 widely, however, in the carination of the femora, sulcation of the 

 cephalic; tibiae, the percui'i'ent sulcus and gramilation of the 

 mesonotum and Ijlack radial vein of the tegmina.
