162 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



very feebly to the bluntly rounded apices. Limbs simple, cephalic flexiu'e of 

 cephalic femora brief and very decided. Median femora with median carina 

 of ventral surface well supplied with minute chaetiform hairs. ^^ Metatarsi 

 simple. 



Length of body, about 100; head, 4.1; pronotum, 3.2; mesonotum, 24.4; 

 metanotum, including median segment, 15.7; median segment, 9.9; first dorsal 

 abdominal segment, 7.3; cephalic femur, 31.3; median femur, 25; cephalic 

 tibia, 36.6. Width of head at pronotum (least), 2.2; mesonotum (least), 1.8; 

 abdomen at intersection of seventh and eighth segments, 2.9 mm. 



General coloration sepia. Head with dorsal surface tawny olive, paler 

 laterad, with a postocular band of blackish brown on each side, below which 

 the genae are buffy. Abdomen much paler distad, buffy with a few very small 

 markings of black on seventh and eighth and proximal portion of ninth dorsal 

 segments. Subgenital plate dark brown proximad and distad, shading to paler 

 mesad and with a transver.se black spot at the caudal ba.se of the median 

 projection. 



The type is unique. 



We have considered Brunner's treatment of his sub-family Ba- 

 cuneuhnae, in the " InsektenfamiUe der Phasmiden," with sur- 

 prise and dismay. It did not seem possible that so pretentious a 

 work, published as recently as 1906 to 1908, by supposedly the 

 greatest of orthopterists living at that time, could actually be so 

 carelessly executed, superficial and unsatisfactory.^^ Inexcusable 

 ignorance of important literature is shown, publications antedating 

 that work by as much as ten years being wholly or in part ignored. 

 The most important recent literature by Kirby, Rehn and Giglio- 

 Tos has received such treatment. As an instance : of the fourteen 

 Ecuadorean species of the Phasmidae described by Giglio-Tos in 

 1898, three are mentioned. Kirby 's Catalogue, including fixation 

 of all the genotypes, published in 1904, is completely ignored. 

 Selection of single types or genotypes is in almost all cases ap- 

 parently deemed superfluous. 



The new genus Ocnophila, placed among the first genera of the 

 Bacunculinae, is made to include twenty-nine species, many of 

 which when carefully studied will certainly he found to represent 

 distinct generic units. The twenty-five new species are described 



*'' The caudal limbs are missing. 



*' Brunner states that the species of Lihethra can be separated from those 

 of allied genera only by genitalic features. He describes Libethra brevipes 

 from a single female, lacking head and distal portion of abdomen, labelled 

 "Mexico." This kind of work speaks for itself. We would note, however, that 

 the genus Libethra is apparently confined in distribution to northwestern 

 South America.
