90 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



scattered localities. The best of the small collections are from 

 the Sierra Nevada de Santa Marta, in the north, on the coast of the 

 Caribbean; from the Cordillera Oriental, in the department of 

 Santander, in the central northern interior; from the valleys about 

 the Cordillera Oriental, in Cimdinamarca, in central Colombia, 

 and from the Cordillera Occidental, in the department of Cauca, 

 western Colombia. Little affinity is shown to the Panamanian 

 fauna by these series, all from regions separated by decided nat- 

 ural barriers, or of widely different character, from low-lying 

 Panama. It is probable, however, that in the lower portions of 

 northern Cauca and eastern coastal Bolivar, the fauna is very 

 similar to that of Panama. Hardly any material whatever is 

 obtainable from the eastern lowlands in the Orinoco and Amazon 

 drainage. 



DERMAPTERA 



PSALIDAE 

 PSALINAE 

 Psalis apolinari- new species (Plate XVI, fig. 1.) 



This insect is apparently closely related to P. peruviana (Bor- 

 mans).^ The present female, when compared with the descrip- 

 tion of the unique male type of that species, is found to have the 

 pronotum much shorter and more nearly quadrate and the tegmina 

 decidedly broader. The caudal portion of the occiput is much 

 paler in the present insect, but this may be due to individual 

 variation. The scent glands are obsolete, the abdomen decidedly 

 broader and the forceps decidedly longer, these features repre- 

 senting possibly only sexual differences. 



The darkened knees and single heavier tooth on each arm of 

 the forceps are striking features in both peruviana and apolinari. 



2 We take pleasure in naming this and other interesting species in the present 

 paper for Hermano Apolinar Maria, Doctor of the Natural Sciences in the 

 Instituto de la Salle, Bogota, Colombia. It is through his kind cooperation 

 that a large portion of the material treated in the present paper has been made 

 available for study.

 p. 505. [cf, Central Peru.] Figured by Burr (Gen. Ins., Fasc. 122, Derniap- 

 tera, pi. iii, fig. 3, (1911) ) as Euhordlia peruviana. This generic assignment 

 is untenable; it was based solely on the fact that the species has rudimentary 

 tegmina.
