108 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



Type and peculiarities of color pattern very important in present group, but 

 differences due to individual variation must always be discounted. 



Length of body, 25.5; pronotum, 6.7; tegmen, 25.9; wing, 23.9; caudal tibia, 

 8.7; caudal tarsus, 5.8 mm. Width of pronotum, 8.7; tegmen, 7.6; wing, 15 

 mm. 



General coloration ochraceous cinnamon buff, marmorate with tawny ohve 

 and spotted with mummy brown. Head with occiput to interocellar band 

 dresden brown, heavily marked with microscopic dots of mummy brown; 

 ocellar areas and a narrow connecting band ventrad, clouded ochraceous-buff, 

 face below this clouded with prout's brown, in other portions clay color. 

 Pronotum clay color sprinlded evenly and heavily with microscopic dots and 

 a few larger flecks of mummy brown. Tegminal ground color cinnamon buff, 

 marbled with tawny olive, each minute marmorate area becoming darker 

 distad, individually dresden brown to mummy brown, with a heavy fleck of 

 mummy brown mesad in the anal field and a number of such irregular markings 

 mesad on the tegmina. Wings hyaline showing a faint buffy tinge, except 

 from area of costal veins to apex where they are ti'anslucent, suffused briefly 

 proximad with cinnamon buff, the larger remaining distal suffusion tawny 

 olive, all rather thickly flecked with prout's brown. Body buckthorn brown, 

 the abdomen suffused with prout's brown to mummy brown distad. Limbs 

 clay color, the spines and tarsi prout's brown. 



The type is unique. 



BLATTINAE 

 LAMPROBLATTA27 new genus 

 This genus is of particular interest, due to the fact that it 

 probaljly includes the only known American species of the Blat- 

 tinae lacking tegmina of any kind. Furthermore these are the 

 only species of the Blattinae having the dorsal surface smooth 

 and showing this condition. 



The genus includes three species: meridionalis (Bruner),^^ albi- 

 palpus here described, and zamorensis (Giglio-Tos).

 p. 141. [d', 9, Trinidad.] 



The described pair, an additional female and an immature specimen bearing 

 the same data, have been kindly sul)mitted for examination by Professor 

 Bruner. We here select the adult male, in the Bruner Collection, as single 

 type. In addition there is before us an adult male taken at Montserrat, 

 Trinidad, by A. Busck, July 27, from the National Museum. 



Giglio-Tos' Stijlo'pyga zamorensis, described from the valley of Zamora, 

 Ecuador, in BoU. Mus. Zool. Anat. Comp. Univ. Torino, xiii, No. 311, p. 10, 

 (1898), also belongs to the present genus. This is a species differing from 

 albipalpus in its decidedly greater size and differently colored coxae and limbs.
