Sept,igc6.] Bruner : The Orthoptera of Trinidad. 141 



19. Epilampra brevis Brunner ? 



There are a like number of a second species from the same locality 

 and person which seem to belong to Brunner' s E. brevis. 



20. Blatta (Stylopiga) meridionalis, new species. 



A medium-sized species of glossy black color in which both sexes are entirely 

 apterous, not showing even the slightest signs of the aborted lateral tegmina as figured 

 for insularis. The distinguishing characteristic of the species, however, is the dirty 

 white palpi, which are very conspicuous in comparison with the otherwise general 

 pitchy black color of the insect. 



In size this cockroach is somewhat smaller than orientalis. It is also more 

 compactly built and darker colored, while its entire body is smooth and impunctate. 

 The only variation from the general black color, except the palpi as indicated above, 

 are the antenna' on their apical half, the legs on their coxie, the front edge of the 

 femora, the knees and parts of the tarsi which incline to rufo-piceous. The legs are 

 quite strongly spined. The spines on the posterior edge of the anterior femora both 

 above and below are much smaller than those on the other legs, the number fourteen 

 or fifteen in each row. The middle and hind pairs have this part provided with a 

 series of seven both above and below. The apical dorsal segment or supraanal 

 plate of the £> abdomen is triangular with its tip evenly rounded, while the last ven- 

 tral is prow-shaped and pointed. In the $ the upper plate is slightly transverse 

 with rounded lateral edges and a slight longitudinal median furrow which gives to it 

 a somewhat bilobed appearance. The cerci are moderately long and robust in both 

 sexes. 



Length of body, d\ 16, 9, 23 ; of pronotum, d\ 4, 9, 5-4o ; 

 greatest width of pronotum cJ\ 6, 9, 7 millimeters. 



Habitat. — Island of Trinidad, 1 (?, 1 ? (H. D. Chipman, col- 

 lector). 



The types are in the author's collection. 



21. Periplaneta americana Linneus. 



This cosmopolitan species is represented by several specimens. 

 It was also collected by Mr. Chipman, presumably in Port of Spain. 



22. Periplaneta australasise Fabricius. 



Likewise from Port of Spain. Taken by Chipman. Like the 

 preceding a cosmopolitan insect, but more especially confined to the 

 warmer parts that are visited by ocean shipping. 



23. Leucophaea surinamensis Linneus. 



There are also several specimens of the above-named cosmo- 

 politan roach. They come from Mr. Chipman and were taken in the 

 interior of the Island of Trinidad.
