AMERICAN ORTHOPTERA. 275 



of the eyes, labrum and lower portion of clypeus dull ochraceons; eyes gray- 

 brown ; face blackish. Pronotum with the median portion blackish, the margins 

 reddish ochraceons speckled with blackish. Tegmina ochraceons closely and 

 evenly speckled with rufescent. Abdomen above gray-brown, closely and densely 

 spotted and blotched with dull blackish brown; ventral surface of abdomen with 

 the median portion of the basal segments gray-brown, the remainder pitch-brown. 

 Limbs dull ochraceous brown marked with umber. 



Measurements : 



Length of body, ...... 21. mm. 



Length of pronotum, ..... 6. " 



Posterior width of pronotum, .... 8.1 " 



Length of tegmina, ...... 5.5 " 



Greatest width of tegmina, .... 5. " 



Three topotypes, all females, have also been examined. One speci- 

 men is immature, and has the tegmina and wings undeveloped, but 

 otherwise is much like the type. The coloration varies considerably 

 in the series, but is mainly in the intensity. One specimen is very 

 light and has the characteristic lyrate Epilamproid pattern on the 

 pronotum distinctly visible, while in the type this is hardly dis- 

 cernible. 



I have dedicated this species to my friend, Mr. Hamilton, who 

 collected the specimens examined, while attempting the ascent of 

 Torquino. 



< alolampra cicatricosa n. sp. 



Type: 9; San Carlos, Costa Rica. (Schild and Burgdorf.) 

 [Cat. No. 6940, U. S. N. M.] 



Allied to C. gracilis Brunner* from Australia, but differing in 

 the completely hidden head, the punctate front, the broader supra 

 anal plate, the slightly emarginate subgenital plate, the longer meta- 

 tarsi of the posterior limbs, and in the larger pronotum. Some rela- 

 tionship appears to exist with C. aptera Schulthessf from Northeast 

 Africa, which is however a quite different insect. 



Size medium; form depressed ovoid, apex anterior; surface finely cribrose. 

 Head completely hidden under the pronotum ; interspace between the eyes 

 considerably greater than that between the ocelli ; eyes strongly compressed, the 

 greatest depth anterior; antenna? short, not equalling half the length of the 

 body ; ventral surface of the head with the surface strongly cribrose. Pronoturu 

 produced hemispherical in outline, the anterior margin rounded, the posterior 

 subtruncate, slightly sinuate toward the lateral angles which are rect-acute. 

 Meso- and metanotum with their posterior margins concave, slightly produced
