Habitat. — i ? and perhaps also a $ nymph, Island of Trinidad, 

 West Indies, collected by H. D. Chipman (Coil. L. Bruner.) 



49 Paurotarsus rugosus, new species 



Rather robust and with the surface of pronotum and head above more than com- 

 monly rugose, the rugte on disk of former appearing as numerous blunt longitudinal 

 ridges of varying length. The sexes not greatly unequal in size. 



Head short and broad ; eyes rather small and separated above by a space a little 

 wider than their greatest diameter ; vertex broadly convex, very rough, notched later- 

 ally at middle of eyes, considerably advanced in front, provided in the middle with a 

 prominent carina, the antero-lateral edges rounded and provided with well-marked 

 carinse, which, however, do not reach the middle in front. Frontal costa very promi- 

 nent and broad, the lateral edges heavy and rather profoundly divergent below, sili- 

 cate from the extreme vertex. Lateral facial carina strong, arcuate, extending from 

 the base of the antennce to lateral edges of base of clypeus. Lateral ocelli very 

 prominent, situated above the middle of inner edges of eyes and against the sides of 

 frontal costa. Antenna; filiform, 18- or 19-jointed, about reaching the base of teg- 

 mina, situated a trifle above a line drawn from the lower edge of eyes, the basal joint 

 rather large. Posterior lateral angle of pronotum not at all produced, the lower and 

 posterior edges meeting in a right-angle. Antero-dorsal process of pronotum not ad- 

 vanced upon the occiput ; in both sexes extending slightly beyond the tip of the hind 

 femora, the latter slightly surpassing the apex of abdomen ; tip of male abdomen long 

 and tapering, apex of last ventral segment rather deeply notched ; valves of ovipositor 

 long and wedge-shaped, rather strongly serrate. Hind femora large and course, 

 somewhat longer in proportion to the size of the insect than usual in members of the 

 TettigiiKu. 



General color dull brownish black, more or less varied on pronotum above and 

 on the legs with dirty ferrugineo-testaceous — the venter irregularly mottled with tes- 

 taceous, the valves of ovipositor pale with darker apex. 



Length of body, i', 11 mm., + , 13 mm.; of pronotum, r? 

 11 mm., 9, 12.5 mm.; of hind femora, tf, 6.5 mm., ?, 7.25 mm.

Subfamily Eutryxalin.e. 



50. Eumastax sp. 



A single nymph of a species of Eumastax was collected and sent 

 to me by G. E. Tryhane, of St. Anne's. It seems to be most closely 

 related to the E. plebja Gerst., but in the absence of mature speci- 

 mens cannot be definitely determined.
