their lower edge and terminating in an acute apex. Hind tibiae and tarsi hirsute, the former eight- 

 spined on both margins, the latter with the joints successively longer. Prosternal spine robust at base, 

 terminating in a short acuminate nipple. Cerci of male robust, the sides nearly parallel, a little longer 

 than broad, the apex sinuately truncate. Valves of the ovipositor short, the apex profoundly hooked and 

 the outer edges of the upper pair strongly crenulate. 



Colour of the anterior and middle legs, together with the abdomen, dark olivaceous ; face and lower border of 

 cheeks black ; antennas with the basal joints pale, gradually darkening towards the middle, where they 

 are black, the two apical joints testaceous. Occiput in middle black, at sides pale olivaceous. Pronotum 

 in the middle of the disk, and on the lower edge, as well as on the upper portion of the sides, longitudinally 

 vittate with shiny black and pale olivaceous, the pale vittae placed on the middle of the sides and at the 

 outer border of the disk, there being four of the latter and five of the former, all of which continue upon 

 the tegmina. Hind femora strongly tinged with red on the basal two-thirds and dimly bifasciate with 

 black, beyond annulate with flavous in advance of the ferruginous genicular area ; the tibiae olivaceous 

 basally, strongly infuscated on the apical two-thirds, the tarsi dark olivaceous. Labrum and region about 

 the base of the middle coxa? ferruginous.

Eab. Costa Rica, Pozo Azul (M. A. CarriJcer). 



The most characteristic feature of T. femorata is its very large, robust, reddish 

 hind femora.

It is quite possible that this species is also to be met with in the southern part of 

 Costa Rica, Chiriqui, or Panama.] 



5. TaBniophora megacephala, sp. n. 



As indicated by the synoptic table, the present insect is most closely related to the preceding species, from 

 which it differs in the absence of pale vittae on the head, pronotum, and tegmina. It also lacks the prae- 

 apical pale annulus of that species, and has the genicular region of the hind femora black instead of 

 sanguineous. The whole insect is strongly tinged with smoky brown and piceous. 



Head unusually large, the occiput swollen and greatly elevated above the plane of the pronotum ; the eyes 

 fairly prominent and separated above at the vertex by a space fully as broad as the diameter of the rather 

 large basal joint of one of the antennae ; the front sparsely, coarsely punctate. Occiput and pronotum 

 also coarsely and profoundly punctate ; the latter with the front edge strongly and widely bordered or 

 margined, the hind margin of the disk very broadly angulate. Tegmina about two-thirds as long as the 

 abdomen, their apex rounded, the discal area paler than the remaining portion, which is dark piceous. 

 Hind femora slender, without bands, but somewhat paler basally ; the tibiae and anterior and middle legs 

 piceous, as is also much of the face and pectus. 



Abdomen testaceous, showing traces of smoky brown. Valves of ovipositor as described for T. femorata. 



Length of body, $ , 16 ; of pronotum 3*35, of tegmina 7"5, of hind femora 10 millim. 



Hab. Panama (coll. S. H. Scudder). 



The single specimen examined has the antennas broken off. It differs from 

 T. femorata and the other described species by the decidedly wider vertex.
