OPEIA. 61 



6. Opeia palmeri, sp. n. 



A brachypterous, moderately robust species, in which the prevailing colour is brownish-testaceous, varied by 

 longitudinal brown bands. 



Head very slightly broader than the front edge of the pronotum, the occiput on the same plane as the disc of 

 the latter ; eyes not at all prominent, a little longer than ( $ ), or about equal to ( $ ), the length of the 

 portion of the cheeks below them ; vertex provided with a gently raised border and a well-defined median 

 carina, the lateral edges scarcely foveolate, and meeting at the fastigium in a right angle in the female or 

 in an obtuse angle in the male. Antennas with the basal joints considerably flattened in both sexes, but 

 scarcely ensiform even in the female, as long as the head and pronotum together in the male, about 

 reaching the last transverse sulcus in the female. Frontal costa of medium width and gradually broad- 

 ening below, sulcate in the male, nearly plane in the female. Face when viewed from the side not very 

 oblique, less so than in 0. obscura and 0. testacea. Pronotum a little wider behind than in front, the 

 lateral carinas evenly converging in the female, parallel from the principal sulcus in the male, but 

 divergent on the posterior lobe. Tegmina about half as long as the abdomen, acuminate, and with their 

 dorsal edges slightly overlapping. Hind femora broad on the basal two-thirds, slender beyond ; tibiae 

 with 10 spines on the outer row. 



Sides of the head and the upper half of the sides of the pronotum provided with a gradually broadening brown 

 band. Disc of the tegmina with a row of small quadrate dusky dots. Upper edge of the outer face of 

 the hind femora also dark. In the single female specimen at hand the median carina of the pronotum 

 and a narrow median line on the occiput to the fastigium are dark brown. Tips of the antennas and feet 

 a little darker than the general colour. 



Length of body, S 15, $ 20 ; of pronotum, <$ 3, $ 4 ; of tegmina, tf 6, $ 7 j of hind femora, tf 10,

 One male and one female. 



7. Opeia lineata, sp. n. 



Large and robust for the genus to which it belongs ; much varied with light and dark lines. The tegmina 

 greatly abbreviated and with the dorsal edges not touching. 



Head moderately large, about as wide as the front edge of, and nearly as long as, the pronotum ; the occiput 

 smooth, evenly rounded ; vertex about as wide as the shortest diameter of the eyes, roundly depressed, 

 the antero-lateral carinas blunt, with the surface just inside gently sulcate, furnished with a blunt longi- 

 tudinal median carina, which becomes nearly obliterated about midway to the front edge of the pronotum. 

 Face only gently oblique, the frontal carina broad, shallow, sulcate, evenly expanding downward, reaching 

 the clypeus, its lateral walls coarse. Eyes subpyriform, about as long as the portion of the cheeks below 

 them, not prominent. Antennas acuminate, short. Pronotum slightly widest behind, gently compressed 

 at the middle, the lateral carinas gradually approaching anteriorly, the transverse sulci dim, the last cutting 

 all three carinas, situated about one-third the distance from the hind edge, the latter scarcely angulate. 

 Tegmina short, acuminate, reaching the apex of the third abdominal segment, their dorsal edges not 

 attingent. Hind femora rather robust, as long as the abdomen. 



The general colour of the single specimen at hand is light testaceous, much varied with dusky streaks. 

 Occiput provided with a broad, median, longitudinal light band that extends from the fastigium to the 

 posterior edge of the pronotum, bounded on either side by one of black, the latter about one-half the 

 width of the former. Lateral carinas of the pronotum light-coloured and continued on the head as a 

 narrow testaceous stripe to the posterior edge of the eyes ; below this there is a narrow black line, 

 followed by a rather broad infuscated area, then a light one, and again a second dusky one. Lower edge 

 of the pronotum and cheeks broadly testaceous. Lateral facial carinas light-coloured, bordered very 

 narrowly with black. Sides of the pronotum just behind the last sulcus and midway from the top to 

 the bottom provided with a short, raised, smooth, white ridge. There is also a narrow, black-bordered, 

 dirty-white line on each side of the head behind the middle of the eyes. Pleura streaked with light and
