70 Capt. T. Broun on new 
shoulders and apices rounded, nearly twice the width of the 
thorax; there are two elongate elevations on each near the 
base and one on top of the posterior declivity, besides some 
smaller ones ; the punctuation is coarse and irregular, but the 
foveiform cavities along the explanate sides are serial. Legs 
maculate. 
This does not closely resemble any other species. Its 
chief characteristics are the rather slender antenne and com- 
paratively inconspicuous nodiform elevations. 
Length 43, breadth 2% lines.

Mr. J. J. Walker, during a recent collecting expedition, 
secured three or four specimens, one of which he placed at 
my disposal. 
Group Gdemeride. 
Thelyphassa fuscata, sp. N. 
Elongate, depressed, infuscate. 
Head finely punctured. Thorax longer than broad, widest 
near the front, gradually narrowed behind, but with the basal 
margin somewhat thickened and prominent ; its punctuation 
is similar to that of the head; near the sides there is some 
fine inconspicuous pubescence.  Scutellum rather large. 
Elytra dull, elongate, with rounded apices ; they are lightly 
but closely punctured and have two indistinct dorsal lines on 
each ; they are covered with fine greyish hairs. 
When compared with 7. diaphana the opaque pale fuscous 
surface first strikes the eye. ‘The thorax lacks the impressions 
and raised central space. ‘The semicircular notch of the 
terminal joints of the male palpi is rather smaller, but deeper, 
and the inner margins are more swollen or angulate beyond 
the middle. 
The apical ventral segment is quite uncovered in both 
Sexes. 
Length 53-6, breadth 14-14 lines.

One pair presented to me by Mr. J. J. Walker. 
Techmessa longicollis, sp. n.

bluish black and with decumbent greyish-yellow pubescence ;
