that genus. The second and third abscissze of the radius are of almost equal length, the 
apical almost straight; both the recurrent nervures are received before the middle and 
are separated by slightly less than the length of the second abscissa of the radius. Tibial 
and tarsal spines stout, black ; the fourth joint of the hind tarsi is nearly as long as the 
third, it becomes gradually thicker from the base to the apex, which is roundly incised. 
Pygidium closely punctured, covered with a grey pile ; bluntly rounded at the apex, half 
the width there of the base. The mesopleural furrow is deeper and more distinctly 
defined than usual. 
Ichneumonide.

Localities. A single female from Mahé (Cascade) and another from Trou aux Cerfs, 
Mauritius, August, may be this species. 
They have, however, only one horny point in the fore wings, while, according to Brullé, 
rufus has two, or, as he says, “avec une lunule et un point, ou simplement avec deux 
points roux.” I have seen African specimens with one or two horny points; the 
amount of yellow on the head varies. Smith records rufus from Rodriguez. 
22. Hehthromorpha rufo-maculata, sp. nov. 
Head and thorax yellow; a spot covering the ocelli, a large mark in the middle of 
front, united to the ocellar spot by a short line, the centre of occiput, a broad line, 
narrowed at the apex, down the middle of mesonotum, extending from the base to 
the apex, a similar line on the sides on the apical three-fourths, a broad line down the 
middle of metanotum, cne on the upper apical half of mesopleurze, a spot on the sides 
of mesosternum at the apex, and one on the base of metapleure below, black; the 
apex of propleure, base and apex of mesopleurz, the latter broadly below, the sides 
of mesosternum broadly and the base of median segment broadly, rufous; the abdomen 
of a darker reddish colour ; a spot, longer than wide, obliquely narrowed at the base, on 
the sides at the apex of the first segment, narrow, complete, yellow lines on the apices 
of the second and third segments, a similar line on the sides of the fourth, a line on the 
outer third of the fourth ; the base of the third and following segments blackish. Legs 
rufous, the four anterior coxee, trochanters, and underside of femora, the top and bottom 
of hind cox and the underside of the hind femora (broadly at the apex), yellow. Wings 
hyaline, a dark violaceous cloud at the apex, halfway in front of and half behind the 
radius ; the stigma fuscous, the nervures and costa black. Antennze dark brownish 
red, the scape yellow below. 2. 
Length 13 mm.; terebra 4 mm. 
Localities. Seychelles, Coetivy. 
Head smooth, the sides of the face sparsely punctured. Mesonotum closely, strongly 
punctured; metanotum still more strongly and closely punctured, except the black 
line in the middle which is smooth; the scutellums smooth. Propleurz smooth, 
irregularly striated in the middle; the mesopleure sparsely punctured above, more
