PACHYCORIS, Burm. 
1. P. Wilsonii, n. sp. 
Rather less robust than P. niteiis Dallas, the scutellum subtruncated 
at tip, and oblique each side before the tip. Head blue-black, with a 
large yellow patch on each side of the tylus, upon which the punctures 
are few and obsolete the lateral margins recurved almost to the eyes, 
very slightly sinuated. Thorax violet, or blue-black, the punctures 
minute, remote, sides almost straight, the margins broadly recurved, 
the surface with eight orange spots, which are a little longer than in 
P. nitens, those of the anterior angles run along the lateral margins to 
beyond the middle, the post-humeral ones reaching the base of the 
scutellum. Scutellum with fourteen large orange spots, arranged 5, 4, 
3,.2, punctured like the thorax. Pectus with large transverse yellow 
spots near the coxae, and the lateral spots of the upper surface dis¬ 
tinctly exhibited upon it. The first ventral segment, and a long trans¬ 
verse spot each side of the remaining segments orange. Legs steel 
blue, more or less orange at base. 
Length 10-11 millim. Humeral breadth 7-71 millim.

It varies very much in coloring, and one of the varieties offers the 
same style of coloring as is met with in the yellow variety of P. K/ugii, 
Burm. 
I desire to dedicate this species to Dr. T. B. Wilson, as a slight tes¬ 
timonial of the high esteem in which I hold the many kind assistances 
that he has extended to me in my studies of the Hemiptera of this 
country. 
2. P. Stallib n. sp. 
Form and general appearance of P. nitens, Hope, but polished deep 
black, or slightly tinged with purplish, above very minutely scabrous, 
more coarsely, closely, deeply punctured ; tylus much longer than the 
lateral lobes, the head not so acutely narrowed at tip, the lateral mar¬ 
gins not recurved. The spots orange-red, small, ovate, arranged simi¬ 
larly to those of P. nifenSj but two less in number (those of the humeri 
being wanting), and the spot of the anterior angle placed near the middle 
of the lateral margin and elongate-oval in form. Lateral margins of the 
thorax a little more strongly?- recurved, against this the depressed sub¬ 
margin is densely punctured. Posterior margin of the scutellum dis-
