84 Mr. J. O. Westwood’s Descriptions of 
Platyrhopalus fVestwoodii, mihi. Plate X. fig. 5. 
Castaneous . — Antennce about two-thirds the length of the head 
and thorax, the terminal joint very large, nearly lenticular, 
slightly hirsute, with a pointed production at the base ex- 
teriorly. Head somewhat orbicular, nearly as broad as the 
thorax, darker posteriorly, the eyes projecting. Thorax 
cordate, slightly hirsute, with three transverse impressed 
lines across the base, dark-castaneous, the anterior angles 
lighter. Elytra twice the breadth of the base of the thorax, 
half as long again as broad, slightly hirsute, with a large tri- 
angular black spot on each elytron at the base ; another large 
somewhat semicircular discoidal one about the middle, and 
a third small lunular one at the apex. Abdomen projecting 
slightly beyond the elytra. Legs moderate, stout, with the 
knees black. 
Length seven-twentieth of an inch. 
Obs. — This very fine species was kindly presented to me by 
Sigismund Rucker, Esq., jun., who purchased it in a collection of 
insects from the East Indies. I have named it after our most 
indefatigable Secretary, whose Monograph on the Paussidce in the 
Linnaean Transactions, will ever be a memento of his great skill 
and exertions in the science of Entomology, and in the present 
instance I have to thank him for the two excellent figures which 
accompany these two descriptions.

Since the publication of my Monograph upon the Paussidce , 
in the 16th volume of the Linnaean Transactions, l have ob- 
tained a knowledge of several new r species of this extraordinary 
group of beetles, and also gained a more perfect acquaintance 
with others, which, at the period when this Monograph was written,
