514 Mr. E. Saunders’ Descriptions of 
diverging rapidly for one-third of their length, then 
straight to the posterior angles; base slightly bilobed ; 
disk deeply punctured, with an impressed dorsal line, which 
widens considerably as it approaches the base, puncturation 
of the sides deeper. Elytra a little more than twice as 
long as wide, sides subparallel for not quite two-thirds of 
their length, then rounded to the apex, which is denticulate ; 
disk punctured with five longitudinal ridges, between 
which are a few others less strongly raised. Beneath and 
legs largely punctured, covered with very short hairs. 
Length 8 lines; breadth 27 lnes. 
XENOPSIS, N. g. 
Oculi magni; cavitates antennarum minute. Corpus 
cylindricum, nitidum. Hlytra apicibus subtruncatis. 
Tarsi dilati, articulo primo pyriformi, secundo bre- 
viori, tertio et quarto brevissumis. 
Head round,convex in front ; epistome deeply emarginate; 
antennary cavities small; eyes not projecting. Antenne 
with the first jot as long as the second and third together, 
the second being very short, the rest subequal ; becoming 
serrate at the fourth article, the three apical joints scarcely 
so. Body cylindrical ; apex of elytra slightly truncate; pro- 
sternum flat, shehtly swollen in front. Tarsi with the first 
joint pyriform, the second shghtly shorter, the third and 
fourth nearly equal, much dilated and very short. Scutel- 
lum small, somewhat square. 
Closely allied to Castalia, but differmg much in general 
facies, antenne and scutellum. 
Xenopsis levis,n.s. (Pl. XXV. fig. 9.) 
Cupreo-purpurea, punctata, et nigro-pilosa. Hlytra punc- 
tato-striata, apicibus tridentatis. Subtus punctata. 
Coppery-purple, shining with blue reflections. Head 
deeply punctured, covered with recurved black hairs. 
Thorax twice as wide as long, anterior margin straight, 
sides rounded, base straight; posterior angles acute; disk 
punctured, covered with short black hairs. Elytra twice 
as long as wide; punctate-striate, with short hairs; sides 
subparallel, shghtly curved below the middle, apex of each
