PLIAZURUS. 13 
of the third elytral interstice, the broad, transverse, arcuate, black fascia on the 
prothorax, and the saddle-shaped black fascia below the middle of the elytra, the 
outer portion of this latter usually extending forward to the shoulder. The apex of 
each elytron is produced into a rather long tooth, the intervening space being truncate. 
The second joint of the funiculus is a little longer than the third. The length varies 
from 83-14 millimetres. The var. y appears to be distributed in collections under 
the MS. name P. ¢ransversus, Faust. 
4, Piazurus spretus, (Tab. I. fig. 22.) 
Piazurus spretus, Heller, Stett. ent. Zeit. 1906, pp. 33, 39’. 
Subrhomboidal, black, the antenne and the tips of the tarsi ferruginous ; the head with an ochreous line 
around the eyes, and the prothorax and elytra with numerous small, similarly-coloured spots, the rest of 
the vestiture of the upper surface uniformly dark brown, that of the under surface and legs close and 
cinereous, the femora faintly annulate. Head densely, minutely punctate, the eyes subcontiguous ; 
rostrum densely punctate and carinate at the base, and almost smooth thence to the tip; joint 2 of the 
funiculus a little longer than 3. Prothorax strongly transverse, subconical, constricted in front, deeply 
sinuate at the base; densely, minutely punctate and sometimes obsoletely carinate. Elytra very much 
wider than the prothorax, rounded-triangular, the humeri swollen, but not prominent, the apices rather 
sharp, obliquely truncated ; punctate-striate, the interstices minutely punctate, more or less convex, 
except at the tip, 3 with an oblong prominence at the base. Beneath closely, very finely punctate, the 
depressed space down the middle of the first ventral segment smoother, the fifth segment slightly sinuate 
at the apex in the ¢. 
Length 93-123, breadth 44-64 millim. (¢ 9.) 
Hab. %Guatemata (Mus. Brit.); Nicaragua (Sallé'), Chontales (Belt, Janson, 
Richardson). 
We have received eleven specimens of this species from Nicaragua. It may be 
easily recognized by the numerous small ochreous spots on the upper surface, and the 
rather convex elytral interstices, the third with a conspicuous prominence at the base ; 
the elytral spots are mostly divided by the strie. 
5. Piazurus heileri, sp. n. (Tab. I. figg. 23, 23 a.) 
Subrhomboidal, black, the antenne and the tips of the tarsi ferruginous; the head with a line around the 
eyes, and the prothorax and elytra with various small scattered spots, cinereous or ochreous, the rest of 
the vestiture of the upper surface uniformly dark brown, that of the under surface (a broad almost 
smooth space down the middle excepted) and legs close, cinereous or flavo-cinereous, the femora fusco- 
annulate. Head densely, minutely punctate, the eyes subcontiguous; rostrum carinate and closely 
punctate at the base, and almost smooth thence to the tip; joint 2 of the funiculus considerably longer 
than 3. Prothorax transverse, conical, feebly constricted in front; densely, minutely punctate. Elytra 
very much wider than the prothorax, rounded-triangular, transversely depressed below the base, the 
humeri swollen, the apices rather sharp, obliquely truncated; finely striate, the striz with scattered 
punctures, the dorsal interstices flat, 3 with a large conical tubercle below the base. Beneath closely, 
finely punctate, smoother and almost bare down the middle; ventral segment 1 broadly sulcate, 5 sinuato- 
truncate at the apex in the ¢. 
Length 10-12, breadth 53-63 millim. (¢ 2.) 
Hab. GUATEMALA, Panzos in the Polochic Valley (Champion) ; Nicaragua, Chontales 
(Belt, Janson).
