Mast. Cat. Col. Sp. 2500. 
The collection contains two fine specimens of this insect, the 
first I have ever seen. 
178. Cryptodus Fairmairei, n.sp. 
I name the present species after Mr. Fairmaire, who has written 
the most complete monograph on this genus I have seen. It has 
a considerable resemblance to G. variolosus, White, from King 
George’s Sound, but differs in being of slightly more elongate 
form, in being of a blacker colour, in the minute tubei’cles on the 
forehead, in the thorax less transverse, more densely punctate, 
and more distinctly depressed on the median line, in the elytra 
more square at the humeral angles, more parallel-sided, and more 
elongate, with the variolose punctures more crowded and less 
deep, with the costae less distinct, and the small punctures spread 
throughout much smaller and denser. 
Sub-Family CETONIIDES. 
179. Hemipharis Froggatti, n.sp. 
Of more elongate form than H. insularis. Entirely golden 
green. Head punctate. Thorax smooth, slightly scratched and 
punctate on the lateral margin. Elytra also smooth, a little 
transversely scratched at apex and sides, narrowing to the apex 
more than in II. insularis. Pygidium transversely scratched. 
The undersurface almost witliout punctu ration. 
Long. 11|, lat. 5 lines. 
180. Dilociirosis tourida, Jans. 
Mast. Cat. Col. Sp. 2549. 
181. Polystigma vitticolle, n.sp. 
The genus Pohjstifjina is one of the many into which Dr. Kraatz 
has cut up the old genus Schizorhiva. It includes the 6'. punctata
