434 Mr.J.S. Baly on the Classification of the Eumolpide. 
The geographical range of the Myochroine is much more re- 
stricted than that of the preceding subfamily, all the genera, with 
two exceptions, belonging to the American fauna. Glyptoscelis is 
found in North and Central America. The species of Myochrous 
extend from the warmer parts of North America southwards to 
Chili, Columbia’ being apparently their metropolis. Dictyneis, which 
has been hitherto confounded with the genus Myochrous, is exclu- 
sively Chilian. Pachnephorus stretches over a vast geographical 
area,—eight or nine species being natives of Middle and Southern 
Europe, one of Continental India, one or more of the Malay Archi- 
pelago, and two of Southern Africa*. Hryaia is at present found 
only in Africa, the single species on which the genus is erected having 
been sent by the late Dr. Baikie from the banks of the Niger. 
Table of Genera.

B. Winged ; elytra not united at the suture. 
I. Prosternum separated from the episterna by 
sutural grooves.

base and apex, always armed with irre- 
gular teeth sy y.niigise tied. 52 Sees 2. Myochrous.

its episterna, sutural grooves obsolete .... 5. Eryvia. 
Genus DicryNeEis. 
Myochrous (part), Blanch. in Gay's Faun, Chil. 
Apterous. Body elongate or oblong, very convex, often subcylindrical, 
non-metallic, closely covered with adpressed scales or scale-like hairs. 
Head deeply buried in the thorax, perpendicular; antenne long, 
slender, filiform, sometimes slightly thickened towards the apex, first 
joint incrassate, second very short, third equal in length to or longer than 
the two preceding united. Zhorax subcylindrical above, disk forming a 
distinct angle with the ora, lateral margin defined, but without a regular 
border, frequently armed with one or more short irregular teeth. 
* Leconte, in his edition of ‘ Melscheimer’s Catalogue,’ places three North Ame- 
rican species in this genus: the first, 10-nxotatus, Say, belongs to Xanthonia, a 
genus of Adoxine; the two others I do not know, but greatly doubt their being 
true Pachnephori.
