104 Mr. C. O. Waterhouse on the 
insect which I suppose to be H/. parallela of Motsch., 
from the above diagnosis (given in the Etud. Ent. 1854, 
p- 64), differs from H. picea in haying the head less 
thickly and less rugosely punctured; the neck is finely 
punctured and is not separated from the forehead by any 
distinct line; the thorax is the same form, but is rather 
less thickly and more strongly punctured; the margins are 
very slightly crenulate and have only short hairs; lastly, 
the raised stria next the suture, which in both becomes 
very dilated posteriorly, never unites with the suture, 
whereas in //, picea it approaches and nearly joins the 
suture some distance before the apex. In both species 
the tarsi are longer in the males.

Holotrichia morosa, sp. nov. 
fH. picee persimilis, at fere nigra, tota pruinosa, con- 
vexior. 
Long. 10 lin. 
This insect only differs from H. picea in being more 
convex, nearly black, and opaque through the pruinose 
surface. The club of the antennz is very small, not 
longer than the four preceding joints taken together, 
whereas in /Z. picea the club is nearly as long as the six 
preceding joints. 
I at first believed this to be the 2 of HZ. picea, but from 
dissection this is evidently not the case.

folotrichia castanea, sp. nov. 
H, sinensi affinis. Oblonga, castanea, elytris nitidis. 
Capite lato, confertim punctato, clypeo leviter emarginato, 
fronte transversim carinaté. Thorace convexo, antice 
paulo angustato, longitudine 3 latiori, margine antico vix 
emarginato, angulis anticis obtusiusculis, lateribus arcu- 
atis, angulis posticis obtusis, fere rotundatis, superne con- 
fertim subtiliter punctato. Scutello confertim punctato. 
Elytris thoracis latitudine postice paulo ampliatis, ad 
apicem rotundatis, crebre fortiter punctatis, sutura late 
paulo elevata. 
Long. 93 lin.; lat. 5 lin. 
Closely allied to H. sinensis, Hope, but that species 
has the thorax and base of the elytra blackish. The sides
