I may add, that I placed the fly in the genus PaJtostoma on the 
authority of Professor Brauer, of Vienna, who is also responsible for 
the statement^ that a specie^ of that genus has been found on Monte 
Rosa (see Zoolog. Anzeiger, No. 51, p. 134). I have never ventured 
any assumption about the eyes of other BlepJiaroceridce , of which I 
know absolutely nothing ; in the passage alluded to by Baron Osten- 
Sacken, I simply refer to many “other male insects” (“mannchen 
anderer Iverfe ”). 
A full account of the metamorphosis of Paltostoma torrent turn , 
and of the very interesting anatomy of the larva, has been sent for 
publication to the “ Archivos do Museu Nacional do Rio de Janeiro.”

CHARACTERS OF NEW GENERA AND DESCRIPTIONS OF NEW 
SPECIES OF GEODDPdIAGA FROM THE HAWAIIAN ISLANDS. 
BY THE REY. T. BLACKBURN, B.A. 
{Resumed from vol. xvi, p. 109). 
IV. 
The following species, together with examples of most of those 
taken in February, 1878, occurred to me in April and May, 1880> 
during a short visit to Haleakala, Maui. 
The addition of fresh material to my series, and a consequent re- 
examination of the Hawaiian species of Cyclothorax, has led me to the 
conclusion that in my descriptions of C. scaritoides, cordaticollis , 
Deverilli , and vulcanus , the term “ subcordatus ” applied to the pro- 
thorax is misleading, and that “cordatus ” should be substituted for 
it. In a batch of specimens, taken in company, of almost any of the 
Hawaiian Geodephaga , one or two examples will generally be found to 
differ slightly in sculpture from the rest. How to account for this 
fact I know not, but a fact it is ; and, unfortunately, the species 
mentioned above were described on specimens that (I have since dis- 
covered) were not ordinary types. In other respects, however, the 
descriptions may stand.

DISENOCHUS. 
[In characterizing this genus (Ent. Mo. Mag., vol. xv, p. 121), I 
accidentally omitted reference to the eyes. They are only slightly 
convex, and as indistinctly facetted as those of BlacJcburnia insignis 
and blaptoides d\
