I may add, that I placed the fly in the genus Paltostoma on the 

 authority of Professor Brauer, of Vienna, who is also responsible for 

 the statement, that a species of that genus has been found on Monte 

 Eosa (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 Kerfe "). 



A full account of the metamorphosis of Paltostoma torrent ium, 

 and of the very interesting anatomy of the larva, has been sent for 

 publication to the "Archivos do Museu Nacionaldo Rio de Janeiro."

CHARACTERS OF NEW GENERA AND DESCRIPTIONS OF NEW 

 SPECIES OF GEODEPHAGA FROM THE HAWAIIAN ISLANDS. 



BY THE EEV. T. BLACKBURN, B.A. 



{Resumed from vol. xvi, p. 109). 



IY. 



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 G. scaritoides, cordaticollis, 

 Deverilli, and vuJcanus, 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. 



ANCHOMENID^E. 

 DISENOCRUS. 



[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 Blackburnia insignis 

 and blaptoides.']
