lands our knowledge of them is somewhat limited It is from 

 these caterpillars that all our endemic Scleroderinus have been 

 bred. 



SclerodermuE polynesialis Saunders. 



I am unable to distinguish Ashmead's >S'. Perkinsi from this 

 species^ the supposed differences being apparently due to the 

 difference in the conditions of the specimens, the length of the 

 abdomen and the color of the sutures differing with the condi 

 tion of the specimen. 



If my determination is correct this is the species most 

 commonly found on Oahu and has been frequently bred h} 

 the author from wood-boring lepidopterous larvae. I have at 

 hand 19 2 of this species, all but one of which were seeui-ed in 

 the mountains back of Honolulu, one by W. M. Giffard, one by 

 D. T, Fullaway, two by O. H. Swezey and the remainder by 

 the author. I have also a single S bred out with females of 

 this species. A single 9 was taken by Mr. Swezey in lao Val- 

 ley, Maui. The type locality of polynesialis was Mt. Ilalea- 

 kala. Maui. 



The species is quite variable in size. The thorax is dark 

 piceous but the coloration of the insect is such that it seems 

 black considerably darker than any other of the species I 

 have seen from Oahu. 



There is no trace of ocelli in this species. 



Sclerodermus poeci lodes Perkins. 



There are before me two taken in Waialae Xui, Oahu, by 

 Mr. Swezey and two from Tantalus (Bridwell), both lots 

 associated with larvae supposed to be those of Semnoprepia^ 

 in the dead stems of Smilax. 



Sclerodermus kaalae Ashmead. 



There is before me a single 9 which I doubtfully refer to 

 this species in which the head and thorax are piceous, the legs 

 and antennae brownish yellow and the abdomen appears black. 

 The margins of the tergites are testaceous but so closely ap-
