VII. 
THE GENERA OF ORYID^. 
This family is divisible into two subfamilies, the Oryini, having the 
spiraculiferous scutellum coalesced with its prescutellum, and the 
Orphnaeini, in which there is a distinct prescutellum usually larger 
than the somewhat triangular spiracle-bearing sclerite. In the Oryini 
the part in question is large and rectangular, as long as the tergites 
and conspicuous to the naked eye on account of the large size of the 
forms which compose this subfamily. The Oryini comprise two 
closely related genera, Orya, from the western part of the Mediterra- 
nean basin, and Parorya *, a new genus from Texas which may be 
distinguished from”air^merican members of the suborder by the 
characters mentioned. Moreover it is the most robust of American 
Geophiloidea. From Orya it differs in the much slighter development 
of the presclerites throughout the body, which is shown most strik- 
ingly in the anal (apodous) segment where the presternite is rudimen- 
tary in the female, while very distinct in Orya ; the spiracle-bearing 
scutella are also not as prominent in their anterior part as in Orya, 
where on anterior segments, especially, the lower corner in front is 
produced so that the spiracle appears to be located in a deep notch. 
The spiracles of Parorya are much longer and narrower than in the 
European genus. Both genera have the mouth-parts, anal legs and 
pleurae much the same, though more secondary sexual characters may 
appear when males of Parorya are examined ; the only feature of this 
kind to be noted at present is that in Parorya the apical joint of the 
genital palpi of the female, though small, is quite distinct, while in 
Orya it is reduced to a mere rudiment. 
The genera of Orphnseini are more numerous and somewhat more 
varied among themselves ; all are more slender and less depressed 
than the Oryini. No satisfactory examination of the mouth-parts 
and ventral pores has been made, but these are much alike in all the 
forms dissected, as should be the case in members of the same family. 
Diagnoses of these genera have been arranged as follows : 
Pairs of legs i6i or thereabouts ; spiraculiferous scutellum much smaller 
than its prescutellum ; two rows of long suprascutella, the lower broad, the 
upper narrow ; claw of maxillary palpus not pectinate ; frontal lamina not dis- 
* Based on g new’’ species with 113 segments, 120 mm. long when 
contracted in alcohol, and nearly 6 mm. broad : its locality is not definitely 
known, but it is probably from Texas, as it was among a collection made by 
Shufelt in Louisiana and Texas.
