140 Schiodte s Specimen 



the first joint in the tarsi of all the legs not longer than the fol- 

 lowing. 



The two species resemble each other much, but may be easily 

 discriminated by the structure of their antennae and labial palpi. 

 In the smallness of their size and their habit they resemble the 

 Ptilia, having the same darting motion, which is exceedingly 

 rapid. I met with a number of specimens of Bathyscia byssina 

 in the inner part of the Adelsberg cave, occupying the small 

 clusters of Byssus fulvus, on the short and stinted columns. The 

 other species, B. montana, is common in the Luege grotto, among 

 loose earth and little stones along the walls ; but I have found 

 it also, and in far greater quantities, among moist leaves in 

 forests, on shady rocks near the castle Veldes, on the Carniolan 

 Alps. I examined this species anatomically during my stay at 

 Veldes ; but as we do not possess more than the few observations 

 I published some years ago* respecting the internal structure 

 of Choleva and Colon, with which Bathyscia is to be compared, 

 there is no need of my saying more on the subject for the pre- 

 sent, except that Bathyscia agrees with these genera in the cha- 

 racteristic want of a ccecum, but differs strikingly in the following 

 points : the malpighian vessels have the same angular nerve and 

 thickened end as that which, on another occasion, f have been 

 pointed out by me as characteristic of some families of the divi- 

 sion of clavicorn beetles ; the pair of spermatic vesicles are short, 

 wide and clavate, not long and rolled up ; the testicular vesicles 

 are small and very numerous, and they form together a globular 

 body. 



As yet it is doubtful what relation Bathyscia has to Tellkampf 's 

 genus Adelops. According to the character he gives of this form, 

 it differs from Choleva only by its want of eyes, and would accord- 

 ingly belong to that genus, provided his account is correct, and no 

 essential character has been omitted. The similarity of locality, 

 and the analogy existing between the European and North Ame- 

 rican Fauna, which, as far as regards cave-animals, is strikingly 

 exemplified by the similarity between the Anophthalmi of these 

 two countries, would seem to indicate that Adelops ought to 

 merge into Bathyscia. This supposition is somewhat supported 

 by Tellkampf's figure, in which the first joint of the feet is repre- 



lation to the upper lip, as the supplementary tongues [paraglossae] have to the 

 under lip, certainly can have no application as far as regards the Silphide, where 

 it is clear that both lobes are simply a continuation of one single organ.
