Though it is impossible to state if these cave Psociua belong to Dorypteryx, it is at least prob¬ 
able. I have before me only the imago of Dorypteryx, and the cave Psocina are all nymphce. The 
narrow wing-cases are oval, only a little longer than the thorax, and in younger specimens much 
shorter; all show a little wing still in the cases. The color of the specimens is ivory white, a little 
yellowish (four obscure spots on occiput) on the head; the eyes are in the hind corner of the head, 
large, dark facets, in some convex (as in Olothilla); no ocelli; antennae (only in one seven basal 
joints are present) long, thin; the two basal joints thicker, sh'orter, the following slender, cylin¬ 
drical, long; maxillm trifid at tip; the most external division longest, cut straight at tip, but its 
inner angle bent upward, so that the tip looks pointed; the middle tooth shorter, narrower, 
somewhat ovoid; the third or inner tooth more distant, short, strong, bent outwards. The man¬ 
dibles are large, ending in'a sharp incurved tip, with a tooth before it; the base of both mandibles 
show a strong molar tooth with transverse incisures; the three segments of the thorax narrow, 
separated; feet very long and slender; tibia: much longer than the femur; tarsi three-jointed; 
basal joint long, the following ones short, of equal length; claws short, nearly straight; tip sharp, 
before it one inferior tooth; in some, at least certainly in one fore-leg, three internal teeth are to 
be seen (with a high power); there are no arolia between the claws; abdomen longer, more 
rounded, and ovoid in the apical half. 
The principal difference between the cave specimens would be the wanting of the long mar¬ 
ginal hairs of the wings; but these are only described for the imago , and I have not seen nymphce 
(of Aaron) of Dorypteryx. Of the two specimens found by Mr. Hubbard (l. c., p. 84), I have only 
one before me, and I believe I have returned the other (I think the crushed one is of another lot). 
The specimen before me has three black very faint ocelli, and the eyes more developed as regards 
the facets; but the wings are real nymphce wings, and not, as I have stated (apparently form the 
returned specimen) fastened only to the external corner of the thorax. Otherwise the specimen 
is perfectly similar to those collected by Professor Packard. Indeed all the wings are more like 
those of the short-winged individuals of Termes. I should state that I am not yet sure that 
Dorypteryx and the cave Psocus belong to the Atropina, where the trifid maxilla would place it, 
the more so as the fossil Empheria has similar maxillae. An additional objection is the fact that 
all the cave specimens lose the setae of the antennae in alcohol, whereas Atropina mostly retain 
the setae, especially Hyperetes. The fact that among Atropina occasionally appear ocelli, as also 
in Olothilla (p. 305 Mon. Atrop.), explains their presence in the cave insects. I believe that more 
material alone would give more security as to the position in the system of these cave insects. 
The following list of cave Coleoptera and remarks, with localities, were kindly prepared for me 
by the late Dr, J. L. Le Oonte, and they are printed just as he wrote them. I have added copies 
of the original descriptions and remarks.
