at each extremity, widest at middle; seg- 

 ments five to ten, inclusive, similar in shape, 

 being angular in outline and increasing in 

 width from base to tip; eleventh segment 

 largest, oval, truncated at base. Labrum 

 slightly excavated medially, rounded at 

 sides, with a number of rather strong .';etae 

 arising from its surface, its length contained 

 about 24 times in its width from side to oide. 

 Mandible short, sickle-shaped distallv, its 

 tip acute, its cutting edge very finely denti- 

 culate and provided with a fringe of very 

 fine setae. Lacinia of maxilla with an 

 internal membranous expansion furnished 

 near the tip with a series of rather strong, 

 curved spines and a dense growth of pubes- 

 cence. Galea tapering to tip, also with a 



width of prothorax), its length contained 

 i\ times in width, outline nearly cir- 

 cular. Elytra not quite reaching the first 

 abdominal somite, truncate behind, with a 

 small excavation near outer angle. Wings 

 small and weak, not used for flight as far 

 as observed. Sides of abdomen nearly paral- 

 lel as far as the sixth somite which narrows 

 rapidly to the seventh wliich is small; out- 

 line of somites seen from above nearly 

 square; a groove along each side of the 

 abdomen with a raised outer margin. 



Color pale fulvous. Head darker, some- 

 times nearly black. Three anterior abdomi- 

 nal somites with a transverse black bar a 

 little before the middle. Somites four and 

 five with a larger, more obscui'eh" outlined

dense growth of pubescence distally. Basal 

 article of maxillary palpus very small, cylin- 

 drical; second segment gradually enlarg- 

 ing towards tip where it attains its greatest 

 diameter; third seginent largest, also enlarg- 

 ing from base to tip; distal segment small 

 and slender, gradually tapering towards 

 tip. Prothorax wider than head (width 

 of head about one and a third times in

dark area in place of the bar. These marks 

 are obscure in some specimens, and show 

 best in alcoholic specimens examined with 

 the microscope. 



The species is verv coninioii in some 

 caves, occurring witli Anophthalmiis 

 horni in the tieepest parts. From the 

 charactc-r of the liguhi Mr. E. A. 

 Schvvarz thinks it mav belong to the 

 genus Ocalea instead of Caloder;i.
