XXII. ANOPHTHALMUS Sturm. 1844. (Gr., "without eyes.") 



Small, pale brown, eyeless beetles found in caves. Eight species 

 are known from the United States, two of which were described 

 from Wyandotte Cave, Indiana. For literature see:

Elongate, slender. Pale brownish-yellow, shining. Head 

 oval, front with two curved impressed lines. Thorax broader 

 than head, slightly longer than wide ; sides curved in front, 

 \_ sinuate behind, median line distinctly impressed ; hind 

 angles rectangular, acute. Elytra elongate-oval, two-thirds 

 longer than broad, surface finely alutaceous; stri.e faint but 



evident, with three bristle-bearing punctures along the third.

(After Packard.) Length 4.5-b mm. (Fig. 56.) 



Caves of Monroe, Lawrence and Crawford counties; frequent in 

 Wyandotte. April 15-September 20. They occur only in the re- 

 mote parts of the caves, where they may be found crawling rapidly 

 over mud, sand or rocks in damp localities. Like other Carabids, 

 these small blind beetles are supposed to be carnivorous. In Wyan- 

 dotte specimens of mites, spiders, springtails and harvestmen were 

 taken in the same locality as the beetles, and probably furnish the 

 latter a scanty supply of food. 



119 (491). ANOPHTHALMVS EREMITA Horn, Trans. Amer. Ent. Soc.. III. 

 1871, 32S; (irol. Surv. Ind., 1X72. 180. 



Of the same color as ten nix and resembling that species but broader. 

 Thorax wider than long and wider than head : hind angles less prominent. 

 Elytra more distinctly alutaceous, with scarcely any traces of stria?, the 

 surface subopaque. Length 5 mm. 



Very rare ; originally described from a single male specimen 

 taken in Wyandotte Cave, Crawford County. The type is in the 

 Horn collection at the Philadelphia Academy of Natural Sciences. 



Tribe VI. I'TEUOSTICHINI. 



Beetles of medium or large si/e. having the antenna? arising from 

 beneath a distinct frontal ridge, the three basal joints glabrous; 

 mandibles without a bristle-bearing puncture in the outer groove; 

 mentum broad, usually deeply emarginato and toothed. Thorax 

 with at least one bristle-bearing puncture at side and one at hind 

 angle. Body not pedunculate, scutellum distinct. Elytra narrowly 

 indexed, margin strongly interrupted behind the middle and with
