*2305 (7402). HAPLANDRI s FEMOKATUS Fab.. Syst. Eleut.. I. 1801, 154. 



Oblong-oval. Piceous. opaque ; femora reddish-brown. Third joint of 

 antenna- longer than fourth, twice as long as second. Thorax nearly square, 

 sides almost parallel, angles rectangular: surface. :.s \vell as that of head, 

 densely and continently punctate. Elytra each willi one scutellar and eight 

 entire rows of elongate, deeply impressed punctures. Length 7.5-11 mm. 



Throughout the State, but scarce. Occurs beneath bark and logs, 

 especially in sandy localities. Hibernates. January 13-December 

 7. H. conc.olor Lee., having the third joint of antenna 1 short, legs
