Seft. 18^4. J LeNG. On liRVAXIS AI;l)i)MINAI.IS 143 



appears about June first, aiul 1 luive taken C. ///ot/ts/a of tliis brood 

 as late as July fourth. At Curtis Hay, Md., C. ruj^i/to/is appi-arcd 

 as early as March twenty-second. My last specimens of this i)r(H)d 

 were taken May nineteentii, wlien it was less plentiful than in 

 April. When I visited the place ayain on June ninth, 1 could tlnd 

 no trace of either variety. 



.\t the Marylantl locality C. inoJ(sta greatly predominates, 

 while on Long Island I have taken more of C. nii^ifrons than of 

 the black variety. Mr. Beutenmuller informs me that, on Staten 

 Island, C. inodi'sta occurs alone, and is not subject to much variation. 



These varieties seems to prefer sandy ground, where the grass 

 antl weeds are sparse, but do not frecpient bare sanil hills. They 

 fly swiftly, and are rather difficult to catch, especially C. nuhicsta^ 

 which is inconspicuous by reason of its dark color. 



NOTES ON BRYAXIS ABDOMINALIS AuK'. 

 By CuAKi Ks \V. Lf.NC. 



This beetle lives on Staten Islanil under boards, chips etc. 

 cast upon the borders of the salt meadow by tides of unusual height. 

 It is abundant in March and April and occurs also as early as 

 February and as late as May; but the females always outnumber 

 the males. The latter are distinguished by the sculptured dorsal 

 segments. 



I found this beetle first about three years ago under bits of 

 bark lying on the banks of the salt meadow creek which runs 

 beside the railroad trestle west of .Vrlington station. — The ojierations 

 of the railroad company have deepened and elongated a branch of 

 the creek and thereby thrown upon its banks much soil, which lies 

 high and dry above the surrounding moist salt meadow, and affords 

 a lodgement to the bits of refuse and a consequent shelter to the 

 beetles. — While this locality still remains the best, further search 

 has led to the discovery of the species at several other ])oints. 



It is always accompanied by two other species Rhypohius 

 marinus and Scyd/titenus salinator (?).
