H. C. FALL. 39 



LIXUS Fab. 

 L. inaritiinus n. sp. — Rather slender, parallel, black, slightly 

 shining, not densely clothed with short cinereous hair, which is feebly 

 condensed in the usual thoracic vittae, on the third elvtral interspace 

 and in a broad sublateral vitta occupying intervals 7-9, but without 

 nucleation at any part. Beak rather slender, nearly as long as the 

 prothorax, at least in the 9 , not densely, finely punctate, with numer- 

 ous coarser punctures toward the base ; a deep fovea between the eyes 

 and a linear one between the antennae. First and second funicular 

 joints equal in length, the first a little stouter. Prothorax nearly or 

 quite as long as wide, sides parallel or very faintly convergent and 

 nearly straight to apical fourth or fifth, then rather abruptly con- 

 stricted; median line narrowly impressed, a little more broadly and 

 deeply so behind ; coarsely and rather closely punctate, the interval 

 finely closely punctulate. Elytra not quite two and one-half times as long 

 as wide, but little wider than the prothorax and not quite three times 

 as long, sides parallel in basal three-fifths, thence gradually narrowed, 

 tip acutely not deeply notched ; elytral series not impressed, moder- 

 ately coarse. Thighs feebly annulate; hind tibiae about three-fourths 

 as long as the femora. Length (exclusive of beak), 6.7-10.4 mm.; 

 width, 1.9-3 mm. 



Type. — From Santa Monica, California. 



Found about the roots of plants growing on the sand dunes 

 immediately adjacent to the beach. I have long associated 

 this species with semivittatus Csy. of Arizona and Utah, to 

 which it is closely similar. The difference in habitat would 

 certainly indicate specific distinction, and a closer study con- 

 vinces me that this is the case. The chief differences oberv- 

 able are as follows : There is never any trace of a vitta on 

 the fifth interspace of the elytra in maritimus, the other vittae 

 being at best feebly defined and evident only in well pre- 

 served specimens. The beak is a trifle longer, the prothorax 

 rather more densely punctured and the tibiae relatively a little 

 longer, being about three-fourths as long as the femora, while 

 in semivittatus they are about two-thirds as long. 



L. perloiig'us n. sp. — Very elongate, subcylindrical, black, feebly 

 shining ; pubescence yellowish-gray, sparse and short on the thoracic 

 disk, denser in a di-stinct moderately wide lateral vitta ; evenly nucleated 

 throughout on the elytra, somewhat denser laterally but without well 

 defined vitta. Beak cylindrical, moderately curved, not stout, a little 

 longer than the prothorax, not at all carinate, rather finely and closely
