 501. Lixus leptosomus Blatch. 



Two specimens were taken April 11 while sweeping low herbage 

 along a railway embankment near Dunedin, Fla. The unique type, 

 the only specimen hitherto known, was from Sanford, that State. 



Lixus bischoffi Fall, Bull. Brook. Ent. Soc, XVI, 1921, 40. 



A species allied to concavits Say but with elytra distinctly wider 

 than thorax; antennal club shorter and stouter, scarcely longer than 

 half the funicle; length of body 13 mm. Five specimens were taken 

 by Bischoff early in September from a large flowering thistle near 

 Berkeley Heights, N. J. 



Lixus cavicollis new species. 



Elongate, subcylindrical. Black, thinly clothed above with very short, 

 fine, ash-gray hairs, these condensed to form a vague pale stripe along sides 

 of thorax and elytra ; beneath more thickly clothed with longer similar 

 hairs ; antennae reddish-brown, tarsi piceous. Beak stout, a little shorter 

 than head and thorax, feebly curved, densely reticulate-punctate and with a 

 shallow elongate fovea between the antennal pits at apical third. Antennas 

 stout, scape not reaching eye, first joint of funicle two thirds the length 

 of second, the latter one half longer than third and fourth united. Thorax 

 subcampanulate, one fifth wider at base than long, sides almost straight, 

 gradually converging from base to apex; disk with widely scattered coarse
