HyYLoBIUS PACKARDII. 
J2loxe, (Dively 418}. 
A second species of the genus has been found at the same locality as the 
last. The head is poorly preserved, but the eye ismuch smaller than in H. 
provectus, though still large and transversely oval; the rostrum is faintly 
arcuate, slender and nearly equal or slightly enlarged in the apical half, and 
nearly as long as the head and thorax together, not very broadly rounded at 
the tip. Thorax very short for an Hylobius, much broader than long, witha 
median longitudinal impression, and the surface finely, distantly, and rather 
faintly punctate. Elytra considerably more than twice as long as broad, - 
equal on the basal two-thirds, the striz fine and slight with small delicate 
distant circular punctures. Legs rather long, femora rather slender. 
Length, excluding rostrum, 6-4"; rostrum, 1:25™"; elytra, 4:9"; 
height of body, 2 75™".

Hy Lopius LACOEI. 
Pl x; Pies 15. 
Head nearly three times as high as long, finely punctate. Eye pretty 
large, transverse; rostrum stout, nearly as long as the pronotum, its upper 
edge arcuate, the lower straight, the tip well rounded; antennze inserted 
near the middle of the rostrum, the scrobes nearly straight and slightly 
declivent, running toward the eye, enlarging to the tip, the funicle and scape 
of about equal length ; thorax fully half as high again as long, truncate at 
each extremity, tapering somewhat with arched dorsum, the surface densely
