THREE NEW SPECIES OF CEBRIO (COLEOP., 
CEBRIONID^E) 1

While rearranging the Cebrionidae in the Museum of Com- 
parative Zoology, recently, I noted three distinct new species. 
They are described in this paper. 
Cebrio abnormis sp. n. 
Male. Slender, tapering behind. Head, pronotum, and scutel- 
lum dark brown. Elytra pale, almost white (specimen collected 
in alcohol), with the apices light tan one-third the length of the 
elytra and with a tannish suffusion extending forward along the 
suture, becoming broader on the basal third. Antennae and 
mouth parts pale tan. Below brown, with tips of abdominal 
sternites, tibiae and tarsi paler. 
Head moderately densely and deeply punctured. With a pair 
of protuberances just in front of and inside the bases of the 
antennae, connected by a vague, posteriorly directed U-shaped 
ridge. Front concave, with the median portion irregularly im- 
pressed. Labrum with the sides oblique and with a shallow 
U-shaped excavation at the apex. Mandibles moderate in size, 
a little more slender than in bicolor. Last segment of the maxil- 
lary palpi as long as the third, expanded apically and almost 
squarely truncated. Antennae strongly serrate, from the third 
segment. First segment darker than the rest. Third segment 
almost twice as long as the second and three-fourths as long as 
the fourth (excluding the process of the fourth). The fourth 
segment has the largest process of any of the segments. The 
distance from the tip of the process to the other side of the 
antennae is as great as the length of the segment, excluding the 
process. The processes on all the segments are more slender
