280 NATURAL History BULLETIN. 
posterior margin is slightly produced, not emarginate laterally, 
semicircularly emarginate at middle between the oblique 
ridges; in the middle of this segment is a U-shaped elevation. 
The second segment is very long and narrowly produced, 
depressed along the base, with the usual large, punctured, 
median fovea. The sides of the prolongation are broadly 
emarginate and obliquely narrowly depressed on the surface, 
the middle of the segment from the basal fovea to the tip very 
high, elevated, flat above and as broad as one-fourth of the 
base of the segment, overreaching the last segments perpen- 
dicularly. Jegs and antenne presenting no peculiarities. 
Habitat. Atlantic States. 
B. uLKE!, Brendel. Brownish-black, punctulate, pubescence 
short, elytra, legs and antenne red, palpi yellow. Length, 
1.8mm. Plate VIII., Fig. 54. 
Head, excluding the eyes, wider at base than the frontal 
margin, occipital foveze open toward the eye, a faint line con- 
necting them with the frontal tubercles. Awfenne slender, 
half as long as the entire body, first joint very strong, second 
half as thick, obconical, twice as long as _ wide, third to eighth 
subequal, eighth quadrate; ninth and tenth obconical, together 
as long as the three preceding; eleventh oblong, equal in 
length to the ninth and tenth together. Prothorax as long as 
broad, widest through the middle, polished; base at the sides 
behind the lateral fovez slightly transversely impressed. 
Abdomen punctured, margins of the first segment slightly 
-divergent, carinz visible, less than one-third of the segmental 
width apart. /ytra one-half longer than the prothorax, 
width at the shoulders the same, at the tip one-fourth broader ; 
disk punctulate, sides very slightly arcuate, the discal and 
sutural lines parallel, deeply impressed, originating in deep 
basal punctures. ¢ abdominal basal segment produced from 
the lateral margin to the middle, the outlines oblique, converg- 
ing, the middle semicircularly emarginate, leaving on each 
side of the emargination a long spinous process. Disk from 
the basal angles broadly, and towards the spines narrowly
