Ceratophyllus utahensis sp. nov. 
Head.—The frontal notch is high up. There are two rows of 
three bristles each on the frons, the lower row running from 
above the eye to the base of the maxilla, the upper from a point 
midway between the eye and the top of the head and the base 
of the maxillary palp. There are three minute bristles above 
the eye and two more, slightly larger, on the anterior margin of 
the antennal groove near the base of the antenna. The entire 
head is sparsely but regularly punctured; however, there are 
no visbile hairs arising from these punctures. The eye is very 
large, overlaps the antennal groove near the upper part and nearly 
touches the genal margin. Its diameter (vertical) is equal to the 
length of the third segment of the maxillary palp. The gena 
behind the eye is sharply pointed. The first segment of the an- 
tenna bears numerous small hairs and the hairs arising from the 
second segment reach the tip of the antenna. On the ‘occiput 
there are three stout bristles, one appearing as a continuation of 
the upper row on the frons and two as a continuation of the 
lower row. There is one large bristle at the lower posterior 
angle of the occiput.and a subbasal row of about ten across the 
dorsal part. 
Thorax.—The pronotum carries a ctenidium of about 26 
spines on the posterior margin, and a row of about 12 bristles 
anterior to this. On the mesonotum there is a submarginal row 
of 10 bristles and two rows of much smaller bristles before this ; 
on the metanotum the submarginal row is of nine bristles and 
there are three rows of smaller bristles. On the mesosternum 
there are two bristles, on the mesopleure, five. On the meta- 
sterum there is one bristle near the upper posterior corner, the 
metepisternum bears two and the metepimeron five. 
Abdomen.—tTergites I-IV bear near the dorsal line on each 
side two short heavy teeth. In addition, there are two rows of 
bristles on each tergite; the numbers for one side only are as 
follows:
