A NEW GENUS AND SPECIES OF BLENNOCAMPIN^ 



FROM TEXAS. 



BY ALEX D. MACGILLIVRAY, ITHACA, N. Y. 



Hie following species was received from Dr. L. 0. Howard, of the U. 

 S. Department of Agriculture, for identification. It was found after 

 careful study to represent an undescribed genus. This genus would fall 

 in the tables next to P/iymatocera^ Dahlb., from which it is readily 

 separated by having the antennae strongly serrate on one side, ihe posterior 

 metatarsus as long as all the following segments together, and the posterior 

 ,. tarsi shorter than the posterior tib'ae. 



Ceratulus, n. gen. — Antennae with nine segments, all the segments 

 except the first, second and ninth strongly ])roductd on one side at apex, 

 the first segment large and globular, the second segment small, broader 

 than long, the third segment short, about twice as long as broad at apex, 

 the fourth segment twice as long as the third, the fifth shorter than the 

 fourth and longer than the third ; malar space narrow, hardly more than a 

 line ; legs with ihe front and middle tarsi longer than the tibiae, the 

 posterior tarsi shorter than the libi?e ; the posterior metatarsus as long 

 as all the following segments together; the claws cleft; the front wings 

 with the radial and the radio-medial cross-veins i:)resent, ihe medio-cubital 

 cross-vein parallel with the free part of Mg + 1, the anal cell peliolate, the 

 radii) 1 cross- vein and the free part of R^ inclined at the same angle, and the 

 free part of M^ + Cuj slightly nearer the medio-cubital cross-vein than the 

 free part of M3 + 1; the hind wings with the free part of M2 present, the 

 first anal cell slightly petiolate at apex. Type Ceratulus spectabilis^ 

 MacG. 



Ceratulus spedahilis^ n. sp. — ' ^ and 9 • Body rufous or reddish, 

 with the antennae, the tips of the mandibles, the sutures around the 

 ocelli, the legs beyond the apical fifth of the femora, and the saw-guides, 

 black ; the wings strongly infuscated, the veins and the stigma black ; tlie 

 labrum broadly rounded, the clypeus truncate ; the antennal furrows 

 extending to a large circular excavation above the bases of the antennae, 

 interrupted on the middle of the front, and continued from opposite the 

 lateral ocelli as narrow, line-like furrows to the occiput ; the antennal 

 fovea broad, bounded below by a distinct ridge, the lateral walls of the 

 fovea continued to the ocelli, where ihey form prominent ridges between 

 the median and lateral ocelli, the lateral ocelli being placed on the sides 

 of the ridges and therefore facing out ; the postocular area not bounded in
