the sub-apical row extending from the antennal groove to the 

 vertex, is oblique, and is composed of six, of which the first four 

 are of equal length oi- nearly so, and the other two distinctly 

 smaller, the sixth being shorter than the fifth ; in the second row 

 there are five bristles, of which the first two are very long, the 

 third somewhat shorter, and the fourth and fifth much smaller 

 still ; the third row fringes the basal angle of the head, and 

 consists of five ; the bristle nearest the antennal groove is not 

 only the longest of the series, but is widely separated from its 

 nearest neighbour ; of the others constituting the third or posterior 

 row, the three median bristles are of equal length, or nearly so, 

 and the fifth is much the smallest ; below the antennal groove, 

 and immediately before the first of the basal row of bristles, 

 there is an irregular group of short, stiff hairs or bristles, and 

 again betw^een the first and second bristles, a row of three short, 

 fine hairs. In front of the antennal groove 

 there are two long bristles placed one beneath 

 the other, though somewhat widely apart. The 

 first row of six fine bristles in front of the 

 head is divided into two series of three each by 

 the interception of two short but exceedingly 

 robust horn-like bristles, of which the anterior 

 one is not only much the longest, but gently 

 curved (fig. 3). The second segment of the 

 maxillarly pulpus is longer than the fourth, and 

 the rostrum reaches beyond the end of the fore 

 Tj,. .._ coxa. Apical extremities of the first and second 



Ceratophiillus .joints of the antennfe are fringed with a row of 

 rothscMldi. short stiff black hairs or bristles. 



Thorax. — The pro-notum has a comb of about 18 teeth, and 

 two rows of bristles, those of the posterior row being much the 

 longest, widely separated from each other individually, and over- 

 lapping the comb ; there are also a number of short fine hairs 

 scattered over the surface. The meso-notum has three recurved 

 I'ows of bristles and a few fine, scattered hairs ; the bristles con- 

 stituting the posterior row ai-e much the longest, and those of the 

 anterior row much the shortest ; the meso-thoracical epimerum 

 has two vertical though somewhat oblique rows of two bristles 

 each, and beyond these one single bristle, all of which are very 

 long ; besides these there are a few shorter ones present. The 

 meta-notum is also provided with a few scattered fine hairs, and 

 three rows of bristles similar to those on the mesa-notum ; the 

 meta-thoracical epimerum has two pairs of long and a few short, 

 tine bristles.. : -
