JAMES WATERSTON. 



each side of the clypeus up to the genal keel 9-11 bristles, 3 being before the keel, 

 5-6 along each orbit up to the level of the toruli. The eyes bear scattered very 

 minute bristles. Vertex and upper frons very strongly raised reticulate so as to 

 appear rough-pitted ; lateral ocelli just over one-half their diameter from the 

 orbits. 



Blouth-jmrfs. Labrum narrow, two-fifths the width of the clypeal edge, with 

 a rather stout bristle at each lateral angle and two clear pustules medianly above 

 the edge. Mandibles (fig. 5 b, c). Maxillary palpus, 10 : 7 : 9 : 17 (measured along 

 the outside edge) ; first joint triangular, constricted basally, bare, as also is the 

 second; the third with two bristles; fourth joint (as wide as the length of the 

 second) with about a dozen bristles evenly distributed and 3 much longer (hyaline) 

 at or near the apex. The galea bears 8-9 shorter superficial bristles and 6-7 more 

 spine-like ones on or near the edge. Labial palpus, 8:2:7; the second joint hardly 

 discernible on the imier edge. 



Antennae (fig. 5, a). Length '55 mm., bulla (6 : 5) two-fifths of the scape, which 

 is, as in H. dalmani, Westw. (Philos. Mag., x, 1837, p. 440), nearly twice as long 

 as broad. Pedicel about as long as the scape is broad, hardly longer than broad 

 (17 : 15) and shorter (17 : 20) than, but as broad as, the first normal funicular

joint, which in turn is shorter than the second (20 : 23) ; ring joint minute. The 

 two funicular joints (as long as bulla and scape together) are, with the club, in the 

 ratio 5 : 6 : 35. Taking the width of the funicle as 3, that of the club at its maximum 

 is about 4. The sensoria of the funicle and club are long and numerous ; the bristles 

 are sparsely set (fig. 5, a). 



Thorax just longer (9 : 8) and ^\^der (10 : 9) than the abdomen, which is as broad 

 as the head. Pronotum with the spiracular emargination small, shallow and 

 indistinct, with 1 strong and 1 weaker bristle above the posterior row (6, 6), and
