fourth three times a=; long as broad. The fourth joint is prolonged 

 distally on the posterior or inner side into a slender conical process. 

 The fifth joint is slightly shorter than the fourth, broadest a l*^tle 

 beyond the middle, bluntly pointed distally. A pair of pigmented 

 ocelli is present immediately behind the antennae. 



The mandibles appear broad from in front, but very narrow 

 from the side. They are convex in front and concave behind and 

 are strongly arched distally. There are three terminal teeth on 

 the left side and two on the right, the most ventrally situated being 

 apical in each case. The left molar tooth is a large hollowed 

 cusp with two transverse ridges, the distal of these uniting with the 

 anterior margin to form a distinct denticle and the proximal unit- 

 ing to form a large spine. The anterior margin of the cusp is very 

 strongly elevated. The right molar tooth consists of two distinct 

 cusps, of which the distal is triangular with the angles raised into 

 small denticles and the proximal is broadly L-shaped, its most 

 proximal portion being very strongly produced in the same plane 

 as the mandible. 



The lobe of the maxilla bears a stout and somewhat conical 

 terminal spine with two similar but smaller spines, united at the 

 base, in a line with it on the inner side. The inner margin bears a 

 row of strong spines, followed on the dorsal surface by others 

 which become weaker and disappear towards the base on the outer 

 side. The ventral surface bears two rows of spines distally between 

 the rows on the inner and outer margins, the distal spine alone being 

 specially stout in the outer row, and the distal and penultimate in 

 the inner row. The stridulatory spines are /^/-shaped. The maxil- 

 lary palps are mounted on a broad protuberance and are four- 

 jointed. The first joint is short and broad, more or less transverse. 

 The second is narrower, and perhaps a little more than twice as 

 long as broad. The third resembles the second but is perhaps a 

 little shorter. The fourth is about as long as the second but 

 tapers slightly at both ends. 



The labial palps are two jointed, each joint being about 

 twice as long as broad. The labium is set with long spines in front 

 of the palps and bears a pair of very long hairs between them. 

 There is a pair of similar hairs on the membrane between the 

 labium and the mentum. There is a spine on each side of the 

 mentum near the posterior margin. 



The legs bear long and slender spines below, which tend to 

 be more or less filamentous on the proximal joints but stronger on 

 the distal ones. There area few long hairs, not very definitely 

 arranged, between the anterior legs; there is also a line of them 

 between the legs on each of the two remaining thoracic segments 

 and across the lower surface of each of first nine abdominal seg- 

 ments, becoming sparser behind. 



The thoracic segments are each divided into three transverse 

 ridges above, and each of these ridges bears a line of long hairs. 



The first abdominal segment is undivided above, and bears 

 a line of similar hairs mixed with slender spines of a darker colour.
