381 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



is moderately arched above, the profile-line sloping forwards, with 

 a slight general curve from the thoracic junction to the eyes ; the 

 normal grooves and indentations are fairly marked, and of a slightly 

 dusky hue. 



The eyes are large, rather closely grouped, and in two nearly 

 parallel slightly curved lines of equal length, the curve directed out- 

 wards ; and the height of the clypeus is considerably less than half 

 that of the facial space. The four eyes of the hinder row are equally 

 separated from each other, the intervals, however, being very small ; 

 the eyes of the hind central pair are larger than the hind laterals, 

 oval, and a little obliquely placed ; they are pearly, of a grey hue, 

 the laterals of both rows being pearly also but white, the fore centrals 

 dark ; these last are the smallest of the eight, and the interval between 

 them is greater than that between each and the fore lateral on its 

 side, the fore laterals being very nearly contiguous to the fore 

 centrals, oval, oblique, and apparently the largest of the eight, though 

 not much larger than the hind centrals, and each is separated from 

 the hind lateral on its side by an interval about equal to the diameter 

 of the latter. The length of the curved oblong figure formed by all 

 the eyes is, as nearly as possible, double that of its width. 



The legs are moderately strong, rather long, their relative length 

 being 4, 1, 2, 3 ; they are furnished sparingly with hairs and slender 

 bristles, with a few spines on the tibiae and metatarsi of the two 

 hinder pairs ; each tarsus ends with two curved claws, pectinated at 

 their base ; the claws on the tarsi of the fourth pair of legs are 

 longer and rather stronger than the rest. 



The palpi are rather short and not very strong ; they are furnished 

 with hairs and bristles, a rather conspicuous tapering black bristle 

 issuing from the fore extremity on the upperside of the cubital joint ; 

 this joint and the radial are of equal length ; the latter is rather less 

 strong than the former, and has its fore extremity on the outer side 

 produced into a small, tapering, bluntish-pointed apophysis, not 

 much exceeding in length one third that of the joint itself. The 

 digital joint is not very large ; it is of ordinary form ; and its length 

 is considerably less than the united lengths of the radial and cubital 

 joints. The palpal organs are simple but well developed, consisting of 

 a large, oval, corneous lobe, broken up at its fore part into one or two 

 irregular corneous processes. 



The falces are strong, moderately long, a little projecting forward, 

 arched, but not very prominent near their base in front, where they 

 are furnished with some prominent bristles. 



The maxilla are strong, moderately long, inclined as well as curved 

 towards the labium, and strongly impressed across the middle of the 

 front surface ; the point of issue of the palpi is slightly above the 

 middle point between the base and extremity ; at this point the 

 maxillae are very broad and strong : in these and other respects 

 there is no difference from the generic type. 



The labium is two thirds of the length of the maxillae, of an 

 oblong form, rounded a little on the sides as well as at the apex. 



The sternum is of ordinary form ; it is glossy and has its margins
