tex; this part is connected insensibly by a furrow with the prominent globe and 

 also facetted, therefore the eyes are in fact very large, though probably only the 

 small globe serves for vision in the nympha stage, as its facets are very much lar- 

 ger; the part behind the eyes is separated by a sharp, defined, curvate line, rough 

 by fine tubercles: on each side a rounded flat spot, a smaller one in the middle, 

 and a large ill defined one each side on the hind angle; all those spots are entered 

 from behind by some irregular lines formed by fine tubercles; vertex round, small, 

 convex, with ocelli, the lateral ones more defined; front border of head between 

 antennse forming a semi-circular plate, strongly prominent, when seen from below, 

 with a comb of long, flat spines; antennae as long as head, 7-jointed, tapering, 

 slender; the two basal joints short, thicker, second a little longer; the other joints 

 form a tapering, slender seta; third joint as long as fourth to sixth ; the last four 

 joints of equal length, seventh pointed; nasus transversal, strongly surpassed 

 above by the front lobe, forming with it a deep groove, to which the palpus of the 

 mask reaches; labrum short, very broad, deeply notched on front margin, sides 

 rounded ; mask longer, extending a little beyond middle legs, triangular, very 

 little longer than broad ; sides bent up, sloping to base, which is about one-fourth 

 as broad as the front part; the middle third produced in a large triangular lobe, 

 hollowed beneath at base, with two strong teeth on tip and a comb of short scales 

 on each side : palpus large, triangular, very much enlarged at inner border, deeply 

 denticulate, the denticulations of the opposite palpi closely fitting into one another; 

 movable hook short, sharp, slender; prothorax less than half the length of head, 

 and two-thirds of its breadth with a small lobe in middle; front part a trans- 

 versal lobe; hind part raised, bisinuated ; stigmata large, narrowed ; wing cases 

 reaching 5th segment; abdomen as broad as head, long, three-fifths of body, cy- 

 lindrical above, flattened beneath, broad one-third of its length; segments of 

 nearly equal length, 8th to 10th shorter, tapering to tip ; apical margin of seg- 

 ments with long hairs; lateral spines on 9th very short, but every where among 

 the long hairs are intermixed heavy spines ; inferior anal appendages twice as 

 long as 10th segment, pyramidal, very sharp; the middle one a little shorter; all 

 with apical half bent down a little; lateral ones very short, half the length of 

 segment 10, very sharp; abdomen below covered with fine, short, hairs; longi- 

 tudinal sutures straight, ending on 8th segment, space between them four times 

 broader than lateral space; female genitals representing two approximated conical 

 lobes reaching 10th segment; legs very hairy, flattened, strong, formed for run- 

 ning; at base widely and equally separated; tibise about as long as femora; tarsi 

 .3-jointed; hind legs reaching 8th segment; claws sharp; numerous spines on the 

 under side of legs. 



A younger male from Kooloo 27 mm. long is similar ; on each seg- 

 ment near the middle of dorsum a black eye-spot on each side, repre- 

 sented by darker spots on the female ; male genitals indicated by the 

 usual impressions on segments 2, 3 and 9. 



The nympha raised by Dr. Brauer has the superior middle appendage 

 one-half the length of the inferiors (laterals by Cabot p. 14, is an error 

 for inferiors) and blunt. 



The second female raised by Prof. Zeller has the superior middle ap- 

 pendage similar to the other specimens, so that Dr. Brauer's specimen
