with a conical process at the extremity of the femur. Length of the proboscis, 4 mm. ; of the 

 cephalic segment and trunk, 5 mm.; of the abdomen, 1 mm.; of a false leg, 6 mm.; of an 

 ambulatory leg of the second pair 12,5 mm. 



This species differs from all the known species of the genus in the narrow shape of the 

 proboscis^ which, after swelling out from its base, narrows for the distal half of its extent".

„The body of this species is rather long and slender, the „neck" or portion intervening 

 between the point of insertion of the second pair of appendages and that of the third, about 

 half the length of the rest (exclusive of the abdomen). The intersegmental lines are very distinct. 

 The lateral processes are not in contact with one another, but not very wide apart, those of 

 the third pair of appendages being more widely separated from the fourth than any of the 

 following pairs are from one another. The proboscis is very large, as long as the neck and 

 first segment, long oval, with the ends somewhat pointed. The abdomen is narrow cylindrical, 

 notched at the extremity, equal in length to the last two segments. The first pair of appendages 

 are very small, scarcely one-third of the length of the proboscis; the first Joint is narrow, 

 slightly incurved, rather broader distally than proximally; the second is ovate, about one-fourth 

 of the length of the first. The second pair of appendages are about four and a half times the 

 length of the first, and are longer than the proboscis; the first Joint is short and thick; the 

 rest slender, the second very much the longest, thicker at the distal than at the proximal end; 

 the third about a quarter of the length of the second, the fourth two-thirds of the length of 

 the second, the fifth very short ; the sixth nearly half of the length of the fourth ; the seventh 

 equal in length to the sixth ; the eighth a little shorter, and the ninth shorter still ; the ninth 

 Joint is ornamented with a few short hairs. The basal Joint of the third pair of appendages is 

 small; the second twice as large as the first, curved; the third rather smaller than the second; 

 the fourth twice as long as the third; the fifth rather shorter than the fourth and more slender 

 towards the proximal end ; the sixth nearly two-thirds of the length of the fifth ; the seventh 

 about equal to the sixth; the eighth rather smaller; the ninth and tenth nearly equal in length; 

 the last four segments are ornamented with pinnate hairs ; the last terminates in a curved claw. 

 The fourth, fifth, sixth and seventh pairs of appendages have each short basal joints, each of 

 which has two short lateral processes near its distal end; the second Joint is a little longer 

 than the first, the third equal to the first: the fourth is longer than the three first together; 

 the fifth is somewhat longer than the fourth; the sixth about the same length as the fourth, 

 but more slender; the seventh about half the length of the sixth; the eighth, the Joint between 

 which and the seventh is scarcely discernable, is equal in length to the seventh ; the claw is 

 longer than the eighth segment, tapering distally, and resembles an additional segment".
