mixed with longer filaments, the third 

 distal part of which is widened and 

 ramose ; femora, except the anterior tibiae 

 and metatarsi, with three longitudinal 

 rows of spatiilate, striate and almost de- 

 pressed scales. Tarsal and hooks of the 

 9 simple ; (? unknown 



Abdomen depressed, hefcd without longitu- 

 dinal carinae ; palpal joint not obliquely 

 truncate, not at angle with 2 ; antennae 

 ( c? ? ) 7-jointed, joint 2 long, 3-5 trans- 

 verse ; tarsal joints without filaments, 

 ramose, 2 cylindrical, 3-4 sometimes 

 weakly cordiform at end ; legs withoiit 

 scales, 3. 



Tarsal claws of $ bifid, the two ranii equal 

 in length, the medial pointed, the lateral 

 obtuse with the apex widened and finely 

 pectinate. Claws of the 9 simple ; in $ 

 and 9 is visible at the base of the claws 

 a hyaline, glabrous lamina longer and 

 wider than the claw, narrowed at base 

 and then widened, triangular and sharp.

Tarsal claws simple, $ ? , or simple in the 

 9 and bifid and unequal in the $ ; in the 

 first case the medial ramus is very short, 

 and in both the lateral ramus is widened 

 and pectinate at apex, without hyaline 

 triangular lamina. Hawai

Ill the genus Telmatogeton, Schin., founded on T. sancti-Pauli, Scliin., 

 the antennae are 7-jointed (^ $ ), joint '2 obconical, 8-5 transverse, 

 but there is no mention of the 5th tarsal joint being trilobate; besides, 

 the palpi are 4-jointed, the forehead grooved, the alar neuratiou 

 differs from that of Chironomus, the tarsal claws are simple, the 

 pulvilli small but very distinct, the empodium large, filling the whole 

 interval between the claws, and is ciliate in front. 



The insect described by Coquillet under the name of Telmatoyeton 

 tiltiskensis differs from all those mentioned above by the antennal 

 joints 2-6 sub-cylindrical, the 7th only a little longer than the others. 

 It is not said that the 5th joint is trilobate ; the pulvilli and the 

 empodium must be as in Telmatogeton. Claws of $ bifid, of the $ 

 unknown.
