Beskrivelse af Hunnen. Legemet er (se PI. XI, 
Fig. 1, 2 og 3) noget slankere og mindre underssetsigt 
bygget end lios de ovrige Arter af Slmgten, idet den stprste 
Brede er kjeudeligt mindre end den halve Laengde. For- 
men er aflang oval, noget smalere i det forreste Parti, men 
forovrigt mesten overall af ens Brede. Rygsiden er noget 
hvselvet, isaer i den bagre Del, og Segmenternes Sidedele 
eller Epimerer horizontal udstaaende. Som hos de o'vrige 
til denne Familie horende Former kan man paa Legemet 
adskille et forreste og et bagerste Parti, hvoraf hint sam- 
mensaittes af Hovedet og de 4 forreste Forkropssegmenter, 
dette af de 3 bagerste Forkropssegmenter og Bagkroppen.

Specific Character. — Body oblong in fonn, with 
length more than twice exceeding breadth, and but slightly 
dilated in the middle. Anterior section of body (head 
and the 4 anterior segments) considerably shorter than 
posterior, and separated by an appreciable instriction. 
Head without any distinct frontal projection, but with the 
oral region prominently protruding. First segment scarcely 
at all broader than head; the 3 succeeding segments with 
uniformly rounded epiinera. The 3 posterior segments all 
well defined, and uniform in size. Abdominal segment 
exceedingly large and broad, posteriorly somewhat pro- 
duced in the middle. Second pair of antennae about 4 
times as long as body, with the 2 outer joints of peduncle 
greatly produced, and the flagellum but very little longer 
than the former. Mandibles without teeth, cutting edge 
smooth. First pair of legs with last articulation unusually 
short and terminal claw rudimentary; the 2 succeeding 
pairs almost twice as long as body. Natatory legs with 
the 2 outer foliaceous articulations well-nigh uniform in 
size; terminal claw exceedingly small. Caudal appendages 
very diminutive, with outer branch considerably smaller than 
inner. Colour a uniform light-yellow. Length reaching 
Locality. — Stats. 33, 124, 251, 286, 312, 362,363, 
Description of the Female. — The body (see PI. 
XI, figs. 1, 2, and 3) is somewhat more slender and less 
thickset than in the other species of the genus, its greatest 
breadth being appreciably less than half the length. The 
form is oblongo-oval , a trifle slimmer throughout the 
foremost part, but elsewhere exhibiting an almost uniform 
breadth. The dorsal face is somewhat arcuate, more es- 
pecially the posterior portion, and the lateral parts of the 
segments, or the epimera, project horizontally. The body, 
as in the other forms belonging to this family, has an an- 
terior and a posterior section, the former consisting of the 
head and the 4 first segments, the latter of the 3 posterior
