which is rather deepl}' concave with a median process rather more

Length : 12 mm. in one specimen, average about 8 mm. 



E. pocillimamis is apparentl}' very common ; it was represented 

 in the collection by upwards of 30 specimens, some of which were

First antennae more than half as long as body with peduncle 

 about as long as flagellum ; second joint of peduncle slightl}' longer 

 than first but more slender ; third joint ver}' short and scarcely to 

 be distinguished from first segments of flagellum, which is composed 

 of about 17 segments gradually diminishing in length toward apex; 

 accessory flagellum of moderate size made up of 6 joints. Second 

 antennae shorter than first, gland cone ver}- slender and long, 

 reaching nearly to apex of third segment, which is stout, about 

 twice as long as broad ; fourth and fifth segments long and slender, 

 fifth slightly longer than fourth ; whole peduncle longer than that of 

 first antennae; flagellum not as long as last 2 joints of peduncle, 

 made up of about 8 gradually diminishing segments. 



Mandibles with all parts well developed ; palp 3-jointed with first 

 of moderate size, broader apically and produced on inner margin 

 to form triangular process distally, third joint about ^j^ as long as 

 second, provided apically with several very long setae; principal 

 cutting edge denticulated, secondary cutting edge made up of about 

 6 slender teeth ; 6 spines in spine row ; molar tubercle rather large. 



First maxillae with 2-jointed palp, of which the proximal one is 

 slightly longer than broad and the distal one is more than twice 

 as long as broad with a blunt apex bearing numerous setae ; outer 

 plate rather long and slender and somewhat curved with numerous 

 branched and forked spines on distal margin ; inner plate triangular 

 with fine pinnate spines on inner margin and apex. Second maxillae 

 wdth plates of nearly equal size, inner one slightly broader than 

 outer which is the longer of the 2, plates rounded apically and 

 provided with setae. Maxillipeds with 4-jointed palp, first joint short, 

 second moderately long, extending l^eyond apex of outer plate, with 

 setae on inner margin ; third joint al^out twice as long as wide and
