REPORT UPON A COLLECTION OF 



smaller and straighter than the larger of the marginal spines. Anal ring 

 with eight setae, these about half as long as the anal lobe setae. Legs with 

 the tarsus slightly longer than the tibia, the claw with a distinct tooth, the 

 posterior coxae with numerous small pores beneath. Antennae (Fig. 4A) 

 6-segmented, the third segment as long as or even slightly longer than the 

 last three together. Wax ducts (Fig. 3D) with a rather broad, deep and 

 symmetrical cup. 



Notes: Examples from this material have been compared by Mr. Morri- 

 son with specimens in the National Collection at Washington and this determina- 

 tion has been confirmed by him. The species was originally described as a variety 

 of E. tinsleyi, but the latter species is quite different, having the dorsum thickly 

 beset with stout spines.

Morphological characteristics. Adult female (on slide) 3 mm. long. 

 Derm entirely destitute of spines and setae except for the usual slender 

 setae on the venter of the abdomen, a very few extremely small spines 

 on the dorsum and a slender spine (Fig. 5B) at the lateral margin of 

 the last two or three abdominal segments. Anal lobes (Fig. 5C) promi- 

 nent and quite heavily chitinized, each with two quite long and slender 

 setae on the dorsum and two somewhat longer setae on the ventral side. 

 Antennae (Fig. 5A) 6-segmented, the third segment longer than any 

 three others together. Legs with the tarsus slightly longer than the tibia, 

 the claw with a denticle, the hind coxae with numerous pores beneath. 

 Wax ducts (Fig. 5D) of two sizes, some quite small and with the cup
