The following is a detailed description of the female type, 

 contained in the Hopeian Collection : — 



Body long and cylindrical, brownish green, rather shining ; 

 meso- and metathorax and basal segments of the abdomen 

 finely granulated, especially the former. Head oblong, 

 simple. Antennae very long and slender, with very long 

 joints ; the hind margin of the metathorax and of the two 

 basal segments of the abdomen with a small raised tubercle 

 in the middle, the fifth segment with a larger tubercle in 

 the same situation, the eighth with the middle of its hind 

 margin raised into an obtuse conical point ; the operculum 

 extending far beyond the extremity of the abdomen. The 

 fore legs are moderately long and simple ; the middle and 

 posterior are shorter and stronger ; their femora with two 

 foliated lobes near the base on the under side, and two 

 similar ones on the upper side near the tips. The four 

 posterior tibiae have the apex triangularly dilated. The 

 Berlin specimen of the female has the upper surface of the 

 body rather more strongly granulated, and the five basal 

 segments of the abdomen have the raised tubercle in the 

 middle of the hind margin. The following are the dimen- 

 sions of the Hopeian specimen of the female : — 



Long. corp. fcem. cum operc. unc. 5g ; cap. tin. 3^ ; 

 anten. unc. 2| ; proth. lin. 3; mesoth. lin. 13y; metath. 

 lin. 9£ ; abdom. lin. 22+ lin. 6 + operc. ultra apicem ab- 

 dom. extenso, lin. 8=lin. 36. 



Note. — I think it not improbable that the typical spe- 

 cimen of Bacteria foliacea of Blanchard {ante, p. 26, 

 sp. 17 (70)) may prove to be a young individual of B. 

 phyUopoda.

Bacteria spatulata, Blanchard in Gay's Hist. Chili, vi. 25, 

 Orth. pi. 1 . f. 6 (nee Burmeister). 



The unique specimen in the Jardin des Plantes is muti- 

 lated at the extremity of the body, so that its sex is not 

 easily determined. I, however, believe it to be a female, 

 from its general agreement in the proportions of its parts 

 with that sex of B. phyUopoda.

The following are the dimensions of the typical specimen 

 of the male of this species contained in the Royal Museum 

 of Berlin (the female described by Burmeister, from the 

 same Museum,'being evidently immature) : — 



Long. corp. maris, unc. 2| ; cap. lin. 11 ; anten. unc. 2£ ;

This sex is extremely slender ; the prothorax is finely- 

 granulated ; the legs very long and slender ; the terminal 

 ventral segments of the abdomen produced very much be- 

 neath, but not extending beyond the middle of the eighth 

 dorsal segment ; and the anal styles are long, extending 

 considerably beyond the extremity of the body, curved,
