468 MR. R. I. rococK on the 



20. Nbwportia pusilla, sp. n. 



Colour : head and first tergite and anal tergite ochraceous ; 

 body dark green mottled with ochraceous ; legs pale green ; 

 antennae yellow. 



Head hairy, punctured, not sulcate. Antennae composed of 

 seventeen short segments, shortly and thickly hairy. Maxilli- 

 pedes hairy, anterior border of the coxse straight with a median 

 notch. First tergite with a strong arched groove running from 

 the anterior angle on one side to that of the other, and reaching 

 nearly to the middle of the plate ; the longitudinal sulci invisible. 



Terga and sterna normally sulcate. 



Anal somite also normal, the pleurae somewhat scantily porous. 

 Ziegs hairy, with femur and patella about equal in length, the 

 tibia a little shorter ; the tarso-metatarsus composed of ten dis- 

 tinctly defined segments, of which the first is rather more than 

 half the length of the tibia, the second being a little shorter and 

 thinner than the first, as the third is with regard to the second ; 

 the seven distal segments shorter, the seventh ovate. 



Length 10*5 mm. 



Locality. St. Vincent {H. H. Smith). 



This species, with its distinctly segmented anal tarsi and the 

 large spines on the lower surface of the anal femur, falls into 

 the same category with the three mentioned above. It may be 

 recognized from them, however, by the presence of only three 

 spines on the femur, and none on the patella of the anal leg. 



21. Newportia Ernstti, Pocock, Ann. Mag. Nat. Hist. (6) 

 viii. pp. 161-163. 



Locality. St. Vincent {H. IL. Smith). 



This species was originally described from a specimen received 

 from Caraccas from Dr. Ernst ; the Museum also has an example 

 from Brazil. Consequently there is very little doubt that the 

 species has been introduced into St. Vincent from the mainland 

 of S. America. 



It cannot be confounded with either of the preceding on 

 account of the indistinctness and number of the segments of its 

 anal tarsi, the spine armature of the anal legs, sulcation of head- 

 plate and first tergite, &c.
