NOTES ON JAMAICAN RHYNCHOTA. 



73 



greatly depressed beneath on its apical half (except at the lateral mar- 

 gins), apical margin slightly excavated ; first three segments longi- 

 tudinally carinate ; connexivum semivertical. Mcicropterom form : 

 pronotum produced basally into a short acute porrect spine ; elytral 

 neuration distinct. 



$ , Third antennal segment and anterior tibire not so strongly 

 dilated as in the male, but more so than in the other species of the 

 genus. Posterior femora incrassate (similarly to the same sex of 

 R. distinct a), armed beneath with one large and two or three small 

 teeth. Sixth (? seventh) abdominal segment very long, nearly twice 

 as long as the fifth, slightly biexcavate apically; abdomen scarcely 

 (except slightly towards the base) carinate ventrally. Connexiva 

 vertical in apterous form, and much narrowed in from the base at first, 

 afterwards continuing subparallel. Maciopteroxis form : pronotum 

 produced basally in a long stout process, which is about equal in 

 length to the space between its origin and the humeral angles of the 

 pronotum. It arises at an angle of about 45°, curves around near its 

 apex, and is then deflected downwards slightly. Elytral neuration 

 feebler than in the male. 



Habitat, (a) Rio Cobre, Spanish Town, St. Catharine, Nov. 

 7th, 1892 ; clear water — no surface growth — sluggish current; 

 taken close to bank of river, {(i) Black River, Elysium Estate, 

 Portland, April 4th, 1899 (C. B. Taylor). 



Black ; the posterior and intermediate femora and tibiae slightly 

 greenish blue (metallic lustre), furnished somewhat sparsely (more 

 densely on the nota) with pale gold pubescence. Base of first antennal 

 segment, base of anterior femora and anterior margin of pronotum, 

 ventral surface of ambulacra, coxae, trochanters (usually), &c., pallid 

 testaceous. Teeth of posterior femora pallid except at apex. Dorsum 

 of abdomen shining black, connexivum rufo-testaceous; ventral surface 

 usually bluish grey (often greatly rufescent), except the brownish 

 genital segments. 



The male of this tine little species, which I have much 

 pleasure in naming after its discoverer, is readily distinguishable 

 from the same sex of all the other American species of the genus 

 by the dilated anterior tibiae, except R. collaris (Burm.), in which 

 the posterior tibiae are notably sinuate. I think also that the 

 form of the sixth (? seventh) abdominal segment in the male is 

 different from that of any other species. 



The type of R. tayloriella is the winged male individual. The 

 species is probably that recorded by Johnson and Fox as R. 

 collaris (Burm.) in 1892, Ent. News, iii. p. 60. [See alsoEntom. 

 1899, p. 30, No. 10.] 



16. Microvelia sp. 



A macropterous individual and two nymphs of a species I 

 have not yet been able to identify.
