Corrections, &c., to No. 1. 



6. Notonecta undulata, Say. 



It is not this species which comes to " light," but a small 

 Gorixa, which will be noticed later on. 



New localities. — "Rain-water tank, Yardley Chase, Oct. 31st, 

 1899 " (leucochroic forms). Mr. Taylor writes me : — " Owing to 

 the peculiar geological formation of the district there are abso- 

 lutely no rivers or streams of any kind in the Santa Cruz Mts., 

 the inhabitants depending entirely on rain water for all their 

 needs. For this purpose large tanks are constructed, the water 

 being conveyed from the roofs of the houses and from the 

 ' barbecues '—as the cemented terraces used for drying coffee 

 and pimento are termed — by gutters of various constructions. I 

 did not therefore expect to get any bugs, especially as owing to 

 the severe and protracted drought most of the water supply had 

 been used up, and the tanks were very low in consequence. 

 About a week before my return home, however, the island was 

 visited by a hurricane and series of floods that filled up all the 

 tanks, but wrought incalculable damage to property all over the 

 country. . . . Some idea of the extent of the downpour may be 

 gathered from the fact that a large lake some miles in extent has 

 formed among the mountains to the west of the Santa Cruz 

 range, and at the present moment is increasing to the great 

 consternation of the inhabitants of the surrounding district. In 

 parts this body of water is seventy feet deep. ... I went the 

 round of the tanks. . . . Some plants (known here as the water 

 hyacinth) have almost entirely covered the whole surface, but a 

 small space of clear water at one end was occupied by quite 

 a large number of Notonectas." (C. B. Taylor, Dec. 5th, 1899, 

 in litt.)\ 



9. " Trocliopus plumbeus (Uhler) " = ma?-imis. Carpenter. 



This species was included on the authority of Mr. Carpenter's 

 description. Since writing the first note I have examined the 

 types of Prof. Uhler's and Mr. Carpenter's insects, as well as 



* See "On some Aquatic Ehynchota from Jamaica," Entom. xxxii. 

 pp. 28-30 (1899). 



f I admitted the name '■• maculata'' for a var. of N. undulata in my 

 revision of the genus (1897, Trans. Ent, Soc. Lond. p. 410) : as, however, 

 the name was previously used for a var. of N. glaiica (p. 419), it must be 

 altered, and I now propose " selene." For the cream-coloured forms (head, 

 pronotum, scutellum, elytra, &c.) common in Jamaica, it may be useful to 

 use the name " albida."
