458 Mr. C. 0. Waterliouse's observations on the 



Helopeltis A7ito7iii. (PL XL, fig. 4). 

 Black. Thorax red, with a blackish line in the anterior con- 

 striction. Scutellum blackish, inclined to red at the sides ; the 

 horn perpendicular, straight, yellowish. Antennae brown ; the 

 extreme base testaceous. Legs dirty yellow, speckled with brown, 



All the specimens I have seen are the same colour, 

 and are therefore probably all females. The males 

 would probably have the thorax black. 



Helopeltis Bradiji, n. s. (PI. XL, figs. 1 & 2). 



$ . Black. Thorax deep red, with the anterior margin black. 

 Scutellum reddish yellow, with the base of the horn black ; the 

 horn perpendicular and straight, yellowish. Antenn£E black, with 

 the extreme base testaceous. Legs black, with a ring of pale yellow 

 at the base of the femora; tibiae brownish. The sides of the basal 

 segments of the abdomen are clear yellow, as in H. Antonii. 

 Length, about 5^ mm. 



The male has the thorax and scutellum black, and the horn of 

 the latter is blackish, with a little brown at the base. The abdo- 

 men has less yellow at the sides. 



This species appears to average a trifle larger than 

 H. Antonii, and the females are a little broader. 



Helopeltis theivora. (PL XL, fig. 3). 

 5 . Black. Thorax orange-yellow, with a black line near the 

 front margin, the base margined with black. Scutellum brown, 

 black at the base, the liorn long, much curved ; black, brown at 

 the apex. Antennae dark brown; the basal joint paler, yellow at 

 the base. Femora dark brown, mottled with light brown, with a 

 light yellow ring at the base. Tibise light brown, speckled with 

 dark brown. 



This species is at once distinguished from the two 

 preceding species by the longer and curved horn on the 

 scutellum. 



Mr. Peal, in his paper on "The tea-bug of Assam" 

 (' Journ. Agri. Hort. Society of India,' iv. (1872), p. 131), 

 states that when full grown "the colour deepens," and 

 " it turns black on the head and thorax." This remark 

 probably refers to the male. 



Two other species of this genus are known to me : 

 Helopeltis niger, Walker, from Waigiou,* and H. hraconi- 



* Not " Wagrin," as printed in the ' Gardeners' Chronicle.'
