Ua-hiuis of India and Java. 459 



formis, Walker, from Dorev, New Guinea (Cat. Hemipt. 

 Het. in B. M., vi., 1878, p.'l<)5). This latter Mr. Walker 

 also described under the name Didich'ms / darifcr {l. c, 

 iv., 1871, p. 170). 



HelopeUis niger, Walker. (PI. XL, fig. 6). 

 The type appears to be a male. It is black, with the antennae 

 (lark brown, the basal joint yellowish brown. The legs are pale 

 brown, with a few darker spots on the femora. The scutellar horn 

 is long, very slightly curved ; light brown, with the extreme base 

 and apex black. 



IlelopeUis hraconiformis, Walker. (PI. XL, fig. 5). 



(^. Black, or nearly so. Antennae brown, with the basal joint 

 pale brown. Scutellar horn long, very slightly curved, very pale 

 brown, with the extreme base and apex dark brown. Legs pale 

 brownish yellow, with a few dusky spots on the femora. 



? . Antenn* dark brown. Thorax hght red, inclined to yellow 

 in front, with the anterior margin black. Scutellum pale red ; the 

 horn very pale brown. Legs dark brown, some spots on the 

 femora and the tibiee paler, but not so pale as in the male. 



General Piebiarks. 



H. Antonii and H. Bradyi will easily be distinguished 

 from the three other species by the form of the scutellar 

 horn, which is small, very slender, and erect. 



//. tJteivora, niger, a,ud hraconiformis have the scutellar 

 horn longer and stouter. H. theivora has the horn much 

 more curved than in either H. ater or hraconiformis. 



H. ater and H. hraconiformis only difi'er in the colour 

 of the legs and antennae, except that the single specimen 

 of ater has the thorax jet-black, whilst both the males of 

 hraconiformis have the base of the thorax smoky brown. 

 The scutellar horn is somewhat different. 



Prof. Westwood, in the note which I received from 

 him, above referred to, states that the specimens he had 

 from the tea-plants in Java, and which he considered to 

 he HelopeUis Antonii, "have the front of the pronotum 

 nearly whitish buff", antennge and head black, scutellar 

 spine dirty buff'-brown, legs buff varied with black." 

 This description does not correspond with any specimens 

 I have yet seen.
