Originally described as an immigrant into. Hawaii, it is now- 

 recorded from the whole of Eastern Australia (at least) and the 

 lowlands of Fiji. 



The ova are not remarkable, b^ing of the usual Phr\nomor- 

 phine type of Grass-feeder and are inserted in the usual way in 

 the leaves of Cynodon dactylon (the "Dog's tooth grass " of Eng- 

 land, and the "Maniania" of the Hawaiians). 



The last nymphal instar (PI. i., f. 13) is of the form of the 

 adult, pale testaceous, with 4 olive-brown longitudinal lines, the 

 2 lateral terminating anteriorly at the eyes. There are about 24 

 black bristly hairs, 3 on almost each segment, arranged in 3 

 longitudinal rows, one submedian, one sublateral and one lateral. 

 The anterior margin of the vertex is narrowly white with faint 

 fuscous marks and a very narrow anterior line of fuscous. Frcns 

 with fuscous transverse lines from a pale central line, on the basal 

 third. Clypeus faintly fuscous ; labium black-tipped, reaching to 

 the fore trochanters. Femora brokenlv banded with dark fus- 

 cous or blackish, tibiae and tarsi dark fuscous or blackish at base 

 of some of the bristles (especially the larger ones). The 2 or 3 

 apical abdominal segments laterally fuscous. Eyes greenish. An- 

 tennal flagellum reaching to about the middle cc.xa. 



The other nymphal instars do not differ apprecial)ly except 

 that the frons is pale. 



4. chhvippc, sp. nov. 



Very similar in appearance to Dcltoccplidus abdoiiiiiialis 

 (Fabr/). 



Bright yellow, tegminal veins concolorous. Frons pale 

 brownish, obscurely suffused with darker tint, and with slender, 

 concentric, curved, dark fuscous lines. Genae, lora, clypeus, 

 &c., pallid, the last named a little fuscate medianly. Metanotum, 

 sterna, (mostly) and basal half of abdomen above and beneath 

 (except the lateral margins) blackish. Basal half of fore and 

 middle femora blackish, hind femora dorsally black (except 

 apex), hind tibiae longitudinally lined with black. Vertex tri- 

 angular, as long in front of the eyes as behind, wider than long.
