ORIENTAL CI CADI DAL. 75 



This species was probably secured by the Hume Expedition of 1873, which visited this 

 Httle-known island on the return from the Andaman and Nicobar Islands, and of wliich a good 

 account has been given by Mr. V. Ball.' 



13. Pomponia promiscua. (Tab. IX., fig. 14, a, b.) 



Pumpunia jnvmi.'icuii, Distant, Ann. & Mag. Nat. Hist. aer. 5, vol. xs. p. 230 (1887). 



<? . Body above grcenish-ochraceous. Head with two small fuscous spots at apex of front and two 

 wider apaft at base of front, the ocelli also surrounded with fuscous ; the head is mottled with very pale 

 ochraceous, and the eyes are dark castaneous. Pronotum with the margins pale ochraceous, an indistinct 

 central fascia margined with ochraceous, with an obscure castaneous spot on each side, and four oblique 

 incisions on disk, two on each side of central fascia. Mcsonotum with two obscure central obconical spots 

 margined with greenish, the lateral margins and the basal cruciform elevation of the same colom-. Abdomen 

 with the stigmata and the segmental margins castaneous. Body beneath ochraceous ; apex of the rostrum, 

 basal and apical annulations to tibiiB, apices of the tarsi, and penultimate abdominal segment castaneous. 



Tegmina pale hyaline, with talc-like reflexions ; venation alternately ochraceous and fuscous ; costal 

 membrane and a small costal spot at base of upper ulnar area ochraceous, basal claval area greyish 

 opaque ; transverse veins at bases of second and third apical areas slightly infuscated. Wings as tegmina, 

 but unspotted. 



The body is moderately robust ; the abdomen broad, narrowed at apex. The lateral margins of the 

 pronotum are slightly sinuated. The face is broad and tumid, with a central and very obscure levigate 

 carina, but not sulcated ; transverse ridges not extending to apex. Eostrum just passmg the posterior 

 coxre. Opercula small, obliquely rounded, not reaching the basal segment of the abdomen. 



Long. excl. tegm. ,? , 25 millim. Exp. tegm. 65 millim. 



Hab. — Malayan Archipelago: Sumatra (Forbes — coll. Dist.). ENGANot (Doherty — coll. Dist.). 



This species was originally obtained by Mr. Forbes during his natural-history expedition 

 to Sumatra, and the date of its capture was indicated as the month of March. It is probable 

 that the colour is, or often is, green, and not ochraceous, during life. 



14. Pomponia thalia. (Tab. IX., tig. 4, a, b). 



Thmiiuhui th,ili,i, Walker, List Horn. i. p. 72, u. 34 (1850). 

 Pomponia thalia, Stal, Berl. Ent. Zeit. x. p. 171 (18G6). 



Body above ochraceous; head, pronotum, and mesonotum greenish-ocbraceous. Head with some 

 linear streaks on each side of front, the area of the ocelli with a curved linear streak on each side and the 

 inner margins of eyes, black. Pronotum with two central longitudinal black linear fascia% united anteriorly 

 and posteriorly, ampliated and angulated near anterior margin, and compressed and attenuated towards 

 posterior margin, the lateral incisures also black. Mesonotum with seven linear black fasciae, the central 

 longest and straight, with a short and inwardly curved one on each side, again followed by a longer 

 and posteriorly outwardly curved fascia, beyond which is a submarginal fascia (these last were very faint in 

 the specimen figured), and a l)lack spot at apices of each anterior angle of the basal cruciform elevation. 

 Abdomen with a faint, obsolete, central fascia, which is only clearly visible on the two basal segments. 

 Body beneath and legs pale oclu-aceous, with the following black markings : — face with a central 

 longitudinal fascia, a transverse line between eyes and face, and the bases of the posterior tibia^ 



Tegmina and wings pale hyaline, the venation ochraceous and fuscous. Tegmina with an ochraceous 

 and black spot at inner angle of upper ulnar area, and with the transverse veins at bases of second and 

 third apical areas infuscated.
