39. Cosmopsaltria opercularis. (Tab. Y., fig. 16, a, h.) 



Dmdubia opercrdaris, Walker, Ins. Saund., Horn. p. 7 (1858). 



As the specimens of this species now contained in my collection have been preserved in 

 spirit, and thus lost their original coloration, I give Walker's original description :— 



"Male. Green, varied with testaceous. Head with a black band, which is interrupted and contains 

 two spots on each side ; front with the usual black streaks. Prothorax with some black marks on each 

 side, and with a testaceous black-bordered stripe. Jlesothorax with a black stripe, which is dilated 

 hindwards, and has a black dot on each side; two incomplete and irregular lateral black stripes. 

 Abdomen testaceous, with a row of black spots along each side; dorsal opercula large, conical; ventral 

 opercula elongate-conical, two-thirds of the length of the abdomen. Wings vitreous, their tips very 

 slightly tiuged with pale brown ; veins green or testaceous, black towards the tips. Fore wmgs with 

 a whitish sUgma; first and second transverse veins clouded with black; first curved, almost upright, 

 parted by more than twice its length from the second, which is oblique; third and fourth hardly 



undulating." 



Long. excl. tegm. 3, 24 to 32 millim. Exp. tcgm. GG to 90 millim. 



Hab!— Malayan Archipelago: Celebes (Brit. Mus. ; Meyer— Dresd. Mus. & coll. Dist.). 



This species not only varies greatly in size, but also appears to be strictly confined 



to Celebes. 



40. Cosmopsaltria lutulenta. (Tab. VII., fig. 7, a, h.) 



Cosmojm,ltri„ lutuLnta, Distant, Ann. Mus. Civ. Gen. ser. 2a, vol. vi. p. 522 (1888). 



Body above dark brownish. Head with the margins of the ocelli, the posterior margins of eyes 

 and a spot on margin of vertex at each side of front, black. Pronotum with two black central marginal 

 spots both on anterior and posterior margins, the incisures also somewhat blackish. Mesonotum with five 

 black fascia;; the central one slender and longitudinal, followed on each side by a short and inwardly 

 curved fascia, the lateral fascia; long, broad and broken; between the two last fascia is a short margmal 

 spot and a rounded spot in front of each anterior angle of the basal cruciform elevation, black. Body 

 beneath pale brownish, the abdomen— excluding anal appendage— darker brown. 



Tegmina and wings obscure hyaline, the venation fuscous, the tegmina with the transverse vems at 

 the bases of the second and third apical areas infuscated. 



The face is long and somewhat compressed, the transverse striations somewhat blackish; the rostrum 

 reaches the posterior cox^ ; the opercula are well separated, concavely sinuate near base, narrowed to and 

 rounded at, apices, which reach the base of the fifth abdominal segment. The third apical area of the 

 tegmina is long and has its base at about centre of upper ulnar area. 



Long. excl. tegm. <? , 28 millim. Exp. tegm. 80 millim. 



Hab.— Malay-vn Archipelago : New Guinea, Salwatty (D'Albertis— Genoa Mus.). 



This is one of the few species captured by Signor D'Albertis during his stay at the island 

 of Salwatty,* and at present our knowledge of the New Guinea Ckadidcc is qmte conhiied to 

 those found in its North-Western Kcgions. I have seen no specimens of the family captured 

 by this naturalist during his explorations of the Fly River. 



* It is more than probable that the insect fauna of Sahvalty is BtiU very little known, as Si?nor D'Albertis had bad 

 health during h>8 risk "It is hardly a fortnight sn.ce we disembarked on thus island with our i^.«r serv-.mts. and to-day all 

 of us w Hhe exception of Beccari, have been attacked by fever."-(D-Albert.s. ' New Gumea, vol. .. p. 441.
