Cosmoscarta ignifera, sp. n. 



Head, pronotuin, and scutellum deep dark olivaceous, body beneath 

 and abdomen above bluish-black ; basal areas of the abdominal 

 segments above and legs brownish ; tarsi piceous ; head with a 

 central frontal ochraceous spot extending over base of face ; tegmina 

 brownish -ochraceous with seven pale ochraceous spots, two one above 

 the other near base, two similarly placed about one-third from apex, 

 the other three situate between the two series ; wings smoky hyaline 

 more or less roseate at base. 



Pronotum deeply foveate on each lateral area, its posterior margin 

 subacutely sinuate, its lateral margins slightly refiexed, its surface 

 obscurely and finely punctate, with a posterior central carination ; 

 scutellum broadly and deeply foveate at base ; face compressed and 

 somewhat angulate at apex ; posterior tibiae with a very long spine 

 about one-third from apex. 



Long. excl. tegm. 10 millim. Exp. tegm. 29 millim. 



Habitat. Borneo, Kuching (Shelford — Coll. Dist. and 

 Sarawak Museum). 



Apart from markings, the structure of this species is 

 very peculiar. 



Cosmoscarta menaca, sp. n. 



Ochraceous ; metanotum, fourth and fifth abdominal segments 

 above and sometimes the base of the third, sternum and basal areas 

 of the segments beneath, piceous ; lateral margins of prosternum 

 piceous ; tegmina ochraceous, apical fourth densely reticulated, with 

 five black spots — two in clavus and three discal — sometimes with 

 appearance of a sixth before reticulated area, and again sometimes 

 with only one in claval area. 



Pronotum dilated on each side, the lateral angles rounded, the 

 posterior margin truncate, the margins refiexed and with a distinct 

 central carination, its surface is very finely wrinkled and punctate ; 

 face very prominent and compressed ; posterior tibias spined at about 

 one-third from a2jex. 



Long. excl. tegm. 15 to 16 millim. Exp. tegm. 40 to 42 millim. 



Habitat. British India, Assam (Atkinson' Coll. — Brit. 

 Mus.), North Khasia Hills (Chennell— Coll. Di.st.) ; 

 Binding Isle (Ridley — Brit. Mas.); Borneo, Matang 

 Mt., 8200 ft. (Shelford— Sarawak Mus. and Coll. Dist.).
