testaceous ; the entire upper surface very densel}', the elytra rugosely, punc- 

 tate, the punctures ou the latter rather coarse aud transversely confluent (the 

 surface thus appearing- very rugose, especially in the depressed post-scutellar 

 area), the under surface densely, extremely minutely punctate. Head excavate 

 on each side anteriorly, the eyes large; antennae long, pilose, joints 2 and 3 

 short, equal. 4-11 elongate, filiform, rather slender. Piothorax very short, un- 

 even, deeply hollowed in front opposite the eyes, arcuately narrowed from the 

 base, the anterior angles prominent, rounded, the hind angles obtuse, the disc 

 canaliculate anteriorly. Scutellum somewhat convex. Elytra broadly arcuato- 

 explanate at the sides, transversely depressed behind the sculellum, and with 

 the suture gibbous before the middle ; each elytron with tliree incomplete 

 costae on the disc, the apices unimpressed. Posterior coxae without angular 

 plate at the base. Posterior femora extremely broad, the tibiae long, curved, 

 broad, and strongly compressed, the outer carina conspicuous, the upper spur 

 nearly as long as the first tarsal joint. 



Length 4f, breadth 3|- mm. „ 



Hah. Perak {Doherty, ex coll. Fry : type) ; Borneo, Sarawak 

 (^A. H. Wallace^ in Mus. Oxon.). 



Two females, precisely similar, each with the ovipositor extruded. 

 A very peculiar insect, resembling a rugose, hairy Coccinellid. The 

 species may come near the Javan forms placed by Pic under JExo- 

 chomoscirtes (1916), which, however, is said to have very prominent 

 anterior angles to the prothorax. 



20. — Ora gibhosa, n. sp. 



$ . Extremely like O. rugosissima from Borneo and Perak : piceous 

 above, the lateral and basal margins of the prothorax, several small, scattered, 

 indistinct ^pots on the basal half of the elytra (one ou the suture below the 

 base the most conspicuous, the two oblique basal streaks altogether wanting), 

 the outer margins of the latter anteriorly, and the posterior tibiae and tarsi, 

 testaceous ; antennae more slender, slightly infuscate, joints 1-3 excepted, 

 3 very small : prothorax uneven, without trace of median groove ; elytra with 

 the punctures separate one from another, and slightly coarser, the common 

 post-basal depression large and deep, the space behind it gibbous, the apices 

 with a smooth, shallow, rather large fovea near the suture before the tip (of 

 which there is no trace in 0. rugosissima, $ ), the disc with four feeble costae, 

 the suture also thiclcened ; posterior coxae without plate ; upper posterior 

 tibial spur shorter than the first tarsal joint. 



Length 3|, breadth 3 mm. 



Hah. Borneo, Sarawak {A. B. Wallace, m Mus. Oxon.). 



One specimen, probably captured at Sadong. Easily separable from 

 0. rugosissima, $, by its much less rugose, obscurely flavo-punctate 

 elytra, with foveate apex, and the more slender antennae.
