PHYTol'IIAGA FROM SUMATRA 491 



long, tMHUil, basal joint curvol and thickened at the apex, tho- 

 rax about one half broader than long , the sides straiglit and 

 narrowed at the base, slightly but rather suddenly widened in 

 front, the angles distinct, anterior and posterior margins straight, 

 the disc deeply bifoveolate at the middle, impunctate, sculellum 

 broader than long , elytra parallel , elongate , strongly costate 

 throughout, each elytron with seven or eight costae, the inter- 

 spaces not perceptibly punctured, legs slender, the first joint of 

 the posterior tarsi much longer than the following joints together, 

 claws appendiculate, anterior coxal cavities closed. 



Hah. Si-Rambé. 



Several other species, placed in this genus, have been described 

 by myself from the Malayan region, the type was founded by 

 Baly on a species from India ; the genus comprises species re- 

 sembling those of Aulacophom but the claws are appendiculate, 

 the elytral epipleurae continued and the anterior cavities are 

 closed; the present species resembles slightly 31. subcostala, Jac. 

 likewise from Sumatra but the elytra in the insect before me 

 are much more strongly costate and the interstices are scarcely 

 punctured but show small piceous spots ; in the specimen which 

 seems to be the male and which is smaller than the females, 

 the second joint of the antennae is extremely small, the corres- 

 ponding joint in the other sex is rather larger, I am only able 

 to discover a spine at the intermediate tibia in the male , but 

 in the females, all the tibiae have a distinct long spine, other- 

 wise there seem to be no differences between the two sexes. 



152. Theopea Modiglianii, n. sp. — Reddish-fulvous, the lower 

 joints of the antennae, the apex of the tibiae and the tarsi more 

 or less black, thorax subquadrate, bifoveolate, elytra violaceous 

 blue, closely punctured and transversely rugulose. 



Length 2 ^2"^ lines. 



Head impunctate, the frontal elevations strongly marked, tri- 

 gonate, palpi piceous, antennae long and slender, pubescent, 

 black , the basal joint fulvous at the base , rather slender , the 

 second one very short, third and following joint of nearly equal 

 length, the last four joints yellowish white, thorax not longer
