ISCHIOPSOPHA RITSEMAE. ISS 



attenuata , apice rotundato , suhemarginato , sutura spinosa ; 

 ad margines suturamque strigosa , in disco tenuiter punctata , 

 quae sculptura basin versus evanescit. Pygidium valde strigo- 

 sum , carina media acuta , subfus in medio fortius excavatum. 

 Mesosterni processus apice subreclinato. Abdominis zona stri- 

 dens tenuis; latera sterni strigosa] pedes nigro-ciliati; tibiae 

 anticae fortiter bidentatae. — Long. 29 mm., lat. 14 mm. 



Dark golden green , very brilliant. Head sparingly punc- 

 tured , the punctures more closely set at the lobes , chang- 

 ing into fine striae. 



Prothorax broad, subconvex, with the sides rounded, the 

 posterior angles somewhat inward directed, obtuse, the median 

 lobe broad , truncated at the top in a slightly curved line ; 

 smooth on the disk, very finely and distantly punctured 

 near the lateral and fordermargins , broadly strigose along 

 the sides; above the posterior angles a small round impres- 

 sion may be seen and also in the middle of the median 

 lobe a shallow V-shaped one. 



Scutellum rather broad. 



Elytra gradually attenuated towards the apex, which is 

 rounded and very slightly emarginated, the suture is armed 

 with an unusual strong spine; strigose along the outermar- 

 gins , commencing below the shoulders , and along the suture 

 up to the middle, a few shallow punctures on the disk, 

 the whole sculpture decreasing towards the base, which is 

 quite smooth. 



The pygidium finely and densely strigose, the median 

 carina very sharp , above with a faint trace of a longitudinal 

 median ridge, below deeply excavated, more strongly in 

 the middle. 



The mesosternal process straight, hardly incurved at the 

 tip; the stridulating organs of the abdomen feeble; the si- 

 des of the breast shallowly strigose; the legs with black 

 hairs, the anterior tibiae with two strong teeth. 



I. Ritsemae belongs to the broader species and is to 

 be placed near I. virens Homb. & Jacq. and /. d'Urvillei 

 Burm.
