Mr. J. 8. Baly on the Phytophaga. 295 



ba>al half of auteuii?e auci legs obscure riifo-fulvous, outer half of 

 anteunoe black. Thorax nearly three times as broad at the base as 

 long, sides naiTowly margined, narrowed and slightly rounded from 

 the base to the apex, more quickly rounded near the anterior angles ; 

 upper surface smooth and shining, remotely covered with minute punc- 

 tures only visible under a lens. Scutellum semiovate, chalybeate. 

 Elytra broader than the thorax, their epipleural margin slightly pro- 

 duced ; surface of each impressed with eleven regular rows of fine 

 punctures, the first abbreviated ; the interstices smooth, impunctate ; the 

 larger irregular cupreous patch covers nearly the whole of the inner 

 disk. 



Fam. Gallerucidse. 



Genus Adorium, Fabr. 

 Adorium collaris. 



A. ovatum, convexum, nigrum, subnitidum ; abdominis apice thoraceque 

 pallide fulvo-flavis ; anteunis brevibus. — Long. 6 lin. 



Hab^ Lake N 'Garni. 



Regularly oval, black, subnitidous, nitidous beneath ; apical segment 

 of abdomen, together ■ssdth the entire thorax, pale fulvous ; sides of the 

 latter margined and rounded, their anterior angles slightly produced ; 

 the upper surface excavated, finely but not closely punctured. Elj'ira 

 ovate, acutely roimded at their apex ; sides narrowly margined ; upper 

 surface closely covered with deeply impressed pimctiu-es. 



Adorium ornatum. 



A. oblougo-ovatmn, convexum, nigi'um, uitidum ; thorace femorumque 

 basi fulvo-flavis ; abdomine elytrisque testaceis, his subcrebre pimctatis, 

 fascia lata basali et utriusque macula transversa pone medium nigris. — 

 Long. 5 lin. 



JIab. New Guinea. 



Antennfe more than three-fom-ths the length of the body, moderately 

 robust, gi'adually tapeiing towards their apex, the third and fourth 

 joints slightly elongate, nearly equal, three basal joints fulvous beneath. 

 Sides of thorax slightly rounded, somewhat naiTowedand subsinuate in 

 front, upper surface impressed with irregularly crowded punctiires ; 

 pleurae stained with fulvous ; abdomen paler than the elytra, clothed 

 with fine adpressed pubescence. 



Nearly allied to A. riibrum, Blanch. ; but in that insect the whole 

 surface of the body (the fuscous outer half of the antennae and the 

 black markings of the elyti-a excepted) is a bright uniform testaceous 

 red : the arrangement of the markings is similar to that of the present 

 insect, with the exception that here the basal fascia is abbreviated 

 on the extreme lateral border, and the spot on the hinder portion of 

 each elytron is much larger, forming an irregular rotundate patch ;
