104 MR. M. JACOBY ON THE [Feb. 1, 



Phyllobrotica marginata, sp, nov. 



Testaceous ; the basal joints of the antennae, the head, and thorax 

 fulvous ; scutellum black ; elytra testaceous, very finely rugosely 

 punctate, the sutural and lateral margins narrowly black. 



Length 2 lines. 



Head impunctate ; the frontal tubercles trigonate, strongly 

 raised. Antennae nearly as long as the body, the third joint double 

 the length of the second, the following ones nearly equal to tlie 

 third joint, the three basal ones fulvous, the rest fuscous. Thorax 

 transverse, more than twice as broad as long, the anterior and 

 posterior margin straight and parallel ; the surface rather deeply 

 transversely depressed, impunctate, shining, fulvous like the head. 

 Scutellum black. Elytra parallel, extremely finely punctured and 

 rugose, the extreme lateral and sutural margins black ; their epipleurae 

 very narrow. Legs slender, the tibiae unarmed ; the first joint of 

 the posterior tibiae as long as the two following joints together ; 

 claws appendiculate ; anterior eoxal cavities open. 



P. marginata differs somewhat from tiie more typical species of 

 the geuus in the more transversely shaped thorax and the distinct, 

 although very narrow elytral epipleurse. In the absence of other 

 marks of distinction, I have placed the species in Phyllobrotica. 



Mimastra capitata, sp. nov. 



Narrowly elongate ; testaceous ; antennae and the breast black ; 

 vertex of the head metallic greenish ; thorax impunctate, depressed 

 at the disk ; elytra finely punctured and rugose, with a metallic 

 green gloss, the margins narrowly greenish black. 



Length 2-3 lines. 



Head impunctate at the vertex, the latter very finely granulate, 

 metallic green or aeneous ; lower part of the face testaceous ; the 

 labrum obscure piceous. Antennae longer than the body, the second 

 joint extremely short, the others very elongate and of nearly equal 

 length ; black, sometimes the basal joints obscure fulvous. Thorax 

 square-shaped, the disk deeply transversely depressed, impunctate, 

 testaceous or fulvous, the lateral margins more or less stained with 

 dark greenish. Elytra finely transversely rugose and closely punc- 

 tured ; testaceous, stained with metallic greenish, the latter colour 

 more distinct at the basal margin ; the suture and the lateral 

 margins also narrowly dark aeneous, which colour extends also to 

 the epipleurae ; the underside either entirely or partially black. 

 Legs fulvous, the tarsi generally fuscous; the first joint of the 

 posterior tarsi as long as the three following joints together ; tibiae 

 unarmed. Anterior coxal cavities open. 



Dikoya. 



Except in the greater length of the posterior metatarsiis, this 

 species does not differ in any other material way from its allies. 



Mimastra robusta, sp. nov. 



Below piceous or blackish ; above fulvous ; antennae and legs
