90 MR. M. JACOBY ON THE [Feb. I, 



groove, which extends to the inner margin of the eyes. Antennae 

 nearly as long as the body ; the 4 or 5 lower joints obscure fulvous, 

 the five following ones black, the apical joint reddish fulvous ; the 

 third and fourth joints equal. Thorax transversely subquadrate, the 

 sides straight, the posterior margin slightly lobed, the anterior angles 

 obliquely truncate and slightly thickened ; surface with a deep, 

 strongly sinuate, transverse groove near the base, extending nearly 

 to the j)osterior angles, the latter produced into a tooth ; the disk 

 impunctate, the groove itself with some punctures ; scutellum 

 fidvous. Elytra with a well-marked basilar depression, the shoulders 

 prominent, the disk strongly punctate-striate, the punctuation 

 diminishing towards the apices, the interstices slightly costate near 

 the sides. Presternum rather broad ; the anterior coxal cavities 

 open. 



M. apicicornis resembles greatly several species from the Malayan 

 regions which served me for the establishment of the present genus ; 

 their general appearance is that of a small species of Crepidodera, 

 from which the open coxal cavities and the strongly sinuate thoracic 

 groove separates Manobia. In M. apicicornis, which seems to be 

 a very variable species, the apices of the elytra are pale ftdvous, while 

 the last joint of the antennae is of a more reddish colour ; this is 

 constant in all the specimens before me, and separates the species 

 from its allies, 



Crepidodera hirtipennis, sp. nov. 



Oblong-ovate ; black ; antennae and tarsi flavous ; thorax rugose- 

 punctate ; elytra strongly punctate-striate, the interstices costate, 

 and clothed with long white pubescence. 



Length g line. 



Head not visibly punctured, with some single long white hairs. 

 Antennae a little shorter than the body, the third and the two follow- 

 ing joints equal, slightly shorter than the second but not so stout ; 

 terminal joints slightly thickened, the apical one fuscous, the rest fla- 

 vous. Thorax rather more than twice as broad as long, the sides nearly 

 straight, the disk strongly rugose-punctate, transversely grooved 

 near the base. Elytra with regular rows of deep punctures, the 

 interstices strongly costate, and furnished with long white single 

 hairs. Legs black, tarsi flavous. 



Of this small and interesting little species there is only a single 

 example before me. As the specimen is carded, I am not able to say 

 anything about the state of the cavities or other characters of the 

 underside, and have placed it at present in Crepidodera on account 

 of the thoracic groove and punctate-striate elytra. The following 

 species, of which also only a single specimen was obtained, is still 

 smaller. Both agree in the almost equally stout femora of all the 

 legs, which leaves it doubtful whether these species would not equally 

 well find their place amongst the Galerucinse. 



Crepidodera mintjta, sp. nov. 



Entirely pale fulvous ; head impunctate ; thorax very closely
