length to the second, but the fourth joint, as in the male, is the longest, 

 and the elytra are coarsely punctured ; the general size is also larger 

 and more robust. 

 Dikoya. 



Neochrolea (gen. nov. Galerucinse). 



Body oblong. Head longer tlian broad, the front excavated above 

 and below the antennae ; the latter as long as the body, filiform, the 

 second joint very small, the third the longest, thickened and 

 emarginate below. Palpi thickened at the penultimate joint. Thorax 

 transversely subqnadrate, the disk obsoletely depressed. Elytra 

 scarcely visibly punctured, their epipleurse continued below the 

 middle. Tibiae mucronate. The first joint of the posterior tarsi a 

 long as the two following joints together. Claws appendiculate 

 Anterior coxal cavities closed. 



Neochrolea seems allied to the genus Macrima, Baly, with which 

 it agrees in the closed coxal cavities and the mucronate tibife ; it 

 differs in the long third joint of the antennse and in the less transverse 

 thorax, also in the shorter first joint of the posterior tarsi. The 

 only specimen before me is evidently a male ; and it is probable that 

 the female wants the deep excavations of the head, as is often the 

 case in similar structures in the sexes in other genera, ^nidea, 

 Baly, differs in the unarmed tibiae, 



Neochrolea cavifrons, sp. nov. (Plate XI. fig. 4.) 



Entirely testaceous ; third joint of the antennae emarginate below ; 

 Lead with a deep excavation ; thorax nearly impunctate, the disk 

 obsoletely depressed ; elj tra extremely finely and closely punctured. 



Length 4 lines 



Head longer than broad, impunctate, the space below the antennae 

 deeply excavated, the lower margin of this excavation forming a 

 triangular and pointed flattened projection ; the lower part ot the 

 face again deeply excavated ; the anterior margin of the clypeus 

 produced into two long points; the extreme apices of the jaws 

 black ; palpi thickened at the penultimate joint. Antennae slif^htly 

 longer than the body, fulvous, the second joint extremely short ; the 

 third elongate, thickened, and hollowed out at the lower margin ; the 

 ioUowing joints of half the length, equal. Thorax one half broader 

 than long, narrowed towards the base, the sides very little rounded 

 before the middle ; the surface with a small depression at the middle 

 of the disk, scarcely Tisibly punctured. Elytra rather convex, 

 without basal depression, not more distinctly ])uuctured than the 

 thorax, testaceous like the rest of the insect. 



Balangoda. 



""O^ 



Haplotia (gen. nov. Galerucinae). 



Narrowly elongate. Antennae slender, filiform, all the joints 

 with the exception of the second of nearly equal length ; palpi with 

 the penultimate joint thickened. Thorax square-shaped, obsoletely 

 impressed, rugose. Elytra closely rugose (cj), or simply punctured
