CHRYSOMELIDjI'. 
26. Lema semiregularis, sp. n. 
Fulvous; labrum black; elytra metallic violaceous; underside 
aud legs fulvous. 
Vertex of head triangularly raised, very slightly grooved, the 
base not constricted behind the eyes; labrum black; antennae 
•very long and slender, the third joint shorter than the fourth, 
terminal joints very elongate. Thorax moderately constricted at 
the sides, the anterior portion not much widened, the basal sulcus 
very deep ; the surface impunctate, fulvous. Scutellum fulvous. 
Elytra with a short but rather deep depression below the base 
and there very strongly punctured, with the interstices trans- 
versely wrinkled, the puncturation as usual, gradually liner 
posteriorly yet very distinct. Beneath and the legs fulvous. 
Length 6 mm. 
Hcib. Manipur (Doherty). Type in Brit. Mus. Malabar coast 
(Coll. Jacoby). 
Amongst the fulvous species with blue elytra, the present form 
may be known by the unequal size of the third and fourth joints 
of the antennae and the coarse puncturation at the base of the 
elytra, which looks somewhat confused on account of the trans- 
versely rugose interstices. A specimen with partly black elytra 
does not seem to differ in any other respects, but two specimens 
from Mahe (Malabar) in my collection are rather larger and more 
robust, the vertex is more strongly raised and the punctures at the 
base of the elytra are rather less confused ; but these differences 
do not seem to me important enough to be considered specific. 
27. Lema malabarica, sp. n. 
Rufous ; the antennae (basal joint excepted), clypeus, labrum, 
apex of tibiae and the tarsi black ; elytra metallic blue, extreme 
apical margins fulvous. 
Head impunctate, intraocular space highly raised and deeply 
longitudinally divided ; eyes acutely notched ; clypeus and labrum 
black ; antennae with the basal joint rufous, the following five 
joints black (the rest in the type and only specimen wanting), 
third and fourth joints equal, twice as long as the second joint. 
Thorax broader than long, the anterior portion strongly transverse, 
the angles prominent but not tuberculate ; basal sulcus deep, 
sinuately widened at the lateral constriction but not forming a deep 
excavation nor bounded by a ridge above ; surface with a few- 
minute punctures on the middle. Scutellum fulvous. Elytra 
feebly transversely depressed below the base, closely and deeply 
punctured, the punctures round, the spaces dividing them much 
smaller at the basal portion than the punctures, the latter gradually 
diminishing in size posteriorly. 
Length 5 mm. 
Lfab. Malabar: Mahe (Coll. Jacoby). 
To be separated from other very similarly coloured species 
with black clypeus and labrum by the colour of the tibiae aud the 
tarsi and by the closely approximate large punctures at base of 
elytra in connection with the general size.
