Nilgini Hills, Madura (coll. Andrewes) ; Cryuon (ex Colombo 
Museum). 
Pic’s description, based upon the 9? only, would apply 
almost equally well to two closely-allied Indian insects, 
which have a very differently-formed second antennal joint 
in @, this joint varying but little in shape in the numerous 
examples before me, it being always more or less angulate 
and apparently hooked at the inner basal angle in the 
present species. The name externenotatus is here selected 
for the common S. Indian Lavus allied to L. jucundus, Bourg. 
The completely bifasciate forms must come very near 
L. sikkimensis, Pic (1914). 
23. Laius birmanicus, sp. n. 
?. Elongate, narrow, slightly widened posteriorly, shining, 
clothed with scattered pubescence intermixed with long, 
erect hairs ; black, the antennal joints 1 and 2 in part or 
entirely, and the prothorax, testaceous, the elytra nigro- 
cyaneous or nigro-violaceous, with a common angulate. 
fascia below the base and a narrow one near the apex, which 
are connected alung the suture, whitish or testaceous ; the 
head and prothorax finely, the latter with the sides rugulosely 
and the disc very sparsely, punctulate, the elytra rather 
coarsely, closely punctured. tiead about as broad as the 
prothorax, impressed in the middle between the eyes ; 
auteune with joints 1 and 2 modeiately thickened, elongate, 
subequal in length, 8-10 much longer than broad.  Pro- 
thorax as long as broad, convex, constricted and much 
narrowed towards the base, excavate on each side anteriorly, 
and with a deep basal groove. LElytra long, rounded at 
the tip. 
3S. Elytra subparallel ; antennal joint 1 strongly curved, 
much widened outwards, 2. extremely large, concave, 
obliquely subquadrate, the inner margin produced into a 
backwardly-curved, short, hook-like projection near the 
base (Pl. VIII. fig. 18).

Two pairs. ‘I'he description of the ¢ is taken from a per- 
fect example captured by Mr. Downing; the others are in bad 
condition. Near L. amanus, Bourg. (1891), from Cambodia, 
and L. sikkimensis, Pie (1914), from Sikkim: the former is 
said to have a subglobose 2nd joint to the antenne in 
gd and the pallid posterior elytral fascia reduced to two 
small spots, and the latter to have the corresponding
