334 Mr. G. C. Champion on various African 
17. Laius semilimbatus. 
3. ? Laius semilimbatus,Pic, Mélanges exot.-entom. xviii. p. 14 (1916). 
?. Elongate, rather narrow, slightly widened posteriorly, 
shining, clothed with fine, decumbent, pallid pubescence 
intermixed with long, erect hairs; black, bluish-black, or 
nigro-violaceous, the antennal joints 1 and 2 in part 
testaceous, the prothorax with the anterior margin rather 
broadly, and the elytra with a common, anteriorly-excised 
fascia before the middle and a narrow one near the apex, 
which are connected along the suture, rufous or testaceous 
(leaving a posteriorly triangulate basal space, the apex, and 
a broad oblique patch on each elytron, metallic or black) ; 
the head closely, very finely, the lateral portions of the 
prothorax densely, rugulosely, and the disc of the latter 
sparsely, punctulate, the elvtra somewhat densely and not 
very coarsely punctured. Head rather broad, impressed in 
the middle between the eyes, the latter prominent ; 
antenne long, joints | and 2 elongate, moderately thickened, 
subequal in length. Prothorax about as long as broad, 
convex, constricted and much narrowed towards the base, 
the disc excavate on each side anteriorly, the transverse 
basal depression deep. EHlytra long, much wider than the 
prothorax. 
6. Antennal joint 1 very stout, curved, concave externally; 
2 enormously large, concave, somewhat ear-shaped, truncato- 
dilatate and furnished with a broad, curled, membranous 
appendage on its inner aspect (Pl. VIII. fig. 13); 3-10 
moderately elongate, 
Length 33-4 mm. (3 ?.) 
Hab. Tonxrn | type of Pic], between Vientiane and Luang 
Prabang, Laos, Ban Saleun (Salvaza). 
Found in abundance in each locality by Mr. R. V. de 
Salvaza at the end of 1919 and beginning of 1920, the long 
series sent by him to the British Museum including nine 
males. The elytral fascize vary in colour from bright red to 
pale testaceous. This species agrees with the diagnosis of 
L. semilimbatus, Pic, except as regards the sculpture of the 
prothorax, which is said to be “‘fere impunctato”’; butit is 
possible that some mistake has been made in this respect. 
If a new specific name is required for the insect before me, 
rufolimbatus can be used for it.
