188 C. M. F. von HAYEK 
Type-material: 2I[PZAN, Warsaw (Dohrn coll.). 
The generic attribution is based on the following specimen: J, China; Janson 
coll. ex Candéze, 1903.130; Lacon musculus Cdz. China [Cand.]; Lacon musculus 
Cand., ex. coll. Candéze [Gahan] (BMNH). This specimen may be part of the 
syntype-series retained by Candéze. 
Agrypnus mustellinus (Germar) comb. n. 
Lacon mustellinus Germar, 1840 : 264. 
Lacon birmanicus Candéze, 1874: 71. Syn.n. 
Adelocera mustellinus (Candéze) Fleutiaux, 1926 : 96. 
Candéze (1857 : 110) records that he received the ‘exemplaire typique de Germar’ 
of this species from Schaum. The BMNH manuscript catalogue of the Schaum 
collection does not list this species. However the MNHU, Berlin contains a single 
specimen from the Schaum collection (see below). Why this specimen is in Berlin 
while the type-material of species described at the same time (tubidus Getmar 
and tevrenus Germar) are now in the BMNH collection is unknown. There are 
no specimens determined as mustellinus by Germar in the DEI, Eberswalde. 
Lacon mustellinus Germar. LECTOTYPE (present designation). ¢, 43275 
{Museum catalogue number = Siam, ex Schaum coll.]; L. mustellinus Germ. 
[Candéze] (NMHU, Berlin). The specimen stands beside a yellow label in 
Gerstaecker’s handwriting: mustellinus Germ. sec ejus type, Tenasserim Helf. 
The published locality is Stam. The locality Tenasserim refers to a second specimen 
of the same species bearing the number 16113. The absence of Germar’s determina- 
tion label is probably due to Gerstaecker. 
The lectotype agrees well with the description except that the antennae are 
I1-segmented and not 12-segmented as stated by Germar. The last antennal 
segment is a contricted at the apical third and this may have misled Germar, 
whose eyesight was not very good (see p. 275), into believing that the antennae 
were 12-segmented.
