9 
vitta uniting broadly near the apex with a narrow lateral 
marginal vitta, a humeral dark spot and an elongate spot 
in the middle of each elytron sometimes becoming a vitta 
that does not extend to the base. 
Head pale with deeper brown mouthparts, finely punc- 
tate, eyes nearly meeting on the occiput. Antennae pale 
brownish with the three basal joints yellowish. Prothorax 
twice as broad as long at base with thickened apical angles, 
finely and densely punctate, sometimes very faintly 5- 
spotted. Elytra a little more shining, distinctly and rather 
densely punctate, pale with deeper brown markings in the 
form of a sutural vitta uniting broadly at apex with a 
lateral marginal vitta, also a spot on humerus and a 
median elongate spot, sometimes becoming a short median 
vitta. Body beneath yellowish or reddish brown with 
paler tibiae and tarsi. Length 2.6-3.5 mm.; width 1.7-2 mm. 
Type data. — Holotype male (U.S.N.M. Cat. No. 60,932), 
and four paratypes from Tucuman, Argentina, collected 
Oct. 11, 1925 by G. F. Moznette. 
Other material. — In the U.S.N.M. : Argentina : 4 speci- 
mens from Santiago del Estero, collected April 13, 1940 by 
H. L. Parker, 6 specimens from Betania de Salta collected 
in a citrus grove May 13, 1927 by M. Kisliuk. In M.C.Z. in 
Bowditch collection : 1 specimen from Tucuman Prov. 
collected by C. Bruch, 1 from Jujuy, 2 from Catamarca 
Prov., C. Bruch, all these from Argentina. One specimen 
in collection F. Monros collected at Tarija on Rio Bermejo, 
Bolivia, Oct. 20, 1948 by A. Marlinez. 
Remarks. — This is another species closely related to 
M. vandepolli Duv., but distinguished by the dark lateral 
vitta and the slightly differently shaped aedeagus. It is 
a paler species also, being yellow brown and not orange 
brown, and has brownish dark markings instead of black. 
As in the case of M. melanoloma, the median elytral spot 
is more elongate and less triangular, and in some specimens 
in a series from the same locality the median spot is 
lengthened to a vitta, which, however, does not extend to 
the base. So far specimens have been seen only from the 
northwestern part of Argentina and from Bolivia.
