Measurements. Female (n=2): TL= 3.7 mm, HW= 0.8 mm, PL= 0.7 mm, PW= 0.8 mm, EL= 2.3 mm, EW= 0.9 mm. Ratios PL/PW= 0.87, HW/PW= 1 and EL/EW= 2.55

Diagnosis. Head, antennal segments IV and V, palpi, pronotum and legs yellowish brown. Terminal segments of the antenna brown. Head width same as pronotum width. Elytra matt black, a fairly large humeral band, one round spot next to the side edge near the center and a quadrangular spot near apex before bright reddish yellow elytral apex. Legs light yellowish brown.

Distribution. This species was reported from Rawalpindi ( Jedlička 1963) . During our current study it has been collected from Islamabad area after a hiatus of more than 50 years.

Comments. The species resembles to M. florida Andrewes, 1924 in that the humeral band is very narrow and uneven, the tarsus, knees and underside are dark, the antenna only has I–II segments yellow red and the head is densely punctuate. Elytra are similar to those of M. moesta Schmidt –Goebel, 1846, but the apical rounded white mark near suture area is divided into two separate marks; head and pronotum are black, legs brownish-yellow; knees are blackish, while ventral side of the body is dark brown ( Jedlička 1963).
