I have identified this species with some doubt. All the specimens 

 that were collected were preserved in alcohol, and in this state the mark- 

 ings, especially those on the elytra, appear more distinct than those 

 in pinned specimens, in which they have a tendency to fade or become 

 discoloured. In the alcohol specimens there is a distinct interruption 

 in the ochraceous band at the anterior margin of the j)ronotum, whereas 

 in the pinned specimens in the collection of the Zoological Survey of 

 India this band appears to be entire, and is also figured as such by Dis- 

 tant in his description of the species. Furthermore, the colour of the 

 antennal joints and that of the underside seem to vary to a very marked 

 degree in the specimens in alcohol. 



A. large number of specimens, in all stages of development, were taken 

 on the surface of a small puddle at the foot of Elephant Hill, near Yawn- 

 ghwe, 17-ii-1917, and two specimens from the surface of the marginal 

 zone of the Inle Lake, 2 — 3-iii-1917. This species has been recorded 

 from Calcutta and Rajshahi in the Province of Bengal.

A single specimen (preserved in alcohol) of this species was obtained 

 on a. small stream at Hsamonghkam (Thamakan) 4,000 — 4,500 feet, 

 Southern Shan States, 13 — ll-ii-1917, and a few from the Taung-gya 

 Valley, Yawnghwe State, ca. 3,500 ft., 2-iii-1917. 



I cannot identify this species with any described form. It resembles 

 M. albomacidata most closely, but the position of the spots on the elytra 

 is a httle different, the relative length of the antennal joints and the 

 colour of the legs, antennae and the underside are also different. 



I have compared the Shan specimens with some specimens of M. 

 albomaculata identified by Distant. The length he gives in his descrip- 

 tion of the latter is 2 mm., but the specimens he has identified are con- 

 siderably smaller. The Shan specimens, though actually much larger 

 than those of M. albomaculata, measure only 2 mm. in length. 



In general colouration this species is very like M. albomaculata, 

 A series of small deep black spots is situated within the marginal pubes- 

 cent fascia near the inner margin of each eye, and there is a longitudinal, 

 impressed, black line on the disk of the head not continued to the base 

 or apex. The antennae are hairy, brownish ochraceous ; the greater 

 part of the basal joint posteriorly is much paler ; the first joint is stout, 

 curved outwards, longer than the second which is the shortest joint ; 

 second joint stout at apex and tapering at base ; the third joint is slender, 

 long, a little longer than the first ; the fourth joint is very long, slender, 

 about as long as the second and third together ; eyes black. 



The pronotum is as in M. albomacidala, except that there is a dis- 

 tinct, deep black, discal, longitudinal line extending from the anterior 

 fascia to a little beyond the middle.
