LONGICORN COLEOPTERA FROM BURMA 39 



Guérin-Méneville (Voy. Delessert, Vol. II (1843), p. 59), who 

 proposed for it the name Macrochenus , Pascoe subsequently 

 (Proc. Zool. Soc. 1866, p. 252) described it under the name of 

 Mecotagus, by which it has since been generally known. M. tes- 

 sellatus, Guér. (1. c), the type of the genus, is probably iden- 

 tical with, or, at most, a variety of M. tigrinus, Oliv.

One example taken at Carili Mts. (district of Ghecù) at an 

 altitude between 1300 and 1400 metres. The species occurs 

 also in Siam. 



The pale green scaly pubescence of the elytra in this example, 

 instead of being arranged in regular transverse bands, as in 

 the type (with which , through M. René OberthiJr's kindness , 

 I have been enabled to compare it) is broken up into spots , 

 of which the first series consists of three, oblong or quadrate, 

 near the base of each elytron, the second of two on each ely- 

 tron — one, smaller, lateral, the other larger and transverse, near 

 the suture; the third row is made up of one large transverse 

 spot towards the side of each elytron, and of two smaller spots 

 on the left elytron and one on the right elytron , near the 

 suture ; the fourth row consists of two spots on each elytron — 

 one, large, transverse, towards the sides, one, smaller, close to 

 the suture. This row is succeeded by a large spot at the apex 

 of each elytron. In its remaining characters the specimen agrees 

 well with the type. 



There is an example from Siam in the British Museum col- 

 lection , in which the third and fourth bands of the right ely- 

 tron are broken into spots near the suture, and exhibit a want 

 of symmetry in relation to the bands of the left elytron. It is 

 probable , therefore , that a considerable amount of individual 

 variation exists with regard to the arrangement of the pube- 

 scence in this species.
