In the présent collection many spécimens of entirely différent 

 markings together with the tjpical forms has proved to me that 

 mj spécimens were varieties and that the apparently normal 

 form is as foUows : 



Dark metallic blue, closely pubescent, above fulvous, thorax 

 with two transverse semicrescent basai spots, elytra with a 

 transverse band before and another below the middle, black, 

 tibiae and tarsi fulvous. 



var. a. Thorax unspotted or very obscurely marked, elytra with 

 two spots below the base and a narrow transverse band below 

 the middle, black. [G. sexmaculata Jac). 



var. h. Thorax and elytra entirely fulvous. 



AU thèse forms were obtained at Tharawaddy in Burmah, the 

 banded one resembles entirely D. Dejeani Lac. except that the 

 thoracic band of that species is replaced by two broad curved 

 spots, but both species may be separated by several points of 

 distinction : m D. Dejeani the head is smooth and shining 

 excepting between the eyes, in the présent insect the clypeus is 

 finely strigose or punctured and the labrura is fulvous, the 

 thorax instead of having a transverse black basai band has two 

 curved spots at the sides, the scutellum is small and narrow, 

 and the elytra are strongly punctured in D. Dejeani^ while hère 

 the scutellum is broad and triangular and the elytra are very 

 finely punctured. D. quadrimaculata o( thls paper is again simi- 

 larly marked but is altogether smaller and narrower and has a 

 longer thorax ; in the Bhamo spécimens the legs are entirely 

 fulvous, in those obtained by M' Andrewes, they are either 

 bluish-black or with the tibiae and tarsi fulvous. I think that 

 the species must find its place in Diapromorpha. 



Diapromorpha quadrimaculata n. sp. 



Black, pubescent, thorax impunctate, fulvous with two 

 crescent-shaped black bands, elytra closely and strongly punctured, 

 fulvous, a transverse spot on the shoulder and a subquadrate 

 spot below the middle, black. 



Length 2-2 i/a lines. 



Of parallel, subcylindrical shape, the head black, very 

 finely rugose and pubescent between the eyes, clypeus finely 

 punctured, labrum and palpi black, antennse black, the lower 

 three joints more or less fulvous, the fourth and following 

 joints strongly transversely serrate; thorax more than twice 

 as broad as long, narrowed in front, subcylindrical, the sides 

 strongly deflexed, the latéral margin nearly straight, the angles 

 distinct, the surface with two narrow oblique obsolète dépressions
