which (besides the size) differ from the ordinary foi-m of 

 S. puhicollis in having the thorax nearly black (with red- 

 dish margins), the posterior angles rectangular, and the 

 surface is much more even, the discoidal part being 

 strongly punctured; the front margin and the sides corru- 

 gated as in the typical form. The thorax and under 

 surface of the body are, moreover, scarcely pubescent, but 

 this may be the result of accident. 



Stigmodera tibialis, sp. nov. 



Subtus ferea, rugoso-punctata ; thorace nigro-a3neo, cre- 

 bre punctato, latei'ibus rotundatis ; elytris rufo-piceis, mar- 

 ginibus fasciis tribus apiceque flavis ; tibiis intermediis 

 basi triangular iter dilatatis. 



Long. 21—24 lin. ; lat. 9— 10^ lin. 



Closely allied to St. Stevensii, but at once separated 

 from it by the unicolorous thorax, which has the sides more 

 rounded ; by the abdomen being bronzy, and by the trian- 

 gular dilatation on the intermediate tibi^ ha\dng its apex 

 acute.

Stigmodera sepiemguttata, sp. nov. 



Viridi-aurea, depressa ; thorace valde transverso, crebre 

 fortiter i^unctato ; elytris thorace paululo latioribus, apicem 

 versus arcuatim acuminatis, apice breviter quadrispinosis, 

 testaceis, sanguineo-marginatis, maculis septem viridibus. 



Long. 5 lin. ; lat. 21 lin. 



Allied to 'S'. vicina of Hope, but having the general 

 appearance of *S'. miistelamajor, Thomson. The head is 

 thickly punctured. Thorax posteriorly twice as broad as 

 its length, as narrow as the head in front, gradually 

 widening for about four-fifths its length and then rounded, 

 not very convex, moderately thickly and distinctly punc- 

 tured, strongly and rugulosely punctured at the sides. 

 Elytra a little broader than the thorax, depressed, sinuate 

 at the sides, broadest a little behind the middle, and then 

 narrowed somewhat abruptly to the apex ; each elytron 

 furnished at the apex Avith two equally short spines, pale 

 testaceous, margined with red, strongly punctate-striate ; 

 the interstices very convex, sparingly and very delicately 

 punctured ; there is a round green spot below each shoulder, 

 and another on the margin a little behind the middle ; there
