104 APOGONIA WATERSTRADTÏ. 



the middle, larger and closer set towards the sides ; in 

 front of the scutellum the punctures are very small and 

 more widely spread ; a not very obvious smooth line runs 

 along the middle of the pronotum; the anterior angles 

 are acute and slightly projecting; the sharply margined 

 sides (viewed laterally) are strongly curved behind the 

 middle ; the posterior angles are very obtuse. The scutel- 

 lum is broadly triangular, impunctate or with a few al- 

 most imperceptible punctures. 



The punctuation on the elytra agrees with that of abdo- 

 minalis but the punctures are somewhat stronger; the two 

 impressions behind each shoulder are, however, a little less 

 distinct, especially the anterior one. There are on each 

 elytron three costae : the first, which bears two irregular 

 rows of very fine punctures, is broad but becomes nar- 

 rower anteriorly and posteriorly ; on the middle of the 

 elytra its width surpasses a little that of the following 

 interspace; the 2 nd costa is distinctly narrower and bears, 

 like the 3 rd costa which is still narrower, a series of very 

 fine punctures; outwards from the 3 rd costa there are three 

 lines of punctures : the outermost is marginal and the in- 

 nermost joins the 3 rd costa just beyond the shoulder; the 

 interspaces between the 3 rd costa and the margin are about 

 of equal width and show a row of punctures which are 

 very distinct on the innermost interspace, almost imper- 

 ceptible on the two following ; the interspace between the 

 2 nd and 3 rd costa bears a row of distinct punctures which 

 is irregular on the basal half, very regular on the apical 

 half of the elytra ; the interspace between the 1 st and 

 2 nd costa has likewise a row of distinct punctures which, 

 on the contrary, is regular on the basal half, irregular 

 on the apical one ; the interspace between the sutural row 

 of punctures and the 1 st costa is rather sparsely punctured 

 in an irregular manner. Behind each shoulder two impres- 

 sions may be observed: the anterior one, just behind the 

 shoulder, is not very distinct ; the 2 nd , situated on the outer 

 boundery line of the 3 rd costa, is smaller but more distinct.
