28. Ukopl.vta rugata, n. sp. (Plate XXK. fig. 15.) 



U. sordidejiaua, depressa ; antennis tiigris, apice ferrugineo, thorace 

 lincis tribiis nigrescentibus ; elijlrls marginibus, sLrigis duabus 

 obliquis fasciaqiie apicali ccneis, humeris triangulariter expla- 

 natis, apice truncato deaticulato, deiite externa acuto ceneo. 



Long. 3| liu. 



Antemise short, longitudinally carinate, the seventh joint with 

 difficulty separable from the eighth. Thorax narrowed in front, 

 very strongly and rather closely punctured ; a median line and oue 

 on each side nearly black. Scutellum pitchy. Elytra with the 

 shoulders triangularly expanded and raised ; the apex denticulate, 

 the outer angle produced into a strong tooth. Each elytron has 

 two very strong shining costie, besides a less marked sublateral one 

 commencing under the shoulder and continued to and along the 

 apical spine. The double rows of punctures in the interstices are 

 very strong and close. Tliere are the following dark bluish aeneous 

 markings — a line over the iiumeral angle, an interrupted oblique 

 dorsal line before the middle, a similar one beiiind the middle, the 

 lateral margin (except at the extreme base and apex), and the apical 

 sj)ine ; there is a brown (ceneous-tinted) line extending from one 

 apical angle to tlie other, and a short line near the apex between 

 the second and third costse. The metasternum has a black line 

 along its lateral margin. 



This species is allied to U. angulata, 01. 



29. Uroplata deplanata, n. sp. (Plate XXX. fig. 16.) 



\] .fernigineo-Jiava ; capite antennisque nigris; thorace linea laterali 

 nigro-ceneo tincta; elijtris cgamo-nlgris, vitta lata communi hand 

 ad apiceni attingenteferrugiaeo-Jlava, ante medium et post 7nedium 

 dilatata, ad apicem truncalis, denticulatis, arigulo exteriio obtuse 

 producto. 

 Long. 3|- lin. 



The antennae have the basal joints shining and sparingly punctured. 

 The thorax is flattened, closely and strongly punctured, witli a well- 

 marked transverse impression on the disk behind the middle, and 

 with a second smooth impression across the basal lobe. Each 

 elytron has three shining costte, the lateral one finer and less strong 

 than the others ; the double rows of punctures in the interstices are 

 very strong and close ; there is a little blue-black, this colour ex- 

 tending a little over the shoulder and about the midde ; the sides 

 are finely and acutely crenulate ; the apex is broadly truncate, the 

 external angle flattened and obtusely produced. The two apical 

 segments of the abdomen are pitchy in the middle. 



30. Uroplata bisi-inosa, n. sp. (Plate XXX. fig. 17.) 



U. nigra; thorace lateribus ferrugineo-flavis ; elytris ferrugineo- 

 flavis, macula scutellari, linea brevi sub humcro, apiceque nigris, 

 hoc truncato, angulo externa in spinam acutam producto. 



Long. 3J lin. 



Thorax very convex, constricted before the anterior angles, which
