14. — SiLHIOMORPHA MACULIGERA. 



Nigra subnitida subtilissimc punctata, elytris leviter striato- 

 punctatis maculfi magna flavii suturali, corpore subtus pecli- 

 busque piceis. 

 Long. 4| lin., lat. 2| lin. 

 The upper surface is black, slightly polished and covered 

 with very minute punctures, presenting under the lens a shagreen 

 appearance. The elytra, which are slightly striato-punctate, have 

 a large patch of yellow, common to both, extending from near the 

 scutellum almost to the apex. The under surface and legs are 

 of a pitchy hue. 



The S. guUigera of Newman is, perhaps, the nearest to this 

 species of any yet described, but the polished sui^facc and the 

 resemblance to an Adelotopus distinctly mark the former. 



15. — SiLPnOMORPHA QUADRIMACULATA. 



Nigra nitida, thoracis lateribus flavis, elytrorum lateribus macu- 



lisque quatuor flavis, corpore subtus pedibusque piceis. 

 Long. 2| lin., lat. Ij lin. 



This species somewhat resembles the S. hijdroporoides of 

 Westwood. The upper surface is of a brilliant shining black 

 and perfectly smooth. The thorax and elytra have their lateral 

 margins of a reddish yellow, the latter have also four large 

 yellow spots, one near the base of each elytron, the other at the 

 apex. The under surface of the body and the legs are of a pitchy 

 hue. 



16. — Adelotopus apicalis. 



Niger nitidus Isevis, elytris apice rufis, corpore subtus piceo. 

 Long. 3 lin., lat. 1| Kn. 



The upper surface is smooth, black, and sliining, with the 

 apex of the elytra reddish. The under surface is of a pitchy red. 

 This species is broader and less oblong than the A. hceviorrhoidalis 

 of Erichson. 



17. — Adelotopus bimaculatds. 

 Niger nitidus Isevis, elytris maculis duabus sanguincis, abdo- 



mine rufo. 

 Long. 2| lin., lat. 1 lin.
