21. AuLAcoCHiLus AGABOiDEs, var. ? FTJRCiFERUS. (Plate 

 XVIII. fig. 11.) 



A. agaboidi similis at paullo major, macula basali cum lunula 

 suhapicali per vittam discoidalem conjuncta. 



Long. 9| millim. 



Hab. Philippine Islands, N.W. Luzon {Semper). 



If this is only a variety of the species already described as 

 A. agahoides, it would still be an advantage that it should have a 

 separate designation ; but I think it will very probably prove to be 

 a constant form. The basal yellow mark is of the same shape ; but 

 its second and third teeth are lost in the conspicuous vitta which 

 unites it with the posterior lunule. This mark has its points so 

 strongly recurved as to form three quarters of a ring. A single 

 specimen is in my collection ; and I have not seen it elsewhere. 



22. AuLACocHiLus EPiscAPHOiDES. (Plate XVIII. fig. 12.) 



Oblongo-ovatus, parum nitidus, nigro-subcyaneus ; capite profunde , 

 thorace obsoletius sed crebre punctata, alutaceis, hoc antice 

 angustato lateribus paululum rejlexis ; elytris tenuiter punctato- 

 striatis, interstitiis obsolete crebre punctatis, macula magna baseos, 

 punctum nigrum includente, fasciaque lunulata nee suturam nee 

 marginem attingente sanguineis. 

 Long. 9 millim. 

 Hab. Andaman Isles. 



Less convex than usual for the species in the genus, nor so much 

 attenuated in front and behind as is generally the case. The general 

 form is that of A. sericeus, Bedel, to which section of the genus the 

 present species belongs. It may be recognized from any described 

 species by the black round spot, which is surrounded by the red 

 basal patch. This patch has three short branches externally, one 

 towards the base and one towards the outer margin, between which 

 is the callus ; there is a third short branch at the outer posterior 

 angle. The posterior lunule has rather the appearance of a double 

 united spot, both sides being indented. 



23. PSELAPHACUS MYSTICUS. 



Niger, nitidus, thorace seriebus duabus punctorumj elytris fortiter 



punctato-strialis, macula basali bifida, fasciis tribus undulatis, 

 posteriore ramum ad apicem emittente et cum fascia secunda 

 conjuncta lineaque submarginali falvis ; tibiis anterioribus cur- 

 vatis, ad apicem ampliatis, intus crenulatis. 

 Long. 14-17 millim. 

 Hab. Peru, Chancomayo. ^ . 



Allied to P. curvipes, but very much more shining, and differing 

 in pattern, having three transverse fasciae besides the basal bidentate 

 mark, of which the two posterior are joined near the suture by a 

 straight baud. In some varieties of P. curvipes, viz. in my examples 

 of the variety named gracilis, the third fascia has a stripe uniting 

 it with the apex ; but this stripe (which is present in P. mysticus)
