" Elongato-ovalis, postice attenuatus. Capita testaoeo ; prothorace testaceo, postice linea transversali 

 nigra ornato ; elytris nigro-fuscis, ad marginem testaceis, permultis lineolis undulatis, ad basin et apicem 

 plus minusve confluentibus, testaceis ornatLs ; subtus fusco-niger, pedibus testaceis, posticis infuscatis. 

 Long. 2| a 3^ m.m." 



\^At p. 3.58, op. cit., this diagnosis is stqjplemented by a description.^ 



1486. Laccophilus piimilio, Lee, Proc. Am. Phil. See, 1878, p. 596. North America. 



" Ovate, pointed behind, not convex, unpunctured, rufo-testaceous, meso and metasternum darker ; elytra 

 piceous, slightly iridescent, regularly narrowed behind, and not obliquely truncate at tip ; abdomen with- 

 out the distant fine oblique lines seen in the other species. Length 1*9 m.m. ; '075 inch." 



" Enterprise, Florida ; one specimen. Very careful examination shows in certain lights traces of two 

 or three lines on the second ventral segment towards the sides, but these are the only evidences of the 

 characteristic ventral sculpture of the other sjjecies." 



1487. Laccophilus quadrisignatus (Lap.), Aub^, Spec. p. 436. Cayenne. 



" Ovalis, apice rotundatus, depressiusculus, rufo-testaceus ; thorace postice in medio leviter iufuscato

 macula minima ad marginem, altera in apice luteo-ornatis. Long. 3|, lat. 2J m.m." 



\_Auhe, 1. c, supplements the above diagnosis with a description.'] 



1488. Laccophilus rivulosus (Klug), Aube, Spec. p. 425. Madagascar. 



" Ovalis, apice vix oblique rotundatus, depressiusculus, testaceus ; cajiite in vertice nigro ; thorace 

 antice et postice nigro-maculato, in medio breviter acute producto ; elytris nigris, maculis irregularibus 

 ad marginem lineolisque plurimis in disco testaceo-ornatis. Long. 5, lat. 3 m.m." 



{This diagnosis, 1. c, is followed by a descriptioyi.] 



This species is probably allied to L. lateralis (No. 148). — D. S. 



1489. Laccophilus stroehmi, Th., Op. Ent. VI, p. 535. Helsingfors. 



" Ovalis, sat convexus, pallide testaceus, antennis palpisque apice nigris ; coleopteris medio dilatatis, 

 subtilissime subrugoso-punctatis, fuscis, basi et lateribus dilutioribus." 



" L. minuto fere major, antennarum palporumque colore, elytris magis convexis, punctura evidentiore, 

 fuscLs maculis pallidis nullis determinatis bene distinctus. Caput pallide testaceum, clypeo ante apicem 

 linea subcurvata impi'essa ; palpis utrisque apice nigris. Anteunse pallide testacese, articulis 5-6 ultimis 

 apice sensim magis nigris, quarto tertio breviore. Prothorax basi coleopteris fere angustior, latitudine 

 sua triplo brevior, apice truncatus, angulis auticis sat magnis productis ; lateribus oblique antrorsum 

 angustatis ; basi medio late subproductus, testaceus, Isevis. Elytra prothorace saltem quath-uplo longiora, 

 lateribus paullo ante medium subdilatata, sat convexa, fusca, basi et limbo laterali pallicUore; punctis,
