“JT, minuto cui affinis minor. Corpus subtus testaceum, immaculatum. Caput et thorax rufo-testacea, 
immaculata nitida, antenne testacez. Pedes testacei posticorum tibiis tarsorumque articulis apice

* Hlongato-ovalis, postice attenuatus. Capite testaceo ; prothorace testaceo, postice linea transversali 
nigra ornato ; elytris nigro-fuscis, ad marginem testaceis, permultis lineolis undulatis, ad basin et apicem 
plus minusve confluentibus, testaceis ornatis ; subtus fusco-niger, pedibus testaceis, posticis infuscatis.

1486. Laccophilus pumilio, Lec., Proc. Am. Phil. Soc., 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 species.” 
1487. Laccophilus quadrisignatus (Lap.), Aubé, Spec. p. 486. Cayenne. 
“‘Ovalis, apice rotundatus, depressiusculus, rufo-testaceus ; thorace postice in medio leviter infuscato

macula minima ad marginem, altera in apice luteo-ornatis. Long. 32, lat. 24 m.m.” 
[Aubé, 1. ¢., supplements the above diagnosis with aw description. | 
1488. Laccophilus rivulosus (Klug), Aubé, Spec. p. 425. Madagascar. 
“‘Ovalis, apice vix oblique rotundatus, depressiusculus, testaceus ; capite 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.”

1489. Laccophilus streehmi, 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.” 
“LL, minuto fere major, antennarum palporumque colore, elytris magis convexis, punctura evidentiore, 
fuscis maculis pallidis nullis determinatis bene distinctus. Caput pallide testaceum, clypeo ante apicem 
linea subcurvata impressa ; palpis utrisque apice nigris. Antenne pallide testacee, articulis 5-6 ultimis 
apice sensim magis nigris, quarto tertio breviore. Prothorax basi coleopteris fere angustior, latitudine 
sua triplo brevior, apice truncatus, angulis anticis sat magnis productis; lateribus oblique antrorsum 
angustatis ; basi medio late subproductus, testaceus, levis. Hlytra prothorace saltem quadruplo longiora, 
lateribus paullo ante medium subdilatata, sat convexa, fusca, basi et limbo laterali pallidiore; punctis,
