4. Astynomus picticauda. 
Oblongus, angustus, subconvexus, elytris breviter setosis granulis nonnullis asperatis; capite nigro, linea cen- 
trali vittaque infra oculos ochraceis ; thorace parvo, tuberculo laterali conico acuto mox pone medium, dorso 
fusco et nigro-fusco variegato, guttulis dorsalibus alterisque lateralibus confluentibus ochraceis; scutello 
nigro-fusco; elytris apice breviter sinuato-truncatis, angulo exteriore paullo producto, supra inequalibus 
punctatis basi et lineis dorsalibus granulatis—purpureo-fuscis nigro et ochraceo-guttatis, maculaque 
utrinque apicali nigro-fusca intus late ochraceo marginata; antennis utroque sexu quam corpus paullo 
longioribus modice robustis, fere nudis, rufo-piceis, articulis apice nigro-fuscis, basi pallidis ; corpore subtus 
ochraceo, mesosterno latiusculo; pedibus ochraceis, femoribus et tibiis nigro biannulatis; tarsis nigris, 
articulo basali ochraceo. 
do. Abdominis segmento apicali lamina dorsali semicirculariter emarginata, ventrali obtuse minus sinuata.

Long. 43-5 lin. § 9. 
Hab. Guatemata, Cerro Zunil (Champion). 
This prettily marked species accords in the generic characters at present accepted 
neither with Astynomus nor Urographis. In its general form, however, it resembles 
the typical species of the former genus much more closely than any other of this 
perplexing group. If it be thought desirable to separate it generically, the following 
two species will have to be associated with it. 
5. Astynomus nigropunctatus. 
A. picticaude simillimus, differt precipue signaturis elytrorum. Oblongus, angustus, setosus; capite 
thoraceque ut in A. picticauda; elytris griseo- vel purpureo-fuscis nigro et griseo-ochraceo punctatis, 
fascia post medium nigro-fusca, altera dentata paullo ante apicem cinereo-ochracea maculaque apicali 
ejusdem coloris; antennis, pedibus et abdominis structura ut in A. picticauda. 
Long. 32-6 lin. ¢ Q. 
Hab. Mexico, Cordova (Sallé) ; GuaTEMALA, Sinanja, Purula (Champion). 
-The Mexican examples differ from those of Guatemala in the less contrasted colours 
of their markings, the ochraceous hue of their spots and fascize being replaced by ashy 
grey; but the position and shape of the spots are almost identical. I have adopted 
for the species the MS. name given by M. Chevrolat in the Sallé collection. 
6. Astynomus tenebrosus. 
Latius oblongus, convexus, cinerascenti-niger, breviter setosus, elytris fascia lata ante apicem nigra antice 
cinereo-albo marginata liturisque cinereis prope apicem; capite omnino cinereo-nigro; thorace quam 
elytra multo angustiore sed transverso, tuberculo laterali apud medium sito, validissimo, antrorsum paullo 
spectante, dorso tuberoso valde insequali, nigro, macula utrinque cinerea nigro punctata ; elytris latius 
oblongis, dorso ineequalibus aspere granulatis et punctatis tuberibus centro-basalibus elevatis, apice sinuato- 
truncatis, angulis suturali et exteriore equaliter leviter productis ; antennis (2) modice robustis, quam
