ANISOPODUS.—PATTALINUS. 165 
latter forms near the black outer border and in the middle of the black apical area 
various transverse or oblique and zigzag lines; an obscure dark brown patch is also 
seen on each side of the suture behind the scutellum. It is the only species known in 
which the angles of the apical truncature of the elytra are not spinose or produced, 
and in this respect does not differ from the typical Lepturges. 
PATTALINUS. 
Anisopodo et Lepturgi proxime affinis, at differt antennarum articulo sexto vel quinto apice subtus dente armato. 
Corpus elongato-oblongum, lave, depressum. Caput antice breve, fronte infra angustata; oculi magni. 
Antenne (¢) corpore plusquam duplo longiores, subnude, articulo tertio quam scapus vel articuli 
sequentes haud longiore, sexto vel quinto apice subtus denticulo conspicuo parvo armato. Thorax 
antice modice subrecte angustatus, spina laterali, lata, acuta, sat ante basin sita, deinde lateribus sinuatim 
modice angustatis. Elytra subdepressa, epipleuris verticalibus sed haud carinatis, apice sinuato-truncata. 
Pro- et mesosternum angustissima. Pedes sat elongati; femora postica elytris vix breviora, paullulum 
incrassata ; tarsi postici articulo primo quam sequentes duo conjuncti longiore. 
The minute dentiform projection existing, in one species at the apex of the sixth, and in 
another of the fifth, antennal joint is of similar nature to that of the sixth joint in the 
males of Lagochirus. The same curious structure distinguishes also the North-American 
genus Canopeus (Horn) and the South-American Amniscus ; but in the last-named it is 
on the third instead of the sixth joint. Pattalinus differs from all three by the spined 
thorax and smooth surface of the body. There is so close an affinity in all other respects 
between the two species described below, that I am inclined to disregard the curious 
difference in the situation of the armature of the antenne, and include them in one 
genus. 
1. Pattalinus charis. 
Canescens, abdomine, pedibus et antennis flavo-testaceis, harum articulis (a 3°) apice tibiisque apice nigris ; 
thorace vittis duabus dorsalibus, elytris vittula curvata ccntro-basali, altera laterali sub humeris, fasciis 
duabus postmedianis tenuibus valde flexuosis nigris, apice profunde sinuato-truncatis, utrinque bidentatis, 
dente exteriore longiore.

2. Pattalinus cultus. 
Griseo-sericeus, capite, antennis et pedibus rufescenti-fuscis; thorace vittis duabus dorsalibus alterisque 
lateralibus, elytris lineolis elongatis plurimis basalibus, epipleuris basi, vittula apicali fasciaque valde 
dentata longe post medium atro-fuscis ; thorace ab spine apice usque ad angulum anteriorem sat angustato, 
pone spinam sinuatim modice constricto : elytris apice sinuato-truncatis, angulo exteriore modice, suturali 
. haud producto ; femoribus posticis magis incrassatis, tarsis paullo brevioribus.
