108 LONGICORNIA. 
The numerous examples sent home by Champion differ constantly from equally 
numerous examples of A. binotatus, taken by Belt, in the relatively shorter and more 
ovate elytra. There is also a minor and less reliable difference in the mode of emargi- 
nation of the apex of the elytra, the outer angle of which in A. binotatus is always | 
more produced than the sutural, whilst in A. subellipticus the two angles are equal. 
The antennal joints, from the fifth, are whitish at the base, and there is a narrow 
whitish vitta on’ the lower flanks of the prothorax, in both species. The form of the 
pro- and mesosterna offers little difference. | 
8. Adetus antennatus. 
Tautoclines antennata, Thomson, Physis, ii. p. 155°. 
Hab. Mexico 1, Cordova (Sallé, Boucard). 
Differs from A. binotatus by the broader form and darker tawny ochraceous colour 
of the vittee on the elytra. The antenne are also perceptibly shorter. 
9. Adetus leucostigma. 
A, binotato affinis, sed paulo minor et angustior, thorace fulvo trivittato, elytrisque macula postmediana clare 
alba. Elongatus, angustus, fuscus, tomento ochraceo-fusco vestitus; thorace grosse partim confluenter 
punctato, vitta lata laterali alteraque angustiore dorsali ochraceis; elytris medio parallelis, apice ad suturam 
conjunctim emarginatis, supra punctis oblongis seriatim ordinatis, fasciculis minutis maculaque utrinque 
transversa postmediana albis, lincola obliqua antica alteraque prope apicem ochraceis vel albis; antennis 
haud incrassatis, versus apicem nigris, articulis basi griseis ; mesosterno arcuato. 
Long. 3-47 lin. 
Hab. Mexico (Sallé); Guaremata, Chinantla, 4100 feet (Salvin), Zapote, San Gerd- 
nimo (Champion); British Honpuras, Belize (Blancaneaux). 
It is difficult by description to make clear the differences between this species and 
A. binotatus, the colour and markings being very similar. ‘The two, however, are very 
distinct. A. leucostigma is a decidedly narrower insect, and is covered with coarser 
pubescence; the elytra are more gradually attenuated posteriorly, and the seriated 
punctures are more oblong. 
10. Adetus denticauda. 
A. binotato similis, sed differt elytris apice utrinque valde bidentatis etc. Elongatus, subcylindricus, subseneo- 
fuscus nitidus, vitta laterali thoracis utrinque versus medium elytrorum continuata, macula transversa post 
medium alteraque angustiore prope apicem ochraceo-tomentosis ; capite thoraceque grosse punctatis (hoc 
linea dorsali ochracea); elytris parallelis, a medio usque ad apicem gradatim angustatis, apud apicem subito 
declivibus ibique grossissime punctatis suturaque elevata, apice ipso utrinque bidentato ; antennis apicem 
versus paullo incrassatis ; mesosterno inter coxas haud elevato. 
Long. 34-44 lin. 
Hab. Guatemaa, Sabo, Vera Paz (Champion). 
Differs from A. binotatus and all the preceding allied species by the ochraceous lateral 
vitte of the thorax being continued to the humeral region of the elytra, whence they
