250 SUPPLEMENT. 
The close punctuation of the thorax in the male is similar in all three species; but in 
the female H. grisescens differs from the others in the sculpture not consisting of large 
punctures, but of very fine, short, curved elevated lines, ¢. ¢. it forms a reticulation with 
the meshes almost everywhere broken, the depressed portions being black and opaque. 
The truncature of the elytra is sharper than in H. inermis, with both angles distinct, 
but unarmed. 
10. Hypermallus subseriatus. 
H. inermi affinis. Subcylindricus, supra fulvo- subtus griseo-tomentosus; thorace (2) cylindrico-ovato sat; 
crebre ocellato-punctato linea tenui dorsali integra levi; elytris subseriatim punctatis, fere equaliter 
fulvo-tomentosis, erecte pubescentibus, apice oblique truncatis angulo suturali obtusissimo; antenne 
articulis 3°-6™ apice intus spinosis, spina art. 3' longiori. 
Long. 63-8 lin. 9. 
Hab. Panama, San Lorenzo (Champion). 
11. Hypermallus eximius. (Tab. XVII. fig. 19.) 
Nigro-fuscus ; elytris abdomineque castaneo-rufis, antennis pedibusque pallidius rufis, pilis discretis incum- 
bentibus albis vestitus, thorace maculis octo, elytris fasciis macularibus duabus (1* mediana, 2* ante 
apicem) niveo-tomentosis; thorace subcylindrico, dorso confertim alveolato, spatio parvo discoidali levi ; 
elytris versus apicem angustatis, apice breviter oblique subsinuato-truncatis, passim confertim punctulatis ; 
corpore subtus vitta macularia vel interrupta cinereo-tomentosa a collo usque prope ventris apicem extensa. 
Long. 6 lin. ¢? 
Hab. Mexico, Oaxaca (Sallé). 
One example. The thorax is spotted almost the same as in the Australian 
Strongylurus thoracicus and S. cretifer. 
12. Hypermallus lanuginosus. (Tab. XVIII. fig. 4.) 
H. villoso (Fabr.) affinis; minus elongatus thoracisque lateribus fere parallelis etc. Linearis, testaceo- 
ferrugineus pube subfloccosa fulvo-ochracea dense vestitus, corpore subtus pedibusque obscure fuscis ; 
fronte declivi, planata, oculis supra valde distantibus; thorace cylindrico, (9?) sparsim grosse punctato, 
medio levi; elytris apice late truncatis, angulo suturali recto, exteriori longe spinoso, sat crebre punctatis, 
pube vix maculatim vestitis, pilisque erectis densis brevibus; 9? antennis articulis 3° et 4° solum per- 
spicue spinosis, art. 4° quam 3" vel 5" distincte breviori. 
Long. 5 lin. 9? 
Hab. Guatemata, Cerro Zunil 4000 feet (Champion). 
Three examples, apparently all females, the sculpture of the thorax consisting of 
large scattered punctures, with a dorsal longitudinal smooth space; the dense and 
rather curly incumbent pubescence conceals the punctuation to a great extent. 
13. Hypermallus longissimus. (Tab. XVII. fig. 4.) 
4. villoso (Fabr.) affinis, sed multo major, thorace elongato, anguste cylindrico. Valde elongatus, postice 
(precipue ¢) gradatim angustatus, castaneo-fuscus, pube argenteo-cinerea vestitus (guttulis fuscis inter- 
rupta) setisque perpaucis erectis ; antennis ¢ 9 quam corpus multo brevioribus, articulis 3°-6™ apice intus
