Description —Corpus elliptico-ovolum, supra aut planiusculum, aut paraum 
convexum, alatum, plerumque mediae magnitudinis. Antennae thoracis me¬ 
dium pertingentes, prope basim rostri insertae, validusculae, fractae, 
articulatae, scapo elongato thoracem apice attingente, sub-clavato; funiculo 6- 
articulato; articulis, 1, 2 oblongis, turbinato, obemicis, 3-6 in pleresque sub- 
rotundatis in caeteris sub-turbinatis, exterioribus successive parum crassiori- 
bus, omnibus distantibus; clava breviter ovata, compressa, cuneiformis bi- 
articulata; articulo 1° corneo, apice truncato, 2° spongroso, apice acetoto, aut 
truncato, aut sub-rotundato. Rostrum fere longitudine throacis, ante inser- 
tionem antennarum crassius dein sub-tenne, arcuatum, deflexum. Ocli lale- 
rales, infra caput fere connexi, oblongi depressi. Thorax lalitudine baseos 
longior in plerisque bisinuatus, in allis rotundato productus, lateribus in ple¬ 
rumque basi sub-rectis, dein versus apicem porun rotundatis; anterius angus- 
tior, in nonnullis magnis aequaliter rotundatus, anticc subito angustior, sem¬ 
per longe intra apicem profunde, coaratus collun quasi annuliforme formans 
convexus. Scutellum triangulare. Elytra antice thoracis basi parum latiora 
et ilia fere sesqui-longiora basi partim singulatim, sub-rotundata, partim con- 
junctium introsum rotundata—emarginata pcne basim oblique ampliata dein 
posterius attenuata apice obtutus rotundata, aut sub-trunctata, abdomine 
breviora, supra in plerisque planiuscula in paucis nonnihil convexa. Pygid- 
ium sub-triangulare, deflexum. Pedes mediocres, longitudine sub-aequales 
validi; femoribus clavatis, saepissiare muticus raro sub-tusfixo, valido ter- 
minatis tarsi, elongatis, articula penultima, aut majusculo, subtus spongioso, 
out paulo minori subtus haud spongioso, unguiculari elongato clavato bi- 
inguiculata. 
Typhus Sphenophorus abhreviatus. 
(Patria T'otus orbis; praesertim vero regiones calidae.) 
Obsery —In numeroso hoc genere occurunt quedem species nonnulae, omni¬ 
bus supra indicatis characteribus non exacte convenientes; dum vero notis 
generis maxime essentialibus correspondent, illas separare minus necesse 
censui. Inveniuntus elim aliae quarum forma corporis paulo convexior et 
tarsi diversimoda construed pro quibus, ut interim saltern stirpem peculiaren 
assignavi. 
Riley (1881) gives the following as the distinguishing characters of 
the genus: 
“The distinguishing generic characters of Sphenophorus may be 
given briefly as follows: Side pieces of metasternum rather narrow; 
epimera of mesostemum externally truncate (not acute) ; front coxae 
narrowly separated by the prosternum; third joint of the hind tarsi 
either glabrous or only pubescent on the sides. A peculiar external 
appearance will render the genus at once recognizable to the experi¬ 
enced eye, while the numerous species are very difficult to distinguish. 
The form of the tibia and tarsi and the vestiture of the latter have 
furnished excellent characters to divide the genus into natural groups. 
That to which our species (robustus) belongs is characterized as fol¬ 
lows 
Blatchley and Leng (1916) decribe the genus Sphenophorus as fol¬ 
lows : “Rather large, robust, usually elliptic-ovate species, having the
