latitudine "breviore, ante medium rottindatim ralde angustato, ad apicem vix 
tubulato, tuberculis nitidis glabris convexis dispersis (quorum unus ante medium 
dorsali magis acutus) ; elytris ad basin thorace tertia parte latioribus, convexis 
ad apicem rotundatis, antice grosse striatim punctatis postice striatis, inter- 
stitiis omnibus tuberculis nitidis ornatis postice evanescentibus. Long. °82. 
Tampico, Mr. Haldeman, one specimen. The tubercles of the interstices of 
the elytra are less numerous, and indeed almost wanting towards the apex ; 
the 5th has only three, all of which are in front of the middle. The first to 
third joints of the funiculus of the antennje are equal, the fourth and fifth are 
each a little shorter, and the sixth and seventh are still shorter and thicker. 
Sphenophortts Schonh. 
S. V a 1 i d u s , ater opacus subvelutinus, capite rostroque parce punctato, 
fovea frontali profunda, thorace subtiliter parce punctato, dorso postice subde- 
presso, latitudine parum longiore antice magis angustato, lateribus rotundatis, 
ad apicem subito tubulatim constricto ; elytris tenuiter striatis, striis internis 
ad basin parce punctatis, externis obliteratis, sed punctis majoribus notatis ; 
pygidio grosse punctato- subcarinato ; tarsis articulo 3io latissimo transverso 
subtus spongioso, Imo et 2udo subtus excavatis glabris. Long. -97. 
One specimen brought from Sonora by Mr. Schott. Difiers from the next by 
the larger size, the sudden constriction of the apex of the thorax, which is 
less gradually narrowed in front, aud by the subcarinate pygidium. The 
rostrum is longer than the thorax, cylindrical, and bent especially near the 
extremity. 
S. procerus, ater opacus subvolutinus, capite rostroque parce punctato, 
fovea frontali profunda, thorace dorso postice subdeplanato, latitudine paulo 
longiore, antice sensim angustato, lateribus rotundatis ad apicem subtubu- 
lato, ad parum constricto ; elytris omnino sicnt in S. v a 1 i d o : pygidio grosse 
punctato haud carinato ; tarsis sicut in priore. Long. '65 — -82. 
San Diego, California ; under decaying Opuntiae. The beak of the male is a 
little shorter than that of the female ; in the latter, it is as long as the thorax, 
cylindrical and regularly curved. 
S. pictus, elongato-ovalis, supra niger nitidus, capite fascia postocular'; 
pallida, thorace latitudine sesqui longiore, antrorsum sensim angulato, ad 
apicem tubulato, vittis dorsalibus duabus punctatis albidis postice vage 
impressis, lateribus parce punctatis late albidis, margine plus minusve nigro ; 
elytris a humeris postice attenuatis, striis internis profundis haud punctatis, 
externis e punctis compositis, interstitiis planis vix parce punctulatis, 2ndo 
albido uniseriatim punctulato, 4to et 6to ad basin vittaque lata submarginali 
antice abbreviata albidis ; subtus albidus, medio niger, pedibus variegatis, 
tarsis subtus lateribus spongiosis, articulo 3io dilatato ; rostro cylindrico 
thorace parum breviore. Long. -7. 
One specimen ; Vallecitas, San Diego County, California. The black portions 
on the under surface are : a large metasternal spot, and another abdominal, 
the latter is narrowed on the first segment, so that it becomes of the form of 
the abdomen of an ant. The coxse are black with a pale margin, the femora 
are pale, with an elongate spot each side not reaching the tip : the tibiae are 
black, with the outer edge pale. This species must be placed in Schonherr's 
second division near S. discolor, Mann., which by error has been described 
as having the third tarsal joint spongy beneath ; it is so only at the sides, and 
the middle is entirely glabrous. In the present species the terminal internal 
tooth of the anterior tibiae is long and oblique, and immediately above it is a 
smaller tooth. 
S. ochreus, elongato-ovalis, pallide fusco-ochreus, rostro cylindrico, 
antice nigro, vertice nigro, fronte foveata, thorace latitudine longiore, antrorsum 
sensim parum angustato, ad apicem tubulato-constricto, parce punctato, dorso 
subbisulcato, in fundo parcius grosse punctato, linea media dorsali, altera
