LONGICORNIA. 355 
DILIOLOPHUS (to precede the group Pogonocherini, p. 118). 
Quoad characteres systematicos ad “ Groupe Apodasyides” (Lacord.) pertinet, sed corpore haud piloso. Corpus 
sat breviter oblongo-cylindricum, subtiliter tomentosum. Caput exsertum, inter oculos latum, vix concavum, 
fronte breviter quadrata, planata; oculi subtiliter granulati, lobo inferiore subquadrato. Antenne corpore 
(¢) vix longiores, robuste filiformes, subtus sparsim ciliate, scapo oblongo-conico, articulis 3°-4™ medio- 
criter elongatis, 5°-11™ brevioribus, 11° acuto. Thorax cylindricus, tuberculo (vel spina) mediano laterali, 
acuto. Elytra ante apicem declivia, apice rotundata, tuberculo utrinque centro-basali validissimo, conico, 
nitido. Pedes sat elongati, brevissime setosi; tibie intermedia elongate, simplices; tarsi lati, robusti, 
unguibus divaricatis. Prosternum arcuatum (capite valde distanti), acetabulis extus angulatis; meso- 
sternum declive, acetabulis apertis. 
The species on which this genus is founded has the ordinary appearance of a small 
Monohammus; but its structural characters are the same as those of the group 
“ Apodasyides” of Lacordaire. It has probably a real affinity with Hupogonius and its 
allies, though destitute of the long hairs which clothe the body and antenne of nearly 
all the members of the group. 
1. Diliolophus vexator, (Tab. XXII. fig. 17.) 
Tomento subtili cinereo-fusco vestitus, subnitidus ; elytris pone medium lineolis numerosis transversis contiguis 
fasciam latam fere efficientibus, nigris nudis; antennis rufescenti-fuscis, articulo 4° basi pallidiori; capite 
et thorace sparsim punctatis, hoc disco inequaliter subtuberculato; elytris grossius, postice striatis, punc- 
tatis, tuberculo centro-basali nigro nitido.

ESTOLA (p. 118). 
Dr. Horn has remarked, with regard to the Californian EHstola (2) sordida, that it 
differs from Lacordaire’s definition of Estola, and probably does not belong to that 
genus. This is quite true; it forms with E. perforata and the three species presently 
to be described, viz. EL. fulvitarsis, E. prolongata, and E. leucosticta, a distinct group 
differing from Lacordaire’s Estola in the broad and short lower lobe of the eyes and 
gradually sloping mesosternum; the granulation of the eyes and form of the scape offer 
no essential difference. But the form of the lower lobe of the eyes and of the meso- 
sternum is not constant, but varies gradually in the score or so of South-American Lstole 
which I have examined. Still there remains sufficient difference to distinguish the FE. 
sordida group. It remains to be seen to which group the original Hstola of Fairmaire 
is to be referred.
