Hah. Mexico (Salle, ex coll. Sturm), Cuernavaca (Edge). 



A species remarkable for its long shovel-shaped clypeus, the anterior recurved margin 

 of which projects far beyond the labrum. The mandibles are not visible and the tarsi 

 are robust-filiform, characters which show that the insect is closely allied to Bhizo- 

 trogus. It bears the unexpressive name Ancylonycha pallida, Sturm (MS.), in the 

 Salle collection. 



14. Phytalus hogei. (Tab. X. fig. 12, 6 .) 



Oblongus, glaber, nitidus, castaneus, subtus fulvo-testaceus ; capite discrete baud grosse punetato, clypeo lateribus 

 parum rotundatis, margine reflexo, antice sinuato ; tborace ante medium dilatatus, deinde usque ad basin 

 recto (lateribus parallelis), discrete punctulato ; elytris mediocriter ruguloso-punctulatis, costis paullo 

 distinctis ; pectore flavo-villoso. 



6 . Pygidium fere planum, disperse sat grosse punctatum, glabrum. Yenter medio vix depressus, politus, 

 segmento 5° simpKci, 6° medio transversim haud profunde impresso vel sulcato fere lBevi. Calcaria 

 postica gracilia. Ungues dente inferiore cum apicali parallelo haud latiore, acuto, multo breviore. 

 Antenuarum clava valde elongata, cseteris articulis conjunctis multo longior; articulis 4°-7 m mtus 

 paullulum productis, 6° et 7° brevioribus et latioribus. 



$ . Pygidium basi convexum, bicallosum, apice planum, glabrum, parum punctulatum.

Eab. Mexico, Toluca (Edge). 



Nearly a score of examples. This species, like others of this section, has the facies 

 of a Bhizotrogus.

 Calcaria postica gracilima, acuta. Ungues basi obtuse dentati, apice anguste fissi, dente inferiore vix 

 latiore multo breviore. Antenuarum clava valde elongata, pentapbylla, articuli T lamina paullo, 6" multo, 

 abbreviata, articulo 5° intus sat longe, 4° brevius acute productis.
