PKOCULEJUS. 5 



3. Proculejus truquii. 



Proculejus truquii, Kaup, Harold's Col. Hefte, iv. p. 16; id. Monogr. der Passal. p. 62 '. 

 Hah. Mexico 1 (coll. Mniszech). 



4. Proculejus sartorii. 



Proculejus sartorii, Kaup ; Harold's Col. Hefte, iv. p. 17; id. Monogr. der Passal. p. 64 \ 

 Sab. Mexico, Mirador 1 (Dr. Sartorius), Oaxaca (var. 1, Salle). 



A specimen in the Salle collection agrees well with Kaup's description, especially in 

 the flattened surface of the thorax and elytra and the bidentate apex of the mandibles. 

 It differs, however, in the much less extent of the punctulate and hairy lateral interstices 

 of the elytra, the basal portion of the tenth interstice only being so sculptured and 

 clothed. Kaup describes P. sartorii as having the second, third, and fourth marginal 

 (i. e. eighth, ninth, and tenth from the suture) interstices punctulate throughout. 



5. Proculejus pubicostis. (Tab. I. figg. 4, 4ar.) 



Breviter oblongus ; verticis cornu elongate* antice libero et paulluluin elevato, apud basin utrinque tuberculo 

 subrotundato ; carinis frontalibus vix acutis divaricatis usque clypei tuberculum lateralem extensis ibique 

 tuberculatis ; clypeo acute marginato, fronte lsevissima ; tborace sicut in P. brevi, sulculis marginalibus 

 passim angustis, punctatis, foveaque laterali punctulato-pubescenti ; elytris relative quam in hac specie 

 brevioribus, sed antice medio paullo minus prominentibus, sulcatis, sulcis subtilius punctulatis ; inter- 

 stitiis l°-6 m latis, planis, 7° angustiori, glabro, 8°-10 m punctulato-pubescentibus, 9° angusto subearinato ; 

 tibiis 4 posticis extus absque spinis. 



Long. 28 millim. ; tborax 8, elytra 15 millim. long. 



Eab. Mexico, Orizaba (Salle). One example. 



Named P. mexicanus, Truqui, in the Salle collection, but evidently in error as it does 

 not at all agree with Truqui's description. The antennal club has three moderately 

 long, thin leaflets, as in the other species of Proculejus. 



This species differs from the others of this section in the tubercle of the vertex 

 being prolonged into a long, horizontal, laterally subcompressed horn, and in the frontal 

 carinse being widely divergent and ending in a tubercle very close to a similar clypeal 

 tubercle over the base of the mandibles. As it resembles in all other characters 

 P. brevis, the modification in the armature of the head can scarcely be taken as a generic 

 character. 



§ 2. Elytra entirely glabrous. 



6. Proculejus championi. (Tab. I. figg. 5, 5a.) 



Breviter oblongus, elytris subovatis, convexus, niger politus ; clypeo lato, carinaque antice et postice sulco lsevi 

 marginata • tuberculo verticis parum elevato, compresso-conico, postice late sulcato, apice declivi carinisque 

 frontalibus brevibus divergentibus utrinque in tuberculum validum longe ante clypeum terminatis ; man-
