DIPLOTAXIS. 165 



Eab. Mexico, Ciudad in Durango (Forrer), Toluca (Salle). 



Three examples. The one from the Salle collection is labelled D. simplex, Blanch., 

 but is certainly different specifically from other three examples in the same collection 

 bearing that name, and agreeing less with Blanchard's description, such as it is. 



26. Diplotaxis ? 



Eab. Mexico, Jalapa (Edge). 



A single example of a species indeterminable. 



27. Diplotaxis magna. 



Oblonga, robusta, nigra, glabra, subnitida, palpis antennisque rufo-testaceis ; capite lato obtuso, dense subgrosse 

 partim confruenter rotundato-punctato, clypeo fere rotundato, margine antieo leviter sinuato et reflexo, 

 fronte medio depressa ; thorace valde transverso, densissime conflu enter punctato, medio dilatato, postice 

 sinuato angulisque posticis exstantibus acutis, antice subrecto, angulis anticis acutis ; elytris costis valde 

 distinctis haud elevatis, parum punctulatis, interstitiis latis confuse multipunctatis ; pygidio grossissime 

 setifero-punctato ; corpore subtus sparsim subtilius punctato ; unguibus longe infra apicem robuste dentatis. 

 Labrum arcuatim late excavatum. 



Long. 14-15 millim. 



Eab. Mexico, Ciudad in Durango 8100 feet (Forrer, Edge). Four examples. 



28. Diplotaxis boops. 



Magna, oblonga, nigra, nitida, glabra, tarsis, antennis palpisque rufo-testaceis ; capite magno, rotundato, sparsim 

 punctato ; clypeo brevi subrotundato, apice obtusissime truncato, margine parum reflexo ; tborace valde 

 transverso, medio baud dilatato, lateribus leviter rotundatis, antice et postice recte paullo angustato, angulis 

 omnibus subrectis, supra subtiliter disperse punctato; elytris costis valde distinctis baud elevatis, parum 

 punctulatis, interstitiis latis confuse multipunctatis ; pygidio grossissime setifero-punctato ; corpore subtus 

 sparsim subtilius pilifero-punctato ; unguibus longe infra apicem robuste dentatis. Labrum arcuatim 

 late excavatum. 



Long. 14 millim. 



Eab. Mexico, Pinos Altos in Chihuahua (Buchan-Eepburn), Ciudad in Durango 

 (Edge). 



Two examples. Evidently closely allied to J), magna, notwithstanding the very 

 different outline and sculpture of the thorax. 



29. Diplotaxis ? 



Eab. Mexico, Northern Sonora (Morrison). 



A testaceous-red species, with remarkably explanated hind angles of the thorax, 

 the angles subacute at the apex. It is found also in Arizona, and has probably been 

 described by American entomologists. 



IV. Clypeus brevis, obtusus, margine antieo valde sinuato. 



30. Diplotaxis flavisetis. (Tab. IX. fig. 26.) 



Oblonga, postice dilatata, fulvo-castanea, undique setis recumbentibus fiavis obsita ; clypeo lato et brevi, lateribus
