DRACOTETTIX, Bruner. 

 Dracotettix, Bruner, Proc. U.S. Nat. Mus. xii. p. 49 (1889). 



The present genus inhabits the upper austral region of the South-western United 

 States, where several species are represented, and certainly extends into Northern 

 Mexico. The three known forms may be separated by the subjoined table. 

 B. monstrosus may be considered the type of the genus. 



Synopsis of the Species of Dracotettix. 



A 1 . Median carina of the pronotum very prominent and strongly arched 

 both in front and behind the principal sulcus. Fastigiuni bluntly 

 longitudinally carinate. 

 b l . Anterior lobe of the pronotum strongly arched and deeply trilobed; 

 the transverse groove of the face deeply impressed so as to com- 

 pletely sever the carina? of the frontal costa 1. monstrosus, Bruner. 



U*. Anterior lobe of the pronotum less prominent and less strongly 

 arched, only gently trilobed ; the transverse sulcus of the face 

 not, or but slightly, impressed, not severing the carince of the 



frontal costa 2. calif ornicus, sp. n. 



A 2 . Median carina of the pronotum much less prominent and only gently 

 arched in front of and behind the principal sulcus. Fastigium of 

 the vertex strongly longitudinally carinate [3. plulonius, Bruner.]

Draconotus monstrosus, Bruner, MSS. 



Bab. Noeth America, Los Angeles, California (B. W. Coquillett l ). 



While no specimens of this insect are at hand from Mexican territory, it is not 

 unreasonable to expect it to extend further southward. 



2. Dracotettix caHfornicus, sp. n. 



Similar to D. monstrosus in general appearance, but somewhat smaller and shorter winged. As compared 

 with that species, the median carina of the pronotum is lower and less strongly arched, and the lobes of 

 the anterior portion much smaller ; the transverse groove of the face is shallower, so that the frontal 

 costa is not severed by it and in some cases not even lowered at the point of crossing. The hind tibia) 

 of the present species are without the blood-red colour on the inner face, which is common to both 

 D. monstrosus and D. plutonius. 



Length of body, $ , 36 ; of pronotum 11, of tegmina 9, of hind femora 14 millim.
