quetral, blunt, especially in female; niesosternal lobes subquadrate, rounded at inner 

 apical margin, separated by their own width ( 9 ) or by less than that {$ ); meta- 

 sternal lobes subattingent ( ^ ) or distinctly separated ( 9 )• Tegmina slender lanceo- 

 late, lateral, with prominent longitudinal veins, reaching the third abdominal seg- 

 ment. Fore and middle legs rather short ; hind legs long and rather slender, the 

 hind femora tapering very regularly, not very strongly compressed, with smooth 

 superior carina and bluntly acuminate genicular lobes, angulate mesially beneath ; 

 hind tibire pilose, with 8-9 spines on either margin, the apical spine wanting on the 

 outer side, the margins rounded. Abdomen compressed, elongate, tapering, multi- 

 carinate. 



Clematodes larrese (Cod-, sp.), sp. nov. 



Gray of the exact tint of the stems of Larrea on which it was found, the gray 

 everywhere made up of black and white marbling in little long oval patches largely 

 lost in desiccation, pallid beneath ; eyes with the same marbling in life ; after death 

 the whole becomes fuscous, irregularly and feelily mottled with testaceous, all the 

 elevated parts black. Fastigium of vertex carinate in front, the vertex also with a 

 median carina which extends forward nearly to the front border of the eyes, and is 

 bordered by a smooth space, and this by a heavily punctate band posterior to the 

 hinder extremity of the lateral carinate margins of the fastigium, which are just 

 above the middle of the eyes. Pronotum rugose by longitudinal ruga: in which a 

 median carina is easily distinguishable and a number of broken subordinate carina;, 

 both on disk and lateral lobes. Tegmina extending to just beyond the base of the 

 hind legs. Hind femora extending posteriorly a little beyond tip of abdomen, 

 mottled and with obscure fuscous fasciation, the lighter colors principally above, the 

 inferior sulcus bright crimsQU ( 9 )» or orange ( ^ ), the latter fading to luteous after 

 death.

'* I was yesterday afternoon," writes Mr. Cockerell, "on my back 

 under a Larrea bush, watching the great red-eyed bees visit the flow- 

 ers. As I looked up it gradually dawned upon me that there was 

 something Orthopterous on one of the Larrea stems, and taking hold 

 of it, it proved to be a (? and 9 in copulation of a species of Acridiinte 

 exactly mimicking in color the stems of the Larrea. This was par- 

 ticularly interesting, as we have already Bootettix argeiitatiis con- 

 fined to the Larrea (Bruner gives the food plant wrong) and exactly 

 resembling the foliage ; and now here is a species like the stems." 



I have introduced into my description the notes on the color of the 

 living insect given me by Mr. Cockerell in a brief description of the 

 species, and have adopted his specific name.
