head end after fixing it to some object if a suitable one is available, 

 and then makes the other extremity the exit end, a reversal precisely 

 the same as occurs in Psychidce and Coleophorce. It closes this end 

 by a portion of silk that protrudes beyond the valves as a white line, 

 and admits of being easily ruptured from within. 



In case-bearing Adelidce generally the two ends of the case are 

 usually so much alike that the question of whether the larva so re- 

 verses itself for pupation must be diilicult to investigate ; I am not 

 aware of any answer having been given to it. — T. A. C.

 BY VROF. O. M. EEUTEE. 



The two insects described were found by Mr. G. C. Champion 

 during his recent expedition to Central Spain, and the specific names 

 adopted have been suggested by him. 



1. PlEZOSTETHUS TERKICOLA, Sp. 11. 



Niger, laavis, niteus ; antennis totis femoribusque nigro-piceis, 

 tibiis tarsisque sat obscure testaceis, tibiis posticis interdumquc etiain 

 anterioribus basi saepe picescentibus ; hemielytris piceis, clavo, em- 

 bolio cuneoque nigris, forma? bracbyptera? basin segmenti .tertii abdo- 

 minis attingentibus, dimidio basali sutura? clavi discrete, cuneo corio 

 circiter triplo breviore, distincte leviter declivi, membrana angustis- 

 sima lineari ; tibiis ppstice tenuiter spinulosis, tenuissime et brevis- 

 sime parce pubescentibus, pilis exsertis destitutis ; riina orificiorum 

 metastethii in angulum leviter obtusum curvata, mox ante marginem 

 basalem pleurae abbrcviata. Long., If — \ mm. 



This species was found at AJbarracin under stones on a high 

 ridge clothed with pines, in company with Galeatus, Acalypta, Ag- 

 ramma, &c. 



P. oblujuo, Costa, valde afiinis, differt tamen hemielytris piceis 

 nee albovariegatis tibiisque pilis exsertis destitutis ; P. cursitante, 

 Fall., minor, obscurior, magis nitens, antennis obscurioribus, arti- 

 culo secundo breviore (spatio intcroculari verticis distincte breviore), 

 ultimis nigro-piceis, hemielytris forma? brachyptera? paullo longioribns, 

 obscurioribus, sub-hevibus (omnium tenuissime parcius punctulatis), 

 sutura clavi saltern dimidio basali discreta, cuneo brevi sed discreto et 

 leviter declivi divergens.
