110 THE entomologist's RECORD. 



coleopterists have taken it, or more than a sino^le specimen at a time. 

 As I have pointed out, the larva and pupa have been described, but I 

 here figure them for the first time (pi. ix., figs. 4-5). This species has 

 nothing to do with ants, its occurrence with them having been, of 

 course, only accidental. 



The drawings are by Mr. Hereward Dollman, Mr. Horace Knight 

 and Mons. Engel Terzi.

4. Steropleurus siculus, Fieher { = idioii}c'naei, Luc). 



Resembles the preceding, but smaller, the ovipositor less strongly 



curved, the sulci of pronotam not black, the anterior tibise occasionally 



spined above; subgenital lamina ? with obtuse lobes. Length of 



body, 22mm. ^ , 2omm. $ ; of pronotum, 7mm. <? and ? ; of posterior 



femora, 15mm. J , 17mm. $ ; of ovipositor, IGmm.-lSmm. ? . 



An Italian species, taken at Cosenza, and in Sicily at Palermo, 

 Messina, and Siracuse. 



5. Steropleurus ortegai, Pantel. 



Resembles N. stall in colour and appearance ; the ovipositor is 

 remarkably short for this genus ; the shape of the cerci distinguish 

 the male, and also the supra-anal plate. Length of body, 28mm. J , 

 32mm. 5 ; of pronotum, 7mm. ^ , 8mm. 2 ; of posterior femora, 

 14mm. (^ , 15mm. ? ; of ovipositor, 15mm. $ . 



The colour of the adult insect, which inhabits Berberis nih/aris and 

 Juniper as communis, both shrubs with blackish-violet fruit, is blackish- 

 violet. It was discovered in small numbers in the highest parts 

 of the Sierra de Cuenca, by Father Pantel ; the localities quoted are 

 Yalsalobre and Las Majadas. 



6. Steropleurus asturiensis, Bolivar. 



Smaller than S. stall, from which it differs also in the shorter 

 ovipositor and supra-anal plate; from S. catalaunlca and S'. orteijal it 

 differs in having no black spinule at the apex of the cerci of the male ; 

 general colour green. Length of body, 19mm. J , 20mm. $ ; of 

 pronotum, 6mm. <? , 6-5mm. J ; of posterior femora, 13mm. J , 

 15mm. $ ; of ovipositor, 13mm. 5 .
