Habitat Gomeram, prope " Hermigua " a Dom. Crotch repertus. 



This most interesting Litargus was detected near Hermigua, in 

 Gomera, by Dr. Crotch, during the spring of 1862. It is of precisely 

 the same type as the two Madeiran representatives of the group — 

 the L.pictus and pilosus ; though, in its small bulk, general structure, 

 very conical eyes*, and unstriated elytra, it is perhaps, specifically, 

 nearer to the latter than to the former. It may, however, be known 

 from them both by its paler (or more rufeseent) head and prothorax, 

 and by its elytra being ornamented with three, usually well-defined 

 (but occasionally broken up, or disjointed) reddish-yellow fasciae — 

 the first of which is basal and very oblique (running from either 

 shoulder to nearly the middle of the suture), the second postmedial 

 and somewhat obluniform (being less obhque than the preceding one, 

 and drawn in an opposite direction), and the third small and sub- 

 apical (being represented by two mere patches, or spots). It is more 

 elliptical and depressed than the European L. hifasciatus ; its head 

 and prothorax (the latter of which is narrower posteriorly) are more 

 rufeseent ; and its elytra have their markings more abbreviated late- 

 rally, and the two apical spots so largely developed as to form an 

 additional (or third) fascia.

* In the diagnosis given in my ' Ins. Mad.' I overlooked the anomalous fact 

 that the eyes of the Litargi are furnished behind with a few long, posteriorly- 

 directed sette. This peculiarity is correctly figured in the 347th plate of Stm-m's 

 ' Deutschlands Fauna ' ; yet I cannot see that it is noticed in any of the diagnoses 

 to which I have had access. It exists, however, in all the S2>ecies which I have 

 examined, — namely, in the European hifasciatus, the Madeu'an pilosus and (com- 

 pai'atively gigantic) j^ictus, and the Canarian trifasciatus.
