NOTES ON THE SPECIMENS OF SOLENOBIA TBIQUETEELLA AND 

 CHALYBE PYEAUSTA IN THE DOUBLEDAY COLLECTION. 



BY JOHN HARTLEY DURRANT, F.E.S., Mf.mb. Sod. Ent. dk France. 



Having read Mr. Barrett's notes on the specimens of Solenohia 

 triquetreJla in the Doubleday Collection {vide ante, 128-9) I visited 

 the Bethnal Green Museum last June with named exponents of all 

 the allied species, and also of those near Chalybe pyransta. The 

 Doubleday specimens representing Solenohia triquetreUa are quite 

 distinct from triquetreUa, ¥. R. (which is probably the same as tri- 

 quetreUa, Hb.) ; the cases differ quite as much as the perfect insects. 

 The Doubleday specimens appear to me to belong either to a strongly 

 marked form of Wockii, or more probably to a species intermediate 

 between Wockii and inconspicueUa, having the facies of the latter 

 •with the colouration of the former, but with a more distinct pattern. 

 There are no specimens in the Zeller or AValsingham Collection which 

 quite agree with them, but until a series is obtained it will be im- 

 possible to decide whether they represent a new species. 



The specimen labelled Chalyhe pyrausta is the true Ethmia py- 

 rausta, Pall. ; it is rather small, but is readily recognised by the 

 discal spots being arranged thus • . ", it could, therefore, only be 

 confused with. JlavitibieUa, H.-S., from which it is at once separated 

 by the greater number of yellow abdominal segments and by its paler 

 colour: andalusica, Stgr., and chrysopyf/a,7j.,(W^Gv in having the discal 

 spots thus •• •, and are separated inter se by the greater number of 

 yellow abdouiinal segments found in andalusica. The history of this 

 specimen is unknown, but as only one specimen has been taken in the 

 British Islands, it is either that captured by Mr, Buxton (which has 

 disappeared), or it is a foreign exponent of the species.
