Yosemitia maculicula Dyar. 



This seems to us to be merely a small, poorly marked specimen 

 of Zophodia stigmclla Dyar ; we have a long series from San Diego the 

 specimens varying greatly in size and distinctness of maculation but 

 representing apparently a single species. 



HOMOEOSOMA IMPRESSALE Hist. 



The original description calls for a single $ from Nevada as 

 Type; Hulst's revision states 'Colorado' as type locality and in the 

 Hulst Coll. there are $ and 2 'types' labelled 'Colorado' neither 

 agreeing well with the original description nor with one another. 

 Typical impressale is easily identified from the description and has 

 a rather well-defined t. a. black band composed of two more or less 

 confluent spots ; the so-called types do not show this but belong to 

 the rather immaculate form (equally common apparently) with only 

 the black discal dots present ; although probably conspecific we do not 

 think either of the specimens can be accepted as the true type. 



H. ELECTELLUM Hist. 



The original description called attention to the variation shown 

 in the type specimens in size and coloration and this is borne out by 

 the two type specimens from Blanco Co., Texas in the Hulst Coll., 

 one, the S, being small (17 mm) and a good match for what we 

 described later from Florida as differ tellum, the other, a 9 , much 

 larger (23 mm) and rather more ochreous tinted; the difference is 

 scarcely sexual as we have both sexes of both forms before us in long 

 series ; it may however be seasonal as we note that our small speci- 

 mens were taken mostly in early spring or late fall whilst the large 

 ones occur in summer ; Ragonot's name tcxancllum, judging by the 

 description and figure, would apply to the early brood with differ- 

 tellum B. & McD. as a synonym, whilst electellum may be used in 

 sens, strict, for the large summer form.
