Ground color of primaries, sordid white, with three dentated bands of rich

 The exterior margin is also scarlet, with the fringe dull white. Secondaries semi- 

 transparent, sordid white, witii the abdominal margin buff. Underside with the same 

 markings, but fainter. Thorax dull scarlet, streaked with sordid white. Abdomen, 

 ru^iy b:own. Kxp. wings, 40 mm. 



I !^. Las Vegas, N. Mexico. A. J. Bolter. 



An entomological anecdole has to be related with reference to this 

 species. I described this and Seirarclia Bolteri when in Chicago, 3 years 

 ago, and soon afterwards AL". Bolter sent colored drawings of both species 

 to Mr. R. H. Stretch. On m\' return home, some weeks later, I received 

 a letter from Mr. Stretch in which he savs : "Your Halisuiofa significans 

 is a synonym of Strecker's //. amhigiia." The manuscriitt of my paper 

 was then in the printer's hands, but I at once sent to have the description 

 stricken oin. I was in time to get this done, but it turned out, when it 

 was too late, thai .AL. Siretch meant that my Seirarclia Bolteri was the 

 synonym, and thus I redescribed one of Mr. Strecker's species, and left 

 the new one, which Lnow publish, unrecorded. This is t)ne of the most 

 beautiful of all Halisidotas and resembles in its coloration some of the 

 tropical forms. The unique type is in Mr. Bolter's collection. He was 

 good enough however, to furnish me with an exquisite drawing of the 

 insect. 



Inguromorpha, new genus. 



A genus closely allied to Cossus, and deemed by ]\Ir. J. B. Smith, 

 Id whom I subniillcd the sj)ecimen for examination, to be identical with 

 ii. He ])oints tiul the distinctions, however, and they are so marked and 

 the insect so unlike the ()rdinar\ species o{ Cossus in coloration and mark- 

 ings, that I think it wise to scjiarate it, which I do at least provisionally, 

 under the above name. I am fortified in this course also, by the opinion 

 of Dr. Packard, who has also seen the specimen, and who believes it to 

 be a new fjenus.
