When do you think your Faunula will be prepared for the 

 press ? I am very anxious to have the use of it. I trust 

 you will have plates. Can you obtain the lithographic stone ? 

 If you can, you might have your own drawings printed in 

 Boston, by a man, who, I see by the papers, has just estab- 

 lished himself there for that purpose. 



HARRIS TO HENTZ. 



April 8, 182C. 



Your last letter received February 23d, is before me, and has 

 afforded me a subject of some useful study and reflection. 

 But before 'replying to its contents, I will recur to your pre- 

 vious communication in which, on a review of its contents, I 

 regret to find a query unanswered by me- You remark that 

 the insect marked by me, Ips fasciata, does not correspond with 

 the Fabrician description. This is true ; for Fabricius does 

 not appear to have known our insect. It is, however, correctly 

 figured and described by Olivier as Nitidula fasciata, and is 

 also described by Latreille under the same name. The genus 

 Ips is now restricted to a few Fabrician species allied to the 

 quadripustulatus of Europe, and some others, of which two or 

 three are natives of this State. Among these Ips sanguinolen- 

 tus {Nitidula sanguinolenta Oliv., Latr.) most nearly ap- 

 proaches fasciata in size and figure. The head and thorax 

 are black, the elytra reddish, each with a central black dot, 

 and black tip. Ips quadriguttata ? Fabr. {Nitidula quadrigut- 

 tata Olivier) most nearly resembles fasciata in markings, 

 but is much smaller, being; only between two and three twen- 



o / 



tieths of an inch in length. Our Ips fasciata might at first 



1 be easily taken for a miniature representation of two noble 



native species of the genus Engis, to which genus Ips is closely 



allied. One is Engis fasciata, the other, a still larger species,
