PSYCHE. 



September 1S91. 



the male is the extremely long, slender, 

 bearded appendage to the abdomen, of 

 a tawny or dirty yellow colour. The 

 whole length of the male from the head 

 to the extremity of this appendage is T 8 ^ 

 of an inch ; this appendage is not quite 

 t 4 q of an inch; beirg nearly as long as 

 the whole body. Standing obliquely 

 on each side of the anus is a little fuli- 

 ginous tuft. The abdomen is some- 

 what fulvous beneath. The anterior & 

 intermediate extremities are fulvous, the 

 latter however have a dark patch on the 

 genicula & tibiae. The first joint of 

 the posterior tarsus is much more pilose 

 than in the female; the hair near the 

 union of the tarsus & tibia is fuliginous, 

 the remainder fulvous. The pectina- 

 tions of the antennas are slightly fus- 

 cous. This is the only male that I have 

 ever seen, & I found it on the identical 

 currant bush from which I had the pre- 

 ceding year taken the females. 



I have this season met with a species 

 of Cicindela that is new to me, & which 

 I cannot identify as any one of those de- 

 scribed by you in the Trans. Am. 

 Philos. Soc. Phila. 1S1S. I have called 

 it Cicindela (eryt/irog~aster)* obscure 

 fusca, elytris lunulis basi et apicis, 

 fascia intermedia flexuosa, punctisque 

 duobus albidis : abdomine femoribusque 

 viridis ; ano late rufo. Length half an 

 inch. Antenna? green at base. Head 

 cupreous, with two green abbreviated 

 lines between the eyes. Mandibles 

 white at the base, black at the points. 

 Lip white, with a single tooth. Thorax 

 cupreous obscure, with the margin & 

 breast green. Elytra obs[c]ure, some- 



*[See Harris, Entom. corresp., p. 2.] 



what cupreous, with a humeral & ter- 

 minal lunule, an intermediate flexuous 

 band, & two spots behind the band 

 whitish. Abdomen green, the hypo- 

 gastrium red. Feet obscure, thighs 

 green. I have only met with one spec- 

 imen, which was captured in a dry, 

 gravelly pasture. 



Prof. Peck taught me to define the 

 species in Latin & I have generally ad- 

 hered to his advice, though it savours 

 somewhat of pedantry. 



My friend, Mr. Fuller, has kindly 

 taken charge of a package containing 

 two boxes of insects for you. In box i , 

 (the bottom one) are some of the Cole- 

 optera which I have collected. They 

 are all numbered in order to facilitate 

 you in naming to me such as have been 

 described, & to enable you to indicate 

 the nondescripts. I have kept a cata- 

 logue to correspond, with arbitrary 

 names for all the species not as yet as- 

 certained. From the want of books, 

 plates, & access to other cabinets, but 

 more than all, from the want of time to 

 examine them I have made out but few 

 of the species. These I have added, 

 however, that I might from your infor- 

 mation and experience, render myself 

 doubly sure ; & also that I might learn 

 of vou to what genera they are to be re- 

 ferred, according to the System of Dr. 

 Leach in Brewster's Encyclop. I pre- 

 fer on most accounts his system to that 

 of Latreille in the Regne Animal of 

 Cuvier. Should it however be incon- 

 venient to you to follow the first, I must 

 content myself with having the genera 

 according to the second ; with such syn- 

 onyms as may be necessary. No. i of
