394 ANNUAL REPORT OF NEW- YORK 



GRAPE. LEAVES. 



Abbot. To these I have recently added a ninth, and two addi- 

 tional species are now known to me, the characters of which may 

 briefly be stated in this place. 



109. Otiocerus Signoretii. Pale yellow; wing covers with a broad dusky 

 cloud-like stripe from the base to the middle of the inner margin, and extend- 

 ing thence obliquely across to the outer margin at its tip, and sending a very 

 broad branch to the tip of the inner margin; a large blackish dot anteriorly, 

 on the inner side of the dusky stripe, situated in the middle of the subaxillary 

 cell, and four dots on the outer side of the stripe, placed at the angles of an 

 imaginary square, the outermost one of these dots being in the middle of the 

 outer or costal cell; veins yellow, posteriorly red; wings whitish hyaline, 

 their veins red; keels of the upper side of the head minutely toothed, those 

 of the frontal and lower side edged by a slender coal black line. Length of 

 the body 0.20; width of the spread wings 0.60. The antennas are short, 

 scarcely reaching to the eye, and have but one appendage of about the same 

 length in males. This species is similar to Reaumurii, but the dots on the 

 wing covers are dijBferently placed. Two specimens from west of Arkansas, 

 from W. S. Robertson. 



110. Otiocerus Amyotii. Light yellow; wing covers pale sulphur yellow, 

 with a brown stripe from the base to the middle of the inner margin and 

 thence to the outer tip ; a row of blackish dots on the hind edge alternating 

 with the ends of the apical veins, and about six dots forward of the innermost 

 of these, placed on the tips of the subapical and on the bases of the apical 

 veins; three brown stripes on the thorax; an orange red stripe on each side of 

 the head, from the eye to the forward edge below the apex. Length 0.25, to 

 the tip of the closed wings 0.40; width of the spread wings 0.70. I have 

 hitherto supposed this to be the fVolfii of Kirby, but having recently captured 

 an individual of that species, the difi'erences between these two insects become 

 evident to me. The JVolJii possesses each of the characters above assigned to 

 the j^myotii, but the orange stripe on each side of the head is more faint and 

 runs obliquely upward to the apex of the head, where it ends in a short coal 

 black line, exactly as stated by Mr. Kirby; and the wing covers have three 

 distant blackish dots in a row, outside of the brown stripe, one of these dots 

 being placed near the base of each of the discoidal cells. In both of these 

 species the females have two long appendages to the antennae. The insect des- 

 cribed by Amyot and Serville, and by Spinola, under the name Stollii, certainly 

 is not the Stollii of Kirby, which is a dark colored species like the Dzgeerii; 

 but it is in all probability the same species which I have described above. I 

 have met with this insect in only two instances in this State, and once in New 

 Jersey. All the specimens were females and were found upon hickory leaves. 



111. Anotia Westwoodii. Another genus of insects peculiar to this country 

 and closely resembling the preceding, except that they are destitute of appen- 

 dages at the base of the antennae, was brought to light by Mr. Kirby, in con- 

 nection with the Otioceri. Only a single species of this genus, named jinotia
