Descriptions of two new species of AROTES. 



BY E. T. CRESSON. 



Genus AROTES, Grav. 

 The North American species of this genus, as far as known, may be tabula- 

 ted as follows : 



A. Second recurrent nervure uniting with the cubital nervure: 



a. Color black, marked with yellowish : 



<;Hind femora black formosus. 



Hind femora honey-yellow /^.vicinus. L^ 



b. Color Iioney-yellow, marked with black venustus. 



B. Second recurrent nervure not uniting with the cubital nervure : 



a. Hind femora black, tipped with yellowish amcenus. 



b. Hind femora honey-yellow, tipped with black decorus. 



1. Arotes formosus, Cresson, Canadian Entomologist, i. p. 34, % . — The 9 close- 

 ly resembles the % in color and markings, but is more robust, and the wings 

 have a blackish spot beneath the stigma, as well as a round spot at tip. Length 

 6 — 7i li-nes.— Mass., 9,- Canada, %. (Coll. Am. Ent. Soc.) 



2. Arotes vicinus, u. sp.— Closely resembles the % of formosus, but is readily 

 distinguished by the color of the hind legs, which is pale honey-yellow, their 

 coxae above are black, as well as incisure between their femora and trochanters.: 

 their tarsi are concolorous with the four anterior legs, which are of a deeper yel- 

 low than those of foi'mosus, as also the markings of the body. Length 5 lines. 



Hab. — -Massachusetts. (Coll. Am. Ent. Soc.) 



3. Arotes venustus, n. sp. — -J- Honey-yellow, inclining to ferruginous, shi- 

 ning; face and orbits yellow: space behind antennae, covering ocelli, posterior 

 margin of occiput, short line on each side of face, and tips of mandibles, black ; 

 antennae black above, fuscous beneath, a broad annulus beyond the middle and 

 scape beneath, yellow; pleura, sides and basal suture of metathorax, black ; 

 each lobe of mesothorax with a more or less distinct black stripe; scutelluma 

 and disk of metathorax, yellowish; wings yellowish-hyaline, the anterior pair 

 with a blackish spot at tip; legs yellowish, hind coxae, femora and tibiae ferru- 

 ginous, tijJ of the former black; abdomen ferruginous, base of second and third 

 segments more or less, and sometimes part of the first, black; apical margin of 

 lirst and second segments yellow. Length 6 — 7 lines. 



"J, . Lemon-yellow, slender ; large transverse mark behind ocelli, broad stripe 

 on each lobe of the mesothorax, two spots at base of metathorax, base and apex 

 of posterior coxae, tips of their trochanters and femora, middle of first segment 

 of abdomen, and a broad band at base of remaining segments, black; antennae 

 longer than body, fuscous above; wings as in 9 j hind coxae and femora above, 

 pale fulvous. Length 5 — 6 lines. This may prove to be the "J, of a distinct spe- 

 cies, in which case it may be named occiputalis.

4. Arotes amcenus, Cresson, Canadian Entomologist, i. p. 34, % 9- — W. Va., 

 Peun., Mass., Canada. This is the most common species of the genus.
