PSTCHE. 



["November 1S93. 



located a few hundred yards to the 

 south at the base of the north slope of 

 the wooded hills. The scutellerid was 

 very numerous on the Nicotiana, and 

 lives on the juices of the plant. About 

 thirty adults were taken, but only one 

 larva. This was the only larva seen at 

 this date, but hundreds of the adults 

 could have been collected. Some ants 

 were observed, which appeared to 

 linger about the scutellerids. 



Specimens of the latter were sent to 

 Mr. Uhler and Dr. Riley, and deter- 

 mined by them as Corhnelaena extensa 

 Uhl. This record is of interest as 

 noting a scutellerid which affects 

 Nicotiana. I know of no previous 

 mention of a member of this family of 

 insects living upon this plant. 



The adult of C. extensa is shining 

 black, with the hemelytra widely, 

 almost wholly creamy on the sides. 

 The larva is very similarly colored, 

 being also black with a patch of 

 creamy on the sides of body, the hem- 

 elytra being not yet developed. It may 

 be more definitely described as follows : 



Larva of Corimclaena extensa. — Length, 

 i£mm.; width, 1 mm. Body clothed some- 

 what sparsely with short pubescence. Head 

 triangular in outline from above, narrower 

 than thorax, shining black above and below, 

 the usually invisible membranous neck-like 

 portion which attaches the head to the thorax 

 being pale or light colored. Eyes brownish. 



Antennae pale-colored; pubescent, 4 -jointed, 

 last joint longest and stoutest, three basal 

 joints nearly same length and size. Beak 

 elongate, reaching beneath body as fir bick 

 as origin of hind pair of legs, pale colored, 

 3 -jointed, basal joint a little the longest, last 

 two joints nearly the same length, the second 

 joint a little stouter than the last. Thorax 

 about one-third broader than head, shining 

 black above and below. Legs pale colored, 

 except femora which are mostly darker. Ab- 

 domen as wide as thorax, rounded behind, 

 vaulted and convex, cistudinate (in the dried 

 specimen), exposed and bare, widely shining 

 black on the median portion longitudinally, 

 narrowly so on the lateral edges, between 

 the two with a lateral longitudinal stripe 

 of creamy whitish which gradually narrows 

 to a point posteriorly. Ventral surface 

 of abdomen very concave, and showing 

 same coloring. Scutellum and wings 

 wholly undeveloped. 



One specimen, July 6, on Nicotiana. 

 Arizona. 



In the adult the last joint of antennae 

 is no longer nor larger than the preced- 

 ing two joints, to each of which it is 

 nearly equal. The legs are almost 

 wholly blackish or brownish, except 

 the tarsi and tips of tibiae. The beak 

 is brownish and 3-jointed, antennae 

 pale. Whole upper surface of head, 

 thorax and scutellum is dark metallic 

 green. Wing covers are extremely 

 narrow, creamy except a narrow dark 

 green line on inner edge which 

 broadens at base. 



A new Entomological Journal. — The Most of the articles, as is fitting, bear particu- 



New York entomological society began early lar reference to the insects of the neigh-

nal, of which three parts have already special value in this respect; besides which 



appeared, extending to nearly 150 pages. are not a few papers of permanent interest.
