latipennis Riley ^ temporarily, as the most nearly related form. But this 

 can scarcely be that species as the description will indicate. The type 

 is in my collection. 



Length 15 mm. Color, the faded yellow common to many species of 

 Oecanthus. The anterior and middle femora are pale brown. The anteix- 

 nae are clear shining amber color; the two basal joints are brown and 

 each has on the under side an ivory white area with a small round dark 

 brown dot at center; the flagellum is very slender, about 16 mm. in length 

 and very minutely and sparingly pubescent; joints 2 to 11 inclusive, of 

 the antennae, and 14 and 15, are short and subequal in length ; 12 and 13, 

 and 16 and immediately succeeding joints, nearly twice as long a-s those 

 in the first lot. Joints 3 and 4 of maxillary palpi equal; joint 5 as long as 

 first three together and medially somewhat swollen. Basal joint of labial 

 palpi small, second slightly more than twice as long, third as long as first 

 two together and gradually enlarged to a truncate tip. Pronotum narrovi^- 

 ed anteriorly, with two small slender curved longitudinal depressions 

 laterally on disc; the sides are first strongly depressed and then expand- 

 ed. The tegmina are 12 mm. long by 4.5 mm. wide at the widest place; 

 the reflexed lateral portion has eleven oblique veins. The wings exceed 

 the tegmina by 1 mm. The cerci attain the tip of the wings and ar-3 

 thickly pubescent with silvery white hairs. The hind tibiae bear five 

 pairs of large spines besides the numerous small teeth. 

 3428 Oecanthus Relinii Baker n. sp. 



With No. 1302 I had placed a specimen taken at Stanford Uni- 

 versity, California, which was almost identical in general form. On 

 examining it critically T am surprised to find that it differs in almo&t 

 all the specific characters in use in the genus. The type will remain in my 

 collection. 



Length 14 mm. Color as in rileyi. Anterior and middle femora of 

 the same color as the rest of the body but the hind femora are brownisj. 

 The antennae are quite stout, 22 mm. long, opaque, brown in color anl 

 covered with a tolerably dense minute pile; the articular nodes are white, 

 producing a ringed appearance; the two basal joints are yellow; the 

 first has beneath and within a heavy black longitudinal stripe, and a 

 roundish black spot apically and outwardly; the second joint is almost 

 covered beneath with a large black spot which is notched with yellow 

 apically; joints 2, 3, 5 to 8, and 10 and 11, are short and subequal, 

 joints 4 and 9 are once and a half as long, joints 12 and 13 are twice as 

 long, 14 the same length as the first lot, while 15 and succeeding joints 

 are again long and subequal. Palpi and thorax about as in rilfyi The 

 tegmina are 10.5 mm. long by 4 mm. wide a the widest place; the reflexed 

 lateral portions have twelve oblique veins. The wings exceed the tegmina 

 by 1 mm. The cerci are as in rileyi The hind tibiae bear six pairs of 

 large spines besides the numerous small teeth. The apices of the hind 

 tibiae and the hind tarsi are piceous.
