2617 Oecanthus Californicus Sauss. 



Frequeut at Clai-cmont, California. Det. Eehn. 

 261G Oecanthus marcosensis Baker n. sp. 



Specimens collected at San Marcos, Nicaragua and of the same 

 general habitus as californicus had been doubtfully referred to that 

 species by Eehn. No. 2617 he had determined as true calif (.rnicun But 

 rnorcosenn ^ differs widely in the majority of the specific characters, 

 coloration, form of body, structure of antennae, etc., though it is 

 evidently a near relative. Type in my collection. 



Length 18 mm. Color a faded brownish, darker on the posterior legs. 

 The antennae are stout, the two basal joints brownish, and each with a 

 Blender, longitudinal, dark brown dash beneath; the flagellum is straw 

 colored and with short white pubescence; joints 3 and 4, 6 to 10 inclusive, 

 12, and 16, are short and subequal; joints 5, 13, and 17, are slighMy 

 longer and subequal; joints 11, 14, 15, and 18 and suceeding joints, arc 

 about twice as long as the smallest joints and subequal in length. The 

 maxillary palpi are about as long as the head, joints 3 and 4 subequal, 

 joint 5 longer and most swollen in the apical half. Labial palpi small, 

 the third joint longer than the first two together and but slightly swollea 

 towards the normally rounded tip. Pronotum narrowed anteriorly, the 

 sides neither strongly depressed nor much expanded; near the median 

 line are three pairs of small longitudinal depressions; near the front 

 margin on either side is a short semicircular depression, while posterio- 

 to these are a pair of long, curved, deep longitudinal depressions. The 

 tegmina are 14 mm. long by 5.5 mm. wide at the widest place; on th-? 

 reflexed portion are fourteen oblique veins. The wings reach to the tips 

 of the tegmina. The cerci are rather stout, extending to the wing tips, and 

 covered with rather long white hairs of varying lengths. The hind femora 

 have three longitudinal series of short, oblique, straight brown dashes 

 on the outer side, while both femora and tibiae are sprinkled with minute 

 brown dots; the tibiae bear five pairs of large spines besides the numerous 

 small teeth; the apex of hind tibiae and the hind tarsi are thickly 

 covered with a short golden pubescence.
