428 A New Species of Cicada, from the Cascade Mountains. 



flower by Dr. Welwitsch in the month of September, and with 

 ripe cones by Mr. Baines in the month of May. 



From careful microscopical examination and comparison of 

 parts. Dr. Hooker places this most extraordinary plant in the 

 natural order Gnetaceas, and considers it to have a very close 

 affinity with the genera Ephedra and Gnetum. 



Independently of its high scientific interest, the Welwitschia 

 is valueless. There is no part of any economic use. Its 

 leaves are tough, but leathery, and not softly fibrous, and 

 therefore not adapted for cordage, weaving, or any similar use. 

 Its trunk, though tough, is of such an uneven, fibrous grain, 

 that the saw seems rather to tear it asunder than to cut it ; and 

 added to this, the general irregularity of its growth, it is no 

 wonder that the plants have been allowed to grow on in their 

 quiet, sandy desert-home, unmolested by the natives, and, in 

 consequence, up to the time of its discovery, carefully hidden 

 from the eye of civilized man. It is, however, one of the 

 many proofs of the value of scientific explorations, which are 

 happily becoming more appreciated in these days. 



A NEW SPECIES OF CICADA, FROM THE CASCADE 



MOUNTAINS* 



BY J. E. LORD, F.Z.S. 



I discovered this new and beautiful Cicada for the first time 

 on the banks of the Pend-orielle River, on the eastern slope 



* Order, Hemiptera; Sub-order, Homoptera ; Fam., Cicadidtz ; Genus, 

 Cicada (Linn.) ; Nov. Species, Cicada occidentalis (Walker). 



Sp. ch. Nigra subtus, albido tomentosa, facei et prothorace, testaceo marginatis, 

 mesothorace lituris duabus cuneatis, lateribus margineque postice testaceis, segmen- 

 torum abdominalium, marginibus posticis subtus luteis, femoribus libiisque tes- 

 taceo vittatis, alis vitreis, basi rufis. 



Cicada. Black under side, with shining whitish tomentum ; head much 

 narrower than the prothorax ; transverse furrow in front testaceous ; face trans- 

 versely ridged on each side, with a testaceous border ; prothorax with four 

 oblique furrows, which converge hindward ; border testaceous ; sides with slightly 

 gilded pubescence, dilated and rounded hindward ; mesothorax with two V 

 shaped testaceous marks, which extend from the fore border to the disk, and are 

 indistinct except at the tips ; sides and hind border testuceous; abdomen thinly 

 clothed with shining whitish pubescence ; hind borders of the segments luteous 

 on each side and beneath ; dorsal opercula testaceous ; sheaths of the ovipositor 

 greenish ; femora and tibia with testaceous stripes ; fore femora incrassated, with 

 two teeth on the under side ; wings vitreous, bright red at the base ; veins black, 

 greenish towards the base ; fore wings with a greenish costa ; first and second 

 transverse veins slanting outward — first parted by more than twice its length 

 from the second, third and fourth slightly slanting inward. Length of the body 

 twelve lines. This species is smaller than C. septendecen, to which it has much 

 general resemblance.
