at intervals of seventeen years, while another comes every thirteen 

 years. These insects are frequently carried off by the digger-wasps as 

 food for their young, in tlie same manner as the Cicada pndnosa before- 

 mentioned. Madam Meriam states that one species of cicada is very 

 destructive to the coffee-plants in Surinam, but our species do not appear 

 to do much permanent injury, excepting when exceedingly numerous, 

 and then only to the terminal shoots and branches, where the eggs are 

 deposited. Tlie general color of the seventeen-year cicada is of a rich 

 yellow or orange-brown, varied with a darker color; the outside edges 

 of the wings are of a light ricli buff or orange brown, by which alone it 

 can be distinguislied from its relative Cicada pniinosa, which is of a 

 green color, v/ith the edges of its wings also green. It is also much 

 smaller, the figure of the insect oSTo. 2 being taken from an extra large 

 specimen. 



Otiocerus coqiiehcrlii is a small insect of a somewhat elongated form 

 and having a small projection in front, resembling the lantern No. 3. 

 of tho true fulgora or lantern fly of Surinam, but on a verj' (^^^^ 

 diminutive scale ; it feeds on tbe wild grape, beech, and oak ; it ' -^^ 

 is 0.35 to 0.42 in length, and of a yellowish-white color, with a bright car- 

 mine red stripe running longitndinally along each side of its wing, and 

 which stripe is usually forked at its hinder end. This insect is 0.42 

 in length ; it was quite rare near the Maryland college, and was taken 

 by beating among the bushes with a common insect-net. The genus 

 Otiocerus is remarkable for possessing long slender cylindrical append- 

 ages attached to the base of the antennae. Another insect of the same 

 genus, Otiocerus amyotUi, is found on hickory and walnut. As these 

 small insects, however, do very little injury to the farmer, we will 

 not propose remedies, but refer to the remedies for Tcttigoiiia, JErythro- 

 neura, and Aphis, which will answer equally well for most of the tree- 

 hoppers should they become very numerous and troublesome. 



A small Fulgora — Scolops {Fulgora Say) sulcijpes — is a most No. 4. 

 singularly-formed insect; the front part of its head being 

 much prolonged, and projecting upward like a thin curved 

 horn. When dried in a cabinet it is of a light drab color, and 

 is found among brambles and weeds in meadows. It is not very rare in 

 the neighborhood of the Maryland Agricultural College in. July and Sep- 

 tember, and may readily be taken in a sweep-net; but as it is very 

 active and leaps well, it frequently escapes capture; in length, to the 

 tip of its hori]-likc prolongation, it measures 0.40. 



A small homopterous insect, PhyUoscelis atra (var. jMllescens) is No. 5. 

 not uncommon among the brambles and weeds in meadows in Mary- 

 land ; it is of a singular round or broad oval shape, being about ^ 

 0.20 in length by 0.13 in breadth; the fore thighs are much thick- m 

 ened, and the hind tibite or shanks are quite long and spiney on ) 

 their outer edges, and are fitted for leaping ; it is very active. The color 

 of this insect is black, having two orange-brown stripes on the thorax, 

 two longitudinal stripes of the same color on tho outer wings and on 

 the border of the scutel. There is another variety, entirely black, found 

 in the same situations, and the two varieties are frequently taken at the 

 same time when sweeping for other insects. 



The genus DeJphax is here represented by a small insect, 

 Belphax carinata, in form somewhat resembling a very small 

 cicada, having wings sloping like a roof, almost transparent, 

 and veined, and bearing three oblique bars of a brown 

 color, meeting at the ridge. It was taken when beating 

 In grass and meadows; length, 0.20; it is likewise found
