CATALOGUE OF ORTHOPTEROUS INSECTS. 



Body moderately slender, elongate, subcylindric ; the 

 mesothorax rather narrowed in front, entirely pale luteous 

 buff; a slender line extending down the middle of the tho- 

 racic and abdominal segments ; the body entirely destitute 

 of spines ; the head slightly tubercled behind. The an- 

 tennae long and slender. The meso- and metathorax 

 slightly dilated at the place of insertion of the legs. The 

 basal segment of the abdomen has the lateral connecting 

 membrane clothed with short brown setae set at right angles 

 to the body ; the eighth and ninth segments are short ; 

 the ninth with the outer terminal angles rounded, and the 

 apical margin notched in the middle ; the short anal styles 

 are visible at the sides ; the operculum extends to the ex- 

 tremity of the ninth dorsal segment, it is acute at the tip, 

 and very slightly swollen beneath in the middle. The legs 

 are of moderate length ; and all the femora are armed on 

 the under side near the tip with a small spine.

Another somewhat smaller specimen from the Swain- 

 sonian Collection has the membranous connexion between 

 the dorsal and ventral surfaces of the hinder segments fur- 

 nished with short setae.

The female of this species is tolerably well represented 

 by Stoll, whose figure exhibits the unarmed head, smooth 

 body, and angulated basal joint of all the tarsi. Fabricius 

 does not refer his Ph. ferula to Stoll, nor does his descrip- 

 tion — " M. magna, elongata ; corpore filiformi, aptero, 



viridi ; pedibus longitudine corporis ; femoribus angulatis, 

 posticis 4 apice spinosis ; antennae mediocres, apice fuscae ; 

 corpus totum laeve, glabrum, viride absque elytris et alis " 

 — quite satisfactorily agree with Stoll's figure. Lichtenstein 

 quotes both Stoll and Fabricius under his ferula, with the 

 character — " Ph. pedibus aliquanto corpore brevioribus, tar- 

 sorum articulo lmo triangulari ereeto ; anticorum pedum 

 femora et tibia apice subspinosce." Dr. Burmeister chiefly 

 distinguishes the female of B. Arumatia (ferula, F. Burm.) 

 from those of B. Calamus, muricata and simplex by the 

 smooth surface of the body. 



Mr. W. W. Saunders possesses an insect of large size, 

 which I refer to this species with some doubt. It is a 

 female, represented of the natural size, in PI. XXIII. fig. 4, 

 and measures 8£ in. in length ; its proportions being — 

 antennae, unc. 4 ; head, lin. 4 ; proth. lin. 3 ; mesoth. 

 lin. 24 ; metath. lin. 15 ; abdom. lin. 48^+lin. 8 + oper- 

 cul. lin. 2-±-=lin. 59. The head is oval, very convex, with 

 a minute tubercle on each side near the inner hinder angle 

 of the eyes. The body is smooth ; the thorax with a very 

 slender raised line on each side within the lateral margin ; 

 the fourth and fifth dorsal segments of the abdomen have 

 a small foliaceous lobe in the middle of the hind margin ; 

 the terminal segment of the abdomen is nearly square ; 

 the hind margin entire ; the two anal styles visible at the 

 sides. The operculum is granulated, and extends a quarter 

 of an inch beyond the extremity of the abdomen (fig. 4 a) ; 

 it is furnished within with two elongated slender filaments 

 bent upwards at the extremity, and extending also a little 

 beyond the abdomen. The legs are long and slender, 

 destitute of spines or lobes, and the basal joint of all the 

 tarsi is angulated in the middle of the upper edge. It is a 

 native of Columbia. If it should ultimately prove distinct, 

 it may receive the name of B. Remphan. 



6. (58.) Bacteria filiformis. 

 " Corpore filiformi, aptero, fuseo ; antennis nigris ; pe- 

 dibus corpore longioribus, inermibus" (Fabr.). " Pedibus 

 anticis inermibus, longitudine corporis ; antennis nigris, 

 corpore et pedibus fuscis, testaceo-annulatis ; tarsorum arti- 

 culis primoribus reliquis aequalibus," i. e. baud cristatis 

 (Lichtenstein).
