PSYCHE.

of which are Iiaii-Hke, acute, while 

 others are blunt and curved. The sur- 

 face in general is covered with the usual 

 fine pile. The median area is bordered 

 by a pile-covered area, but along this 

 region no sense-pits, cups, or rods could 

 be detected with a power of 400 diam- 

 eters ; over the region where they 

 usually occur were to be seen scattered 

 conical setae. 



Order Ortiioptera. 



A xvingless B I ait id from Florida. 

 — The labrum is full and rounded on the 

 front edge, with no indications of a 

 median suture. The surface of the 

 epipharynx is finely and densely pilose. 

 There are no sense pits, cups or rods 

 visible. 



Blciiia, a large winged species 

 from Cuba. — Front of the labrum 

 slightl} excavated. The epipharynx is 

 provided on the front edge with very num- 

 erous short, stout, minute setae, which 

 are cui^ved downward, and form when 

 looked at vertically, a pavementTike 

 mass ; beyond on the extreme edge is a 

 dense fringe of short slender rodTike 

 bristles. The surface elsewhere is 

 finelv pilose, the median region not 

 being bare. On each side of the mid- 

 dle is a curved I'ow of stilT defensive 

 spines ; at the distal end of each row is 

 a sensitive field, containing 20 taste-cups 

 on one side and 23 on the other. Near 

 the front edge of the clypeal region are 

 two more sense-fields, situated on each 

 side of the median line, there being 35 

 taste-cups in each field. The taste-cups 

 in this species are rather smaller than 

 usual. 



Spectrum hlvittatum Say. — In a 

 specimen from Indian River, Fla. the 

 front edge of the labrum is entire, but 

 along the middle are traces of a median 

 suture. The middle region of the 

 epipharvnx, and the epipharyngeal lin- 

 ing of the clvpeus are covered with fine 

 and coarse setae, but there is no bare 

 space, and no sense-pits are to be de- 

 tected. (Those that at first appear to 

 be such are ordinarv cells with the setae 

 broken ofi'. ) 



Ca/u/ntia pellucida Scudd. — The 

 labrum is notched, but the edge is plain, 

 not bearing any I'ods or bristles on the 

 border of the excavation, or elsewhere 

 on the labral margin. There is a well 

 defined short median suture in the mid- 

 dle of the labrum which sends poste- 

 riorly two forks. 



The epipharynx is free from hairs 

 along the middle, and near what cor- 

 responds to the front edge of the cly- 

 peus, are two sensitive fields, each con- 

 taining about 35 taste-pits. Just in 

 front under the suture between the cly- 

 peus and labrum are two similar fields, 

 each containing from 40 to 42 taste-pits. 

 There are none in front of these. 



Xiphidium brevipennis Scudd. 9 • 

 — The epipharynx is slightly notched at 

 the end in the middle and the sinus filled 

 with slender setae. The median line 

 forms a slight furrow, while the surface 

 of the epipharynx in general is covered 

 with fine rather stiff' short setae. 



Along each side of the median line 

 on the anterior half of the epipharynx 

 are scattered about 30 taste-cups, mostly 

 without, but some bearing rather large 

 and long setae. At the base is a scat-
