 The species contained in it are the fol- 

 lowing; we have prefixed the number 

 of the pages on which they occur, and 

 appended the volume and page of the 

 Complete Writings when found there.

 This tract is not to be confounded 

 with the very similar Barabino pamphlet, 

 published in the following year, describ- 

 ing nineteen species, although printed 

 at the same press and evidently with the 

 same type. 



The descriptions of the two over- 

 looked species are here carefully repro- 

 duced, with some notes regarding them 

 kindly sent at my request by Mr. P. R. 

 Uhler and Baron Osten Sacken. 

 [11.] Pentatoma, Oliv. Latr. 

 P. maciilivt-iilris, llemelvlra with a line at 



tip; venter witli five series of black points. 



Inhab. U. S. 



Body yellowish or pale brownish, with 

 dense, rather large punctures : thorax acutely 

 angulatedeach side behind the middle; Iteme- 

 lytra having an abbreviated fuscous line at 

 tip of the membranous portion : antcnncp, 

 first ioint short; 2d longer than the third: 

 tergttm on the lateral maigin with a black- 

 ish dot on each incisure : In^Jieaih Yellowish : 

 feet immaculate; thighs sometimes having 

 numerous minute blackish points; anterior 

 tibia: with an obvious spine over the slight 

 emargination : vcntervi\\\\ five obvious series 

 of small black dots. [12.] 



Length less than two-fifths of an inch. 



This is a common insect in many pans of 

 the Union. The anterior central angle of 

 the venter is produced between the bases of 

 the posterior feet as in Acanthosoma of Cur- 

 tis ; but it does not agree with that genus in 

 the more essential characters of the antennie 

 and tarsi. 



Mr. Uhler writes : Upon comparing 

 the species of Podisus with the printed 

 slip sent me, I find the description fits 

 very well the P. spinosus Dallas. The 

 description does not agree with any 

 other of our North American species, 

 as at present known. The humeral 

 angles in P. serieventris Uhl. are not 

 " acutely angulated," but they are in P. 

 spinosus. — P. R. Uhler. 



[ig.] TvpETA, Meig- 



T. trifasciata, Green; wings with three 

 bands. 



Inhab. Louisiana. 



Body brassy-green, polished : vertex green- 

 ish : front pale ferruginous, pruinose : anten- 



me : kypostonia dark livid, pruinose : 



mouth pale ferruginous : stethidium entirely 

 brassy-greenish : wings yellow-white, a black- 

 ish band on the middle obsolete at the thinner
