surpassing the base of the head by one half its length. Pronotum smooth, 

 oblong ; sides straight behind, rounding anteriorly slightly constricted by a 

 broad punctured band behind the middle ; anterior lobe with a deep long- 

 itudinal furrow ending before in a feebly punctured submarginal line. 

 Elytra very short and narrow, reaching to the base of the second dorsal 

 segment of the abdomen; testaceous brown with an angled fuscous shade 

 bordering the claval suture and apical margin ; membrane narrow, whitish. 

 Length 5-7 mm. 



Described from fifteen examples which were swept from 

 marsh grass along the shore of Tampa Bay at St. Petersburg. 

 This species may be distinguished by its castaneous color and 

 the oblong smooth pronotum with a conspicuous longitudinal 

 discal furrow. 



74. Ischnodemus lobatus n. sp. 



Closely allied to the preceding. Black, covered with a minute grey 

 pubescence; base of the antennae, rostrum and legs rufous ; lobate posterior 

 angles of the pronotum and the elytra testaceous, the latter obscurely veined 

 and clouded with blackish posteriorly. Membrane short, reaching the 

 middle of the second segment of the tergum ; white with two or three 

 fuscous veins. Pronotum rather short, hind edge deeply arcuated ; sides 

 parallel posteriorly then abruptly approaching to the narrow apes ; median 

 longitudinal furrow nearly obsolete ; disk anteriorly with a large smooth 

 intensely black mark on either side. Antennae stout, basal joint short-oval, 

 but little thicker than the remaining joints ; second and fourth subequal ; 

 third a little shorter. Rostrum almost attaining the intermediate coxae ; 

 second joint surpassing the base of the head by more than half its length. 

 Length 6 mm. 



Described from one brachypterous female taken at Estero. 



75. Blissus leucopterus Say. 



One small macropterous example of the common chinch 

 bug was taken at Ft. Myers and a larger brachypterous one at 

 Sanford. I was constantly on the lookout for this insect but 

 saw only these two. 



76. Geocoris bullatus Say. 



Of this species I took one female at Crescent City, a male 

 at Tampa and another at Estero. It evidently was rare in 

 Florida but farther north replaces punctipcs. 



77. Geocoris punctipes Say. 



Abundant everywhere I collected in Florida. It strongly 

 resembles bullatus but may readily be distinguished by the
