THK OANATnAN KNTOMOLOOIST, 107 



with prostrate pubescence. Legs flavo-testaceous ; tibiae armed witii 

 spines, those on anterior tibipe stouter, piceous. Anterior femora (at least 

 in $ ) with large arcuate, bifid teeth as in A. spinifrons (Say). Antennae 

 flavo-testaceous ; second joint small, third joint longest, fourth and fifth 

 joints equal. Length ( 9 ), 2.75 mm.; humeral breadth ( $ ), 1.25 mm. 



Type, I 5 , South-east Nebraska (L. Bruner), in University of 

 Nebraska collection. 



This small form is easily recognized by the bifid tooth on the anterior 

 femora, by the size, and by the number of comb-teeth on the juga. 



Subfamily Pentatominae. 

 Euschistns latimargmaius, n. sp. (Fig. 11.) 



General appearance of E. fissilis Uhler, but form much broader 

 posteriorly. Colour pale yellow, distinctly punctured with fuscous or 

 black, the punctures tending more or less to coalesce and group themselves 

 irregularly, especially along the latero-anterior pronotal submargins, the 

 margins being calloused, impuuctate, pale. Juga longer than the tylus, 

 leaving the apex of the head distincily incised as in E. fissilis Uhler. 

 Antennae pale at base, fifth and distal half of fourth joint blackish; second, 

 third, fourth and fifth joints subequal, longer than the first joint; first joint 

 reaching at least as far as distal end of tylus. Latero-anterior margins of 

 pronolum concave ; humeral angles prominent, subacute. Tip of 

 scutellum paler, impunctate. Membrane immaculate, Hemelytra much 

 narrower than the abdomen, leaving connexivum exposed. Connexivum 

 broad, calloused, pale, forming a conspicuous lateral margin to abdomen 

 when viewed dorsally. Legs dotted with fuscous. Venter more or less 

 distinctly punctured ; punctures on pectus larger and more distinct than 

 those on abdomen. Angles of ventral abdominal segments darker, but 

 without conspicuous black points. Length ( $ ), 14. 5-15 mm.; humeral 

 breadth ( % ), 8-9. 5 mm.; breadth of abdomen ( ? ), 8 mm. 



Type, I 9 > Dewey Lake Township, Cherry Co., Nebraska, June (R. 

 H. Wolcolt). Paratypes, two 9 's, Brady Island, Nebraska, May, 1896 

 (L. Bruner) ; i 9 , Dismal River, Nebraska, July, 1889 (L. Bruner); i 9 , 

 Halsey, Nebraska, June, 190-, (L. Bruner, J. C. Crawford). Type and 

 paratypes in University of Nebraska collection. 



This form is very readily recognized by the head with the apex 

 incised, by the broad, pale, exposed connexivum, and by the immaculate 

 membrane. It is a sand-hills form, Dewey Lake Township, Brady Island, 

 Dismal River and Halsey being situated in typical sand-hill country. So 

 far, all specimens taken have been females.
