SCUTELLEROIDEA OF IOWA dd 
Abdomen without longitudinal ventral suleus; rostrum aver- 
aging shorter; juga without lateral tooth....... PENTATOMINI 
Tribe Mrcipuni (Distant) 
Sides of abdomen anteriorly with a transversely placed strigose stridulat- 
ing spot. 
This is a small tribe of about fifty species which is best repre- 
sented in the Australian region. A single genus and species is 
recorded from North America. 
Genus MECIDEA Dallas 
1851. Mercipra Dallas, List Hem., I, 181 and 139. 
This peculiar genus containing only six forms has one repre- 
sentative in North America and it has also been recorded for 
Towa. The other members of the genus are divided among the 
Oriental, Ethiopian and Palaearctic regions. The characters 
of the genus may be thus summarized: 
Body elongate linear. Head somewhat pointed anteriorly, the juga longer 
than the tylus, meeting or almost meeting in front of it but with the tips 
somewhat divergent. Eyes large, globose. Antennae of five segments; 
second antennal segment as long as or longer than the others, expanded 
on inner side. Rostrum reaching hind coxae; second segment longest, as 
long as the two apical segments together. Scutellum triangular, very long, 
narrow and acute.

General form very long, linear. Color pale yellow,thickly, rather uni- 
formly punctured with fuscous; a uniform, narrow fuscous line extending 
backwards on either side of the ventral aspect of the body from the base 
of antennae to near posterior margin of last complete abdominal segment. 
Head very long, narrow, pointed anteriorly; juga pale yellow, punctured 
with reddish brown, surpassing tylus in front of which they are contiguous 
with the apices slightly divergent; tylus pale yellow, the slightly im- 
pressed line on either side fuscous and more finely punctured; the pale 
yellow of the tylus and juga is carried posteriorly across the pronotum 
in three diverging rays and the median line is continued to the tip of the 
scutellum as a pale calloused ruga. Eyes prominent. Ocelli large, a little 
in front of the posterior margin of the eyes. Rostrum slender, reaching 
beyond midcoxae. Antennae fuscous, heavily punctured, tapering towards 
tip; second segment longest, expanded on inner side so that it appears 
triangular in outline. Side pieces of thorax irregularly, deeply punctured.
