A new Species of Apateticus from Louisiana 



(Hem., Het.). 



By DAYTON STONER, State University of Iowa, Iowa City, 



Iowa. 



In a small collection of pentatomids recently sent me by 

 Mr. O. W. Rosewall, of the Department of Zoology and Ento- 

 mology, University of Louisiana, I found a very interesting 

 and peculiar specimen which I was unable to satisfactorily de- 

 termine. A short time ago I sent this specimen to Mr. H. G. 

 Barber, who confirmed my suspicion that it might be a new 

 species. It is quite unlike any of our other species of the 

 genus Apateticus and displays some interesting features. 



Apateticus ludovicianus new species. 



Elongate, narrow; general color above pale brown with a slightly 

 olivaceous tinge; head and anterior one-half of pronotum pale clay 

 yellow; humeri produced into acute, rounded points; costal margin of 

 hemelytra with a conspicuous ivory-white line extending from base to 

 membrane; median ventral spine very short, blunt. 



Head elongate, depressed, sides nearly parallel, the juga only very 

 slightly surpassing the tylus; an impressed line either side of the tylus 

 and just outside this and parallel to it is a rather regular row of 

 black punctures extending from base of head to tip 

 of tylus. Outside each of these rows is another 

 row of punctures extending from base of head to 

 near apex and which is partly interrupted by the 

 reddish ocelli; these punctures gradually become 

 smaller and a little before the apex of the tylus the 

 rows on either side become confluent. Dorsal sur- 

 face of the head between the rows of punctures 

 impunctate with rather sparse but fine subtransversc 

 lines. Lateral margins of head with a row of black 

 punctures extending from eyes to apex. An irregu- 

 lar, iridescent, greenish mark, deeply and coarsely 

 punctured on outer side of antennal tubercle in 

 front of eye. Eyes prominent, fuscous. Antennae 

 with basal segment very short, pale clay yellow, a 

 greenish-fuscous patch on outer side, which is con- 

 tinuous with the greenish mark on the tubercle: sec- 

 ond segment a little more than four times as 

 long as the first, vandyke brown, becoming dark- 

 er toward tip, covered with fine, pale yellowish 

 hairs: third segment about as long as" second, 

 blackish, paler at base and very thickly covered 

 with pale hairs. The remaining antennal segments are missing. 

 Rostrum heavy, pale yellow, darker toward apex, which reaches just 

 to posterior end of metasternum.
