548 "i\'EW YORK STATE MUSEUM 



Of the papers here enumerated that by MacGillivray and Hough- 

 ton is the only one treating of the hemipterous fauna of the Adiron- 

 dack region, and the few species there Hsted have been included 

 in the present list. Further collecting in this wild and mountain- 

 ous portion of our State will certainly add many species to the 

 present very imperfect enumeration of its interesting hemipterous 

 fauna, especially among those forms that are characteristic of the 

 Canadian region. This list is published with a full appreciation 

 of its fragmentary character but with the belief that it will make 

 a useful addition to our knowledge of the hemipterous fauna of 

 New York State. 



Homoemus aeneifrons Say. This insect proved to be very gen- 

 erally distributed and common in the Adirondacks where there 

 were low marshy spots with carices intermixed with the swamp 

 grasses. I took the young with the adults on a species of Scirpus 

 on the summit of Cobble Hill. On Sep. 22, 1902, I found them 

 equally abundant but then all seemed to have reached maturity. 



Sehirus cinctus P. B. I took this species occasionally wherever 

 I collected about Lake Placid but in one field immediately behind 

 the Isham House I found them in unnumbered thousands. The 

 weather was cold and when the sun would shine these insects, at 

 that time [Aug. 12] mostly in the larval state, would gather in 

 dense masses as large over and as thick as one's hand, on the sides 

 of logs and stones or wherever the bare ground would draw the 

 heat of the sun. A week later these larvae were rapidly reaching 

 the adult state. I found the food plant of this species was a low 

 hirsute labiate plant called "horse nettle" by the farmers about 

 there. 



Euschistus fissilis Uhler. Recorded from Axton by Professor 

 MacGillivrav. 



Euschistus tristigmus Say. Also taken by Professor MacGilli- 

 vray at Axton. I saw numbers of the young of this and other 

 pentatomids while collecting in August but the season was not 

 far enough advanced for me to obtain the adults. 



Coenus delius Say. Taken at Axton by Professor MacGillivray. 



Neottiglossa undata Say. I captured this species along the 

 road toward Wilmington Notch. In determining the material 

 taken by Professor MacGillivray I inadvertently wrote M o r - 

 midea undata and the species was so entered in his list. 



Cosmopepla carnifex Fabr. Taken at Axton by Professor Mac- 

 Gillivray. 



Podisus sereiventris Uhlcr. One fine large specimen of this 

 species was taken on the grounds of the Lake Placid Club on Aug. 

 15. It was also taken by Professor MacGillivray at Axton. 



Podisus maculiventris Say. This species and the next were 

 among the malcrial taken at Axton by Professor MacGillivray. 



Podisus modestus Dallas. With the preceding.
