52 FAMILY I. — SCUTELLERIDjE. 



XL Eurygaster Laporte, 1832, 69. 



Species of medium size and subdepressed oval form, having 

 the head about as broad as long, rounded in front ; cheeks as 

 long as tylus, sometimes (in foreign species) meeting beyond 

 it ; second and fourth antennals subequal, each about one-third 

 longer than third, fifth longest ; beak scarcely surpassing hind 

 coxae, second joint longer than third and fourth united, these 

 subequal, not flattened. Pronotum hexagonal, its lateral angles 

 broadly rounded, front side margins straight. Scutellum ob- 

 long, much narrower than the abdomen ; clavus and costal 

 border of elytra fully exposed ; connexivum wide, flattened, ex- 

 posed except at base. Osteole extended in the form of a straight 

 and narrow canal which reaches beyond middle of its support- 

 ing plate. Two species are known from 

 the United States, one of which occurs 

 in the eastern states. 



15 (19). Eurygaster alternata (Say), 1828, 

 pi. 43; I, 94. 



Oblong-oval, subdepressed. Above dull yel- 

 low marked with numerous fuscous punctures, 

 these aggregated to form many short oblique 

 lines on scutellum ; head often with two short 

 fuscous occipital stripes; antennae fuscous, the 

 basal joint paler; scutellum with a curved 

 narrow elevated smooth yellow line near base, 

 Fig. 10, x 4. (After Lugger). thig extended backward in the form of a fine 



median carina which is evanescent behind the middle; connexivum with 

 alternating spots formed of blackish punctures; under surface brighter 

 yellow marked with scattered fuscous punctures; legs yellow with black 

 dots. Pronotum finely, sparsely irregularly punctate, its disk with a 

 vague narrow smooth median line and a large oblong shallow depression 

 each side. Other structural characters as given above. Length, 7.5 — 9 

 mm.; width, 6.5 — 7 mm. (Fig. 10). 



Lake Co., Ind., May 12. Ranges from Quebec and New Eng- 

 land to Vancouver, south to New Jersey, Maryland, New Mexi- 

 co and California. In Indiana it appears to be very scarce, my 

 two specimens from the State being found beneath prickly 

 pear cactus growing near a swale in the dune region south of 

 Lake Michigan. On the other hand, Van Duzee (1904, 18) re- 

 ports it as "probably the most abundant and universally dis- 

 tributed Scutellerid found in North America. I once took it 

 in great numbers from sedges on the flats bordering a stream
