452 FAMILY VI. - ACRIDID.K. - THE LOCUSTS. 



Somes says it is very rare in Minnesota, but that he has taken 

 it in northern Iowa in low thickets of willow. Bruner states that 

 in Nebraska it is "found in rather small numbers in oak groves in 

 the extreme eastern part of the State." 



In Ontario the grizzly locust has been recorded only from To- 

 ronto and DeGrassi Point. Of its habits at the latter place E. M. 

 Walker (1901, 22) has given an interesting account as follows: 



"I found them most numerous on dead stumps and logs, in a wood of 

 second growth white pine. They were sometimes seen on the trunks and 

 branches of living trees, but most often on the stumps and fallen trunks of 

 the old forest, and on the pine rails of a snake fence enclosing the wood. 

 They were found only on the borders and more open parts of the woods, 

 where they were to be seen upon almost every stump. I have seen ten fe- 

 males on a single stump. It is in these dead stumps and logs that the fe- 

 males deposit their eggs, in which operation I have observed them re- 

 peatedly. The female chooses a crack in the wood or an old beetle boring 

 of suitable size and lowers her abdomen down this, sometimes nearly as 

 much as an inch. Sometimes when the hole is of a large size, only the 

 head and legs of the insect can be seen above it. Unlike CJiloealtis con- 

 spersa, the female of M. punctuJatus apparently never bores herself, unless 

 merely to make her way through any loose rubbish that might be obstruct- 

 ing the hole. She generally chooses sound or only partly decayed wood. 



"I managed to obtain several fragments and one complete packet of 

 eggs. The latter was fixed by the cement substance at its lower end to 

 the wall of the beetle-boring three-eighths of an inch in diameter. It was 

 attached at a distance of about three-quarters of an inch down the hole, 

 and except at the lower end, which was imbedded in a depression in the 

 wall, the packet was quite free. It was covered with a rather thick coat- 

 ing of a porous or vesicular cement substance, which also filled all the 

 spaces between the closely packed eggs. The latter were twenty-three in 

 number, and their arrangement was in general in a longitudinal direction, 

 the anterior ends pointing toward the free end of the packet, but was 

 otherwise irregular. The eggs are 4 to 4.8 mm. long, elongate-elliptical in 

 form, finely and densely punctate and reddish-brown in hue." 



The Calo/itcniis (/risen s Thomas (1872, 454) and the C. li 

 Scudder (18751), 470) are both synonyms of J7". pintctulatus. 



209a. MKLANOPLUS PUNCTULATUS ARBOREUS Scudder, 1897b, 31. Southern 



Grizzly Locust. 



Larger than typical punctulatus. Color much as there. Metazona 

 shorter and broader, its hind margin more broadly obtuse-angulate. Fur- 

 cula evident, consisting of a "pair of slight triangular projections at the 

 inner angles of the divided last dorsal segment and overlying the ridges of 

 the supra-anal plate." Subgenital plate with apical tubercle larger, more 

 inflated and more prolonged upward. Length of body, $ , 27.5 30, 9 ,
