was usually dryer than the surnumdini: soil. At different timea 

 the f eniah's were seen filling the burrows as well ;is e\ravatin-- 

 them; the quantity of sand removal and tin- rapidity with which 

 its removal is accomplished can not help but atti-act admiration 

 for these wasps, especially when it is known that the larvaF 

 chamber is usually located six or more inches below the surface 

 of the ground. 



TIIH SMALL HORSE GUARD. 



(Bembex belfragei Cresson). 



This is a member of the same family as the last, but is a 

 much smaller insect. So far as observed, its habits and life his- 

 tory are similar; its burrows are made in similar locations and 

 the food of its larvae is composed of different species of Diptera r 

 a large proportion being horseflies. A difference is noted, how- 

 e\er, in the places where it procures these horseflies, for, in- 

 stead of catching them almost entirely around stock, it picks 

 them up in the marshes and fields, not hesitating to fly out over 

 the water to procure specimens that it finds clinging to grasses 

 aud sedges. Therefore the male horseflies are taken much oftener 

 than by the horse guard. In 1903 this species appeared to be 

 much more common than in 1905. It is one that should be widelv 

 known and given as much protection as possible. 



SAY J S SPOTTED WASP. ^ ^ 



(Crabro lO-w/n/Mi/x Say.) ' &&' 



This is another of the solitary wasps which has been oh 

 served catching horseflies. Its nest was not located, but it is 

 known that various species of its -cnus make their nests in- 

 woody plants, especially raspberry and blackberry. 1'eckham 

 found that another wasp of this i>vnus (Cnihrn stirpiCi 

 visioned its nest with various speci- s of (lies.

( rinunn-na t<ib<utir<>nis Ashincad.) 



Some years ago Hart reared this parasite from the . S 

 our large black horsefly.* Then- is probably more than Dne 



*Tabauus atratu*.
