120 MAINE AGRICULTURAL EXPERIMENT STATION. 



but are otherwise characteristic. We have found but very few 

 specimens of this species about the greenhouse and no damage 

 has been traced to it. It occurs in a cellar in Orono under boxes 

 and barrels. It was probably brought into the cellar in dirt used 

 for storing celery and roots, and into the greenhouses with plants 

 brought in for the winter. It has been reported from Pennsyl- 

 vania, District of Columbia and Indiana. It is without doubt 

 indigenous to Maine. 



Paraiulus immaculatus Wood, 



Description : Deep reddish brown without spots ; antennae 

 rather long, slender and hairy; anterior margin of the head 

 notched; segments 48-51; dorsal plate channeled below; the 

 spine at the end of the body, large, hooked, robust, acute. 

 Length, i to 13^ inches. 



Remarks : Was originally described from specimens collected 

 in the Catskill Mountains, N. Y. It is found in the woods of 

 Maine, and also is quite common in the greenhouses at Orono. 

 As leaf mold and sphagnum from this locality are used in the 

 beds, this species was introduced that way. So far as we know 

 it has done no injury. 



Orthomorpha gracilis C. L. Koch. 



Description : Dark mahogany brown with the lateral laminae 

 prominent and yellow, giving the appearance of a yellow stripe 

 along each side. Length, about an inch. The male genitalia are 

 shown much enlarged in Fig. 3, and the head and terminal 

 segments enlarged two and one-half times in Fig. 4. 



Remarks : Widely introduced in greenhouses in Europe and 

 America. Found throughout the tropics and according to Prof. 

 O. F. Cook probably a native of the Malay region. At Orono 

 it is -found in abundance under pots in the sphagnum moss on the 

 shelves, and also about the roots of plants, near and in the holes 

 in the bottoms of the pots. Some times a half dozen specimens 

 were taken from under a single pot. This species has never been 

 found in the radish beds, but in a section of the house devoted 

 to tropical and other plants in pots. It was probably introduced 

 with some of the tropical plants. Whether it does injury to 

 these plants we are not certain. We are of the opinion that it 

 feeds on the decomposing sphagnum and other organic matter 

 present.
