Type.— Univei'sity of Kansas. 



Type locality. — Lawrence, Kansas. 



One 9 taken at night in May, by E. S. Tucker. 



Idectliis biconjniictus u. sp. 



Closely related to Limnerkmi conjunctus Cress., from which it 

 differs in the areola, which is separated from the petiolarea, in the 

 angular area, color, etc. 



'^ . — 6 mm. — Head as in Limnerium lawrencei, except as follows: antennae 

 thirty-two jointed ; cheeks as wide or very nearly as wide as the eye. 



Thorax. — With characters italicized in L. lawrencei, excepting the petiole of the 

 areolet, which is only about ha.lf the length of the shortest side of the areolet; 

 basal area almost an acute angled triangle, nearly twice as long as wide at base, 

 areola pentangular, nearly twice as long as wide, the lower half almost quadrate, 

 finely granular and shining, the sides angled a little below the middle, petiolarea 

 a little more than twice as long as the greatest width, the sides angled in the 

 middle, the surface rather strongly transversely nigulose and shining, external 

 and external median areas finely granular and dullish, separated by a rather dis- 

 tinct raised line angled near the middle, internal and angular areas rugose, the 

 angular area lunate and small, inconspicuous; anterior and middle coxae black at 

 base, greater part reddish, posterior coxae black, with a narrow margin of reddish 

 at apex, anterior and middle legs with yellow trochanters, proximal tiochanter 

 of posterior legs brownish and black, the distal trochanter yellowish, otherwise

Type. — University of Kansas. 



Type locality. — Lawrence, Kansas. 



One specimen taken at night in May, by E. S. Tucker. 



Amorphota aiigusta n. sp. 



Very like Limnerium montanus Cress., from which it can be 

 distinguished by the sessile areolet an-d the larger basal area. 



J. — 7 mm. — Head. — Nearly as in L. lawrencei, the cheeks, however, not more 

 than half the width of the eye and the antennae thirty-three jointed. 



'ihorax. — With characters like those italicised in the description of Z,. lawrencei, 

 with the following exceptions: stigma light brown, the areolet quadrangular, 

 nearly quadrate; basal area smooth and shining, nearly quadrate, about as large
