surface rugulose. Exposed portion of wings very small, not one-seventh 

 of the length of the tegmina, rounded, surface as in the tegmina. Abdo- 

 men centrally expanded, the surface beset with fine hairs, and toward the 

 apex with distinct bristles. Supra-anal plate narrow, transverse, the api- 

 cal margin truncate, centrally with a broad, longitudinal depression. 

 Forceps very short and stout, simple, the tips meeting, the whole with a 

 strong upward curve. Subgenital plate narrow, transverse, apical mar- 

 gin very broadly rounded. Limbs stout, the femora considerably inflated. 

 General colors solid black and reddish brown. Head polished black, 

 antennae, palpi, mandibles, and a trace on the clypeus brown. Pronotum 

 brown, palest laterally. Tegmina and exposed portion of wings dull 

 black. Abdomen dark brown, each dorsal segment edged with yellowish 

 brown ; ventral surface uniform dull ochraceous. Forceps and limbs rich 

 reddish.

Another Yucca-feeding Insect. 



By Mary. E. Murtfeldt, Kirkwood, Mo. 

 The Yucca plant, which has contributed so largely during 

 the past twenty-five years to the fascinating chapter of the in- 

 terrelations of plants and insects, still continues to afford inter- 

 esting subjects of study to the entomologist. As an example 

 of this, while collecting moths of Proriuba and Prodoxus from 

 the blossoms of Yucca filamefitosa on June 15, 1902, I perceived 

 that the segments of the perianth were extensively mined by 

 small larvae of exactly the color of the blossoms, but which 

 betrayed their presence by the large transparent spots which 

 resulted from their appropriation of the opaque tissue. As a 

 micro-lepidopterist I was naturally disappointed to find, upon 

 examination, that these were coleopterotis larvae, but deter- 

 mined to make the attempt to rear them, and as it was very 

 probable that the parent insect might also be found in the 

 flower, a number of small beetles were taken, among which 

 was a handsome little Nitidulid of a red-brown color with 

 black elytra which were truncate and abbreviated. My con- 

 jecture that these were the parents of the miners proved later 

 to be correct.
