This form was found common under leaves, etc.. during!: the 

 winter months of i9o_:;-o4 at Ithaca, N. Y.

Several specimens from Austin, Texas, (March, 1903, Prof. 

 J. H. Comstock) and from Claremont and Catalina Island, Cali- 

 fornia (C. F. Baker), agreeing fully with Meinert's redescription 

 of Wood's type. Dissection of the mouthparts shows this species 

 like the two following, to belong to Haplophilus of Verhoeff.

 widety rounded, not emarginate between the bases of the antennae. 

 The sides caudad of the anterior rounded portion flrst nearly straight 

 or slightly incurved and diverging, then weakly convex and a little 

 converging to the posterior margin which is wide and a little excurved. 

 Frontal plate not discrete. Basal, plate about six times wider than 

 long.. 



Labrum free, medianly deeply emarginate, the free margin with 

 numerous teeth. Mandibles with four pectinate and a single dentate 

 lamellae, the latter with as many as seven moderately long and api- 

 cally obtuse teeth; in general structure conforming to type of genus.
