longer than second and third together. Venter finely and closely 

 punctate, with a coating of fine incumbent hairs.

Because of the character of the lateral margins of the pronotum 

 this genus should be referred to the tribe Myodochini, closely related 

 to Ptochiomera Say. It has no affiliation whatever with the other 

 species listed by American authors in the genus Rliyparochromus; in 

 fact this genus does not appear to occur within the United States. 



Valonetus new genus. 



Body, antenn?e and legs strongly pilose, not shining. Head lightly 

 exserted, a little wider than long, the width across eyes subequal to 

 anterior submargin of pronotum. Basal segment of antenna shorter 

 than basal segment of rostrum, well extended beyond apex of tylus. 

 Bucculse lightly elevated, running to base of head, first segment of 

 rostrum reaching base of head. Pronotum without any evidence of 

 a collar anteriorly, obtusely constricted just behind the middle; lateral 

 margins obtuse, terete ; anterior lobe finely and obscurely punctate, 

 posterior lobe wider and more coarsely and sparsely punctate. Scu- 

 tellum equilateral. Clavus deflected to corium, with three regular 

 rows of punctures. Costal margin of corium convexly arcuated. An- 

 terior incrassate femur provided with three or four sul)ap:cal teeth 

 and pilose throughout. Posterior tibia with short pilosity. Posterior 

 tarsus with basal segment longer than second and third together. 



Because of the character of the pronotal margins, position of the 

 ventral opaque spots of the fourth abdominal segment and the ab- 

 sence of a collar this genus must be placed close to Ptochiomera in 

 the tribe Myodochini. 



Valonetus pilosus new species. 



Color ranging from ferrugineous to pale castaneous ; posterior margin of 

 pronotum, costal margin of corium, acetabulse, legs, antennae and rostrum 

 ochraceous. Head triangular; eyes strongly protruding; preocular sides of 

 head to base of antennae very short, scarcely longer than the postocular space. 

 Antenna with first segment extended beyond apex of tylus by nearly one-half 

 its length, this segment subequal to third, which in turn is slightly shorter
