NORTH AMERICAN COLEOPTERA. 279 



Bryaxis Be/fragel Lee. has the second dorsal segment of the male 

 excavated or depressed ; the depression, deepest at the base, takes in 

 half the width of the segment, arcuate, indefinitely limited and 

 shallow, and in the middle of the depression there is a carina rising 

 from a small bilobed basal elevation. 



Bryaxis cylindrartus n. sp. % . — Piceous black, impunctate, thinly pu- 

 bescent, elyti-a dark red ; antennje, palpi and legs brown. Length 1.4 mm. 

 Head with three equidistant, equal, large, spongipubescent fovege, not more dis- 

 tant mutually than their diameter; prothorax wider than the head, convex, 

 lateral fovese not larger than those on the vertex, circular not fully seen from 

 above, median fovea very small ; the base twice as broad as the neck ; elytra 

 rather convex, thinly and minutely punctulate, shoulder width not exceeding 

 the width of the prothorax, tip twice as wide as the base of the prothorax ; dis- 

 cal lines very long, convergent ; first abdominal dorsal segment two-fifths as long 

 as its width, with long divergent, at the base closely approximate cariufe ; an- 

 tennae. (PI. IV, fig. 18) nearly as long as the head, prothorax and elytra together, 

 all the joints cylindrical, none less than twice longer than wide, the fifth three 

 times longer, the last as wide as the first, three times longer, and as long as the 

 three penultimate together; the middle tibise spurred before the tip, and the coxae 

 armed with a curved thorn. 



North Illinois. The 9 I have associated with this species. 



Bryaxis facilis Casey, according to the author's testimony by kindly 

 naming a specimen for me, is nearly related to B. divergens, from 

 which it differs by being narrower across the shoulders and the elytra 

 impunctate. 



Bryaxis depressifrous n. sp. — Piceous black, impunctate, pubescence 

 short, sparse, elytra red, with a dark brown basal fascia at the humeral calluses; 

 legs, antennae afid palpi red. Length 1.3 mm. Head (PI. IV, fig. 17) from the 

 mouth to the base longer than wide, prognathous, from the base to the frontal 

 declivity one-half as long as the head is wide, eyes included ; the front trilobed 

 or deeply bisinuate; the lobes elevated, leaving two furrows, each of them con- 

 necting the large occipital foveae, which are nearer to the declivity than to the 

 base, the larger medial elevation connects the occiput with the frontal declivity, 

 the lateral elevation punctured, the declivity perpendicular, bearing at its 

 bottom a transverse oval pubescent spot like B. compar ; clypeus and labruni 

 simple and nearly horizontal; antennae with the first and second joint as thick 

 as the last joint, eighth, ninth and tenth trapezoidal, very transverse, the inter- 

 mediate globular or obconical in the third and fourth, about half as wide as 

 the second ; elytral discal lines convergent, the abdominal basal cariuae short, 

 including one-third of the segmental width. 



California, Alameda County (Chas. Fuchs). Three females, which 

 ought not to be described, but their peculiarities which might lead 

 to the discovery of the males. 



Bryaxis compar Lee. is identical with B. franciseana Casey (teste 

 Casey).
