114 GEO. H. HORN, M. D. 



The first joint of the hind tarsus is one-third the length of the 

 tibia, and about as long as the following joints together. 



From the localities given by Dr. LeConte I am quite confident 

 that this species was mixed by him with torquatus, from which it 

 differs in having all the tibiae and tarsi yellow, and by the smooth 

 thorax and much less punctate elytra. 



Occurs in California, Santa Barbara, San Mateo and Dunsmuir 

 (Wickham). 



It. laticeps n. sp. — ^Moderately elongate, parallel, beneath black, head and 

 elytra bluish green, thorax yellow, Auteiniie two-thirds the length of body, 

 piceons, the basal three and part of fourth yellow, joints 2-3-4 gradually longer. 

 Head smooth, the transverse impression angulate, deep, entire. Thorax about 

 a half wider than long, widest in front of middle, sides anteriorly arcuate aud 

 thence slightly oblique to base, hind angles slightly prominent, disc convex, 

 smooth. Elytra twice as long as wide, the sides nearly parallel, surface aluta- 

 ceous, very sparsely, finely punctulate; prosternum very narrowly prolonged 

 between the coxfe. Legs piceous, the anterior tibia and apex of femur and the 

 apex of middle femur and base of tibia yellow. Length .15 inch. ; 3.75 mm. 



Male. — First joint of middle and anterior tarsi slightly thickened ; the last 

 ventral segment broadly truncate and slightly concave. 



Female. — Last ventral oval at tip. 



The first joint of the hind tarsus is one-third the length of tibia 

 and scarcely as long as the following joints together. 



When viewed from above the front is rather flat, and the eyes a 

 little more prominent than usual, giving the head a somewhat broader 

 appearance. 



This species is closely related to torquatus, but has a differently 

 shaped and smooth thorax. The elytra are also alutaceous and 

 much less punctate, and the legs differently colored. 



Two specimens ; California, region unknown. 



li. Wickliaiui u. sp. — Oblong, nearly parallel, beneath piceous; above, 

 head and elytra bluish green, thorax yellow. Autennse longer than half the 

 body, piceous; joints 2-3-4 gradually longer. Head smooth, the frontal trans- 

 verse impression scarcely reaching the eyes. Thorax about one-fourth wider 

 than long, widest in front of middle, base and apex equal, sides arcuate, hind 

 angles not prominent, surface smooth. Elytra not twice as long as wide, very 

 obsoletely sparsely punctate, the surface shining; prosternum narrowly pro- 

 longed between the coxse. Legs piceous with greenish lustre, all the knees 

 faintly paler. Length .14 — .16 inch. ; 3.5- -4 mm. 



Male. — Last ventral segment with a narrow, slightly prolonged truncation 

 limited each side by a notch, the disc slightly concave ; tarsi not dilated. 



Female. — Last ventral oval at tip. 



The first joint of the hind tarsus not quite a third the length of 

 the tibia and not longer than the next two joints together.
