suture, by the longer as well as the shorter hair of the thorax being 

 inky black instead of the shorter gray, and by the general surface 

 of the body being covered with a denser covering of hair, both 

 short and long. Eximius also has a different life, being found 

 exclusively upon the soft wood trees, such as the California laurel 

 {Umhellularia calif ornica Nutt.), the willow, the alder and the 

 wax myrtle, and living, so far as I have observed, exclusively upon 

 the Ptinidse. 



Hydnocera quadrimaculata n. sp. Black, moderately shining; 

 antennas except outer part of club, inner surface of anterior tibia 

 and first tarsal joint and femur at junction with trochanter, and 

 four elytral maculations, yellow ; body very hairy. Head as broad 

 as elytra at base, densely, finely rugose, front not impressed, 

 clothed with sparse, moderately long, brownish black, erect hair. 

 Thorax slightly narrower than the head, broader than long, rather 

 finely, rugosely punctate, sides moderately and regularly dilated 

 anterior to middle, pubescence like that O'f head only longer, 

 intermixed with sparse shorter coat of ashy pubescence. Elytra 

 but little shorter than the abdomen, about two and one quarter 

 times as long as broad, sides nearly parallel, apices oblique on outer 

 part and separately rounded near suture; humeri distinct; disc 

 feebly convex; suture strongly depressed at base; surface with a 

 greenish lustre, the anterior yellow maculations just back of base 

 and less distinct, the posterior just back of middle, more or less 

 circular and distinct, rather coarsely and posteriorly confluently 

 punctured, an oblique depression running from humeri inwards 

 and a more circular one just posterior to posterior maculation, 

 pile on anterior half similar to that of thorax and on posterior half 

 much shorter. Underside and legs more shining, with more of a 

 greenish luster, more finely and sparsely punctured, and clothed 

 with longer, erect and shorter semi-erect ashen pile. 



Length, 5.5 mm., breadth, 1.5 mm. 



Type in my own collection, a unique collected near San Diego, 

 Cal, July 4, 1914, by Mr. E. P. Van Duzee and kindly presented 

 to me. 



This species can be easily separated from any of our other 

 western species by its size and markings.
