Notes on the Siricidae of California (Hym.). 



1. Sirex apicalis male of areolatus. 



In October of 1907 I collected at Messa Grande, Sonoma County, 

 California, five Siricids (two males and three females) that were fly- 

 ing about together. The females had also been seen depositing their 

 eggs in some freshly cut redwood logs. 



Dr. E. C. Van Dyke tells me this latter observation is of some eco- 

 nomic importance, the species of the Siricid that bores into redwoods 

 having been previously unknown. This insect is the most common of 

 the few that bore into the heartwood of the tree. 



Though not found in the act of copulation, the flight of these insects 

 together makes me believe they are male and female of a single species. 

 Both sexes are common about the San Francisco bay region, specimens 

 in the California Academy of Science and in my own collection having 

 been taken from San Mateo, San Francisco and Alameda Counties. 



Using Dr. J. C. Bradley's paper, "The Siricidae of North America" 

 (Reprint Jr. Ent. & Zool. Pomona College, Claremont, California, 

 April, 1913), the females fit the description given for Sirex areolatus, 

 race areolatus (Cresson) Kirby. The male, however, runs down to 

 Sirex apicalis Kirby. 



Konow has already considered apicalis to be a synonym of areolatus 

 and has described a male and female from Vancouver as Paururus 

 areolatus. On the other hand, Bradley believes his new species Sirex 

 obcsus to be the female of apicalis. This is apparently very improba- 

 ble, as I have compared a female of this species and find it very dif- 

 ferent from the female of "apicalis." 



We can therefore assume for the present that Sirex apicalis is the 

 male of areolatus and that the name for this species should be Sirex 

 areolatus (Cresson) Kirby.
