"Tliey at once lieuan trying to fly and spent their strength against 

 the wire netting of the cage, the sexes ])aying no attention to each other, 

 from which I surmise that they seek mates from some other hrood. When 

 daylight comes tliey try to iiide, putting their head into any dark corner, 

 where tiiey remain all day without motion. 



"The males and females are easy to distinguish hy the charaeters 

 given in Horn's de"seri]ition, hut I note a further sexual eharaeter in the 

 granulation of the el\tra: in the males the lateral margin and the tip 

 liehind the tubercles is smooth, while in the females this area is distinetly 

 granulated. Also a .slight differenee in tiie shape of the thorax, that of 

 the males heing broader. The males also have a more shining lilack ap- 

 pearance than the females. 



"I have now thirty-six specimens of Dinapate wrightii, fourteen males 

 and twenty-two females. I can still hear the second brood at work and 

 liope to ha\e more emerge next year." 



In 1918 Mr. Richard T. Garnett added to our knowledge of 

 tliis remarkable beetle, in an article published in the Entomological 

 News. (1918. p. 41). 



He writes: 



"This extremely rare ]5ostrichid, called by Hubbard the "dodo" of 

 Coleoptera, was taken by the writer in Palm canyon on May 21 and 22, 

 1917. Every dead or unheaUhy specimen of the palm, AVashingtonia filifera, 

 in Palm, Murray, and Andreas canyons, was tiioroughly examined. Of 

 these only one log in the extreme lower end of Palm canyon contained the 

 beetle. This log, covered by driftwood, was wedged into a crevice in the 

 rock strata fifteen feet above the summer stream level. From this log on 

 the days mentioned 133 adults, 28 pupae and 17 larvae were taken. Of 

 the adults 81 were males and 52 females. When the log was discovered, 

 one adult had made its exit, as was shown by the freshly bored exit 

 hole. The colony therefore totaled 179. 



"Many other logs in these three canyons had exit holes in them, but 

 witli the exception of the one above noted all were black with years of 

 weathering. The average number of exit holes, making a count of 20 

 trunks, was 14, the highest number being 21 and the lowest 2. A great 

 many must perish and decay in their pupal cells if the colonies average 

 anywhere nearly as many as the one which I found. 



"A few of the adults were yet soft from their change from the pupae, 

 but the majority were hard and would undoiditedly have emerged in 1-14 

 days. Thus, if there are any survivors of this species, the time of emerg- 

 ence must be the latter part of June or the first part of July.
