30 BULLETIN OF THE BROOKLYN ENT. SOC. 



I fed a larva of Staph, maculosus with a caterpillar about 4 times larger 

 than itself, the larva seized the caterpillar at the neck and was beaten around 

 in the cage terribly by the jerkings and convulsions of the latter, but kept 

 on. and sncked the contents of it. 



Staphilirxus maculcsus Grav. F. (x. Schaupp, Bull. B'klyn 

 Ent. Soc. I. 42. Color eastaneous, abdomen dirty white. L. 20-25 

 mm. Found in July , August under stones ; makes a nest and 

 forms a brown shining cliitinous pupa 14 mm. long, develops after 

 15 to 18 days. 



Leistotrophus cingulatus, Grav. F. G. Schaupp, in lit. 

 Very similar to the above, but much smaller, only 12-15 mm. long. 

 Pupa also very similar ; developed after 11 days. 



SILPHIDAE. 



The larvae of Silphidae resemble those of Staphilinidae, but differ 

 by having six ocelli ; they are also somewhat broader. 



Head horny, convex above, flat beneath, usually bent down- 

 wards ; antenna? at the sides of the head, four-jointed, the first 

 short and thick ; mandibles short and strong, dentate. Maxilla' 

 well developed', palpi three-jointed. Abdominal segments nine, 

 cliitinous above and fleshy beneath. Nine stigmata. Feet with 

 one claw. They usually live under the surface of the earth on de- 

 caying animal matter, the fullgrown larva goes deeper and forms 

 a.n oval cocoon, of which the imago developes after three to four 

 weeks.

I should think the raising of Silphidae would be a very easy thing ; and I 

 shall try it next year. Take a box filled one foot deep with earth and cover- 

 ed by fine wirescreen. Place in it a dead mouse or bird and several speci- 

 mens $ and 2 of a Necrophorus or Silpha. Let the box remain in the yard or 

 the garden ; after a week or so remove the imagines, larvae and pupae will 

 be obtained. 



SCAPHIDIIDAE. 



I cannot give a description of the larvae of this family, although 

 I have raised those of Scaphidium piceum, (and its spotted var- 

 iety). They were found in rotten linden logs and developed in 

 July and August.
