422 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



and it should be stated that Bowditch based his opinion on a 

 Suffrian type {&) sent him for study. Through the courtesy of 

 Mr. Bowditch I was permitted to examine this type, but it did not 

 seem to me to be identical with the present species, which con- 

 clusion is confirmed by a recent study of a female type of spu- 

 marius sent me by Dr. Taschenberg. Further remarks on this 

 matter will l^e found under spumarius. 



102. Pachybrachys spumarius Suffrian 



From a female specimen — supposedly a type or cotype — from 

 the Suffrian collection, I have drawn up the following description. 



Form very robust, similar in general facies to roboris but stouter than any 

 example in a rather long series of the latter species now before me; general 

 color dull yellow with dark brown punctures and rather diffuse markings. 



Head thickly punctate, front flat, markings heavy; eyes separated by twice 

 the length of the basal antennal joint. Antennae fuscous, paler toward the 

 base, half the length of the body, the tenth joint very slightly more than twice 

 as long as wide. 



Prothorax short, strongly transverse, sides somewhat strongly rounded 

 posteriorly, widest at about basal third, punctuation rather fine and dense, 

 with small scattered smoother spaces, the side margins distinctly smoother, 

 standard markings broad, brownish fuscous in color. 



Elijira densely confusedly punctate as far back as the shield and nearly to 

 the sides, the declivity deeply striate, the seventh stria scarcely impressed 

 basally and not very well marked, the eighth stria distinctly impressed through- 

 out and with a strong basal sigmoid sinuation; marginal interspace punctate, 

 the punetures becoming more widely spaced and in a single series posteriorly; 

 shield distinct, small, subtriangular, yellow; standard spots not well defined, 

 the outer basal spot on the shoulder knob distinct, the middle outer spot nearly 

 wanting, posterior spots confluent into a rather narrow, not very conspicuous, 

 transverse fascia at the beginning of the declivity; inner basal spots suffused 

 into a broad indefinite discal cloud. 



Pygidium in great part yellow. Body beneath brownish, abdominal apex 

 yellow. Legs yellow with brownish clouds on the femora and tibiae. Front 

 claws slightly larger than those of the four posterior feet. 



Length 3.25 mm.; width 1.95 mm. 



This specimen bears the number "30490" l)ut no locality 

 label. Suffrian however gives the locality "Carolina" for certain 

 of his specimens, while others from (or in) the Chevrolat Collec- 

 tion are without other locality than North America. 



I am unable among the thousands of specimens at hand to 

 match this Suffrian female, nor can I find a male that is a reason- 

 ably sure mate for it. I am however placing provisionally as 

 spumarius a male from Tumbling Gap, Ala., .sent me by Air.
