SUBFAMILY V. DECTICIN.33. 593 



had seen were taken at Arner, Aug. 9. "They were found in the 

 more open parts of a dry upland wood consisting chiefly of oak. 

 Most of them were found on the short grass which was growing 

 on the slopes of a ravine in the wood." 



276. ATLANTICUS PACHYMERUS (Burmeister), 1838, 712. 



The important features of difference between this species, as identified 

 by R. & H., and A. testaceus are given by those authors (191Ga, 54) as fol- 

 lows: "Caudal femora in both sexes of pacJiymeriis at least twice, male, or 

 more than twice, female, as long as pronotal disk; cephalic and median 

 limbs relatively longer; greatest caudal width of pronotal disk equal to 

 54 to 66 per cent of greatest length of same; prosternal spines more acicu- 

 late and elongate and mesosternal lobes more acute. Male with pronotum 

 less expanded caudad, the divergence of lateral carinas less pronounced; 

 tegmina well produced, the portion distad of the stridulating field distinctly 

 shorter than in testaceus (Fig. 194, b); cerci more slender and more acu- 

 minate, the apex more produced, the tooth more nearly median than in 

 testaceus; subgenital plate with distal margin rectangulate-emarginate to 

 acutely subfissate; styles slender and relatively elongate. Female with 

 lateral carman of abdomen distinctly and median carina slightly more pro- 

 nounced; ovipositor of approximately the same length as in testaceus but 

 relatively much shorter, being considerably less than length of caudal fe- 

 mora. Subgenital plate more deeply divided, the lateral portions rotun- 

 dato-rectangulate" (Fig. 194, b.) Length of body, $, 23.2 26.7, $, 20

Southern Pines, N. Car., July 2 (Davis}. Rurmeister's types 

 of jHtrlu/nicnis were from Germar's collection and labelled "South 

 Carolina," without name of collector or region of the State. His 

 brief description was as follows : 



"Fusco-griseus, pronoti lateribus infuscatis, macula ad sinum marginis 

 postica flava; vertice abdomineque toto unicoloribus. Male, elytris liberis 

 fornicatis. Female, elytris nullis; vagina recta, abdomine longior. Long, 

 corp. 9" (18.7 mm) ; femor. post. 8" (16.6 mm)." 



Of this description and their placement of the species K. & H. 

 doc. cit.) say: "We are able to place Burmeister's name on 

 this species by a process of elimination, * * * the three words 

 describing the male, 'elytris liberis fornicatis.' clearly referring 

 to this species, testaceus or davisi ; of these only the present form 

 occurs near the coastal region of South Carolina from which the 

 original material of paclii/iin'nift probably came. The characters 

 given for the female are only sufficient to separate that sex from 

 nioiiticold. The length of the body and of caudal femora as given 

 by I>urmeister, while less than any found in the material before 

 us, do not at all invalidate the claim of this species to his name.
