I cannot apply Burrneister's description, or a more explicit 

 account of the characters of the insect received from Dr. Hagen, 

 to any species I have seen, with absolute certainty. Neverthe- 

 less I think the species probably identical with the next-noticed, 

 H. injurius. Burmeister states he had seen several males. How- 

 ever, I believe he did not know the male of either costatus or 

 subcostatus. His types possess no prothoracic valve ; neither does 

 any specimen of Haploglenius in Hagen's collection, as he in- 

 forms me ; hence I doubt not that all are females.

 clava nigra, extus supra infraque ochracea. Frons cervino fuscoque

 flavidi ; tibiis subtus fusco-lineatis ; tarsis piceo-nigris. (Abdomen 

 mutilatum.) Alae elongatae, sat latae, obtusae, vitreae; venis venu- 

 lisque nigris ; pterostigmate pallide flavo, nigro-venato : margine in- 

 teriore anticarum ante basin fere regulariter convexiusculo, angulo 

 axillari obtuso ( $ ). Exp. alar, antic. 40"', postic. 37"'.

 Neurop. p. 449.) Antennae alarum dimidio longiores. Thorax fusco- 

 flavoque varius. Pedes flavi ; tibiis extus fusco-lineatis ; tarsis nigris.
