XXXIX.—Characters of some apparently undescribed Ceylon Insects

An Apparently Undescribed Infectious Exanthem *

During the past few years, patients with an unidentified acute febrile illness have appeared on the wards of the New Haven Hospital. They present similar signs and symptoms. We have been unable to recognize this syndrome as that of any of the known infectious diseases. We believe that it may be a new disease and we are taking this opportunity to report eleven cases seen in the past five years, ...

Determination of essential amino-acids in some Ceylon vegetables.

Until recently methods of amino-acid analysis had been applicable only to purified proteins. In a few instances the effects of impurities have been partly ascertained, noteworthy being the work of Chibnall and his colleagues (Chibnall, 1939) and of Lugg (1938a) on the crude proteins of grasses. The development of the microbiological method in recent years has led to an extension of analysis to ...

Sequence-based species delimitation for the DNA taxonomy of undescribed insects.

Cataloging the very large number of undescribed species of insects could be greatly accelerated by automated DNA based approaches, but procedures for large-scale species discovery from sequence data are currently lacking. Here, we use mitochondrial DNA variation to delimit species in a poorly known beetle radiation in the genus Rivacindela from arid Australia. Among 468 individuals sampled from...
